The SlumberJack Lapland 20 F is a 3-season mummy style sleeping bag, and by 3-season, I mean a sleeping bag good for all but the coldest winter temperatures I usually encounter and perhaps a little warm for mid-summer conditions.  However, good venting can help alleviate sweltering in the hottest weather and additional clothing can be added to carry the bag down to rather frigid temps.  Also, keep in mind that some folks sleep warmer than others in identical conditions.  In my opinion a 20 to 30 degree bag is probably the most versatile temperature rating for someone who just wants one or can’t afford several sleeping bags.  Having said that, the Slumberjack Lapland comes in a verity of temperature ratings, a 40 F, 20 F, 0 F and a -20 F.  If you prefer all down the Sojurn series is the identical bag but uses the same DriDown the Lapland series uses for the top throughout the bag.

The Lapland series is a hybrid bag that utilizes DryDown on the top side of the bag and synthetic insulation on the bottom side of the bag.  I copied what Slumberjack has to say (see Slumberjack website information below) about why this insulation combination is good but it also means the bag is not going to be as light or compressible as a full on down bag.  At 3 lb 5 oz I still feel this is a good option for anyone looking for an economical bag that is well made.  Slumberjack also says the Lapland series is a “relaxed” mummy.  All this really means is that the bag will fit larger folks.  I’ve owned a few 20 F mummy bags and I can attest that this one is indeed pretty relaxed.  In fact, I will often get the longer version of a bag because they generally make them a few inches larger in circumference.  In fact the long Lapland series is 2 inches bigger around at the shoulder, hip and foot areas.
The construction (sewing, zippers etc) of the Lapland 20F looks solid.  The outer material appears to be nylon but the tag says 100% polyester.  It is not a stretchy polyester, that’s for sure.  Is is a drab green color with orange zippers.  It has an orange Lumberjack Logo up at the left shoulder and  “20° Lapland” is printed below the side zippers near the foot end (on both sides).  The liner is black and also 100% polyester.  There are draft tubes along the entire length of each side zipper as well as one across the neck area of the bag.  There are two cinch cords to help seal off the bag around the face.  One is around the hood while the other is across the neck area.  The care instruction are printed on the tags but basically, it says hand wash or use a front load machine. Use cold water and a mild detergent. I have a top load washer but it is the new style without the center agitator so I will use it if I need to wash the bag.  It recommends drying in a commercial dryer on low heat or line dry but do not wring out or twist the bag. One other note, the tags state 3 lb 3 oz while the website says 3 lb 5 oz.  I weighed the Lapland 20 F inside the provided stuff sack at my local post office.  According to their scales it weights 3 lb 6 oz.  
According to Slumberjack, one of the major advantages of this bag is that it can be used with the arms out.  I know I feel claustrophobic in a regular mummy bag so I can see where this would be a nice feature.  However, they fail to mention that the same arms out feature also means I can put the bag on with my feet out.  You might be wondering why this would be something to look for in a sleeping bag.  For tent dwellers it probably isn’t a big deal, but for a hammock user like myself, getting in a mummy bag is a challenge.  So far I have tried several bag systems and the only easy entry was using a bag made like a snowmobile suit or a bag that let me get my feet out.  I have also just worn enough cloths to stay warm.  Think hunting cloths made for sitting in a cold tree stand all day.  In my experience a good mummy sleeping bag is more efficient and less bulky so I had to decide if the ease of getting in my hammock was worth the extra weight and bulk my hunting cloths added.
Since I’m talking about bulk, the stuffed size closely matched what the specifications listed but it is not stuffed as compactly as possible in the supplied stuff sack.  A good compression stuff sack would help shrink it down a little more.  The bag also comes with a mesh storage bag so that the bag can be properly stored between uses.  There are also two small loops of fabric at the foot end so the bag can be hung if desired.   Here is a size comparison of the stuff sack and the storage bag.

Trying it out
I don’t like to say much about a sleeping bag until I get a chance to spend at least one night in it.  It was very warm overnight the first several days after getting the bag but fortunately, the temperatures dropped drastically about a week later and I was able to try the bag on a short overnight hike to see how it worked with my hammock.
My first test was to see if I could stand up beside my hammock in the bag but with my feet outside the bag.  The next test was to see if when I laid down the bag stayed in place and if it was easy to get my feet back in and the bag zipped properly for the night.  My last test was to see how roomy the bag felt with my arms inside the zipped up bag as they would be when I was pushing the lower limits of the bag.  It passed the first two test with flying colors but I will admit, I felt a little closed in when I completely zipped the bag.  However, since only 57 F when I first got in the bag and only dropped to 51 F by the next morning I was able to unzip the upper portion of the bag and was in fact a little warm for most of the night.  I liked that I could wear my crocs as I prepared to lay down and slip them off after sitting down in my hammock.  This will be more important as temperatures drop later this fall and on onto winter.   Getting my feet inside the bag after stretching out in my hammock wasn’t the most graceful affair but it sure beat the struggle I’ve experienced trying to get in a normal mummy bag.  I got lots of practice getting in and out of the bag because I ended up needing to get up to pee 4 times.  The first three times I got up by just unzipping the right side of the bag and hoping out of the hammock.   Then I would enter the hammock by repeating the earlier process. The last time I woke up at around 2 AM and decided to see if I could just keep the bag on and still go pee.  Getting my feet outside the bag was about like putting them in.  Not easy but not that hard.  I was able to walk several feet to my spot and take care of business just fine.  I woke up at 5 AM for the last time.  I was warm but I had zipped the bag closed on the lower end and almost closed at the head end.  Overall I was very pleased with the performance of the bag.  Now I am looking forward to some cooler temperatures so I can test the bags true warmth.  In the meantime, here are a few photos of how I used the bag.

Keep the furnace evenly warm with our zone insulation system. We used DriDown insulation on top – where you want it, while our anti-compression Slumberloft-PRO ground layer maintains warmth below you. DriDown uses a proprietary treatment to create a hydrophobic finish on each down plume, allowing the insulation to stay dry longer, loft better & dry faster than untreated down. Slumberjack’s unique “arms-out” feature allows you to keep insulation on your chest and head while freeing up both arms to manage tasks without leaving your bag. Dual zippers provide unrivaled ventilation options and a relaxed mummy silhouette provides an excellent combination of comfort and thermal efficiency. We’ve also added waterproofing at the head and foot box, keeping the areas that touch the tent dry.

Update: November 30,2016
I have used the Slumberjack Lapland 20 F on four overnight trips so far.  I don’t have a lot of new information to add to what I already reported after the first overnight hike but I was able to use the bag in cooler weather.  So I’ll just cut to the chase and focus on that night.
The temperature as I hiked to my campsite started at 62 F but it was already down to 55 F by the time I hiked the 5 miles to my destination.  I was dressed in long pants but carried some heavyweight wool bottoms just in case I needed them.  Turns out I did not.  For my upper body I had on a long sleeve cotton flannel shirt over a regular cotton tee.  I packed the matching heavyweight wool top and also carried a light jacket which I wore after arriving at my campsite.  I ended up sleeping in the pants I wore hiking in but did change into the long sleeve wool top. I used the jacket as a pillow and had on thick wool socks.
I started the night feeling rather warm in the sleeping bag and had to vent it quite a bit.  However, temps dropped rapidly and by 11 PM it had dropped to 48 F and I pretty much zipped up everything. I woke up at around 3 AM feeling chilly but the reason was because I felt cold on my back side.  I was using the bubble pad that goes in between the layers of my double bottom hammock.  This pad is wide enough so that I was able to easily stay on the pad but it is just not very thick. By 5 AM it had dropped to 38 F and I was definitely cold on my back side.  I got up just as soon as there was a hint of daylight, put my jacket on and started striking my camp.  I have a few other pads and packing an extra is aggravating but not as aggravating as getting cold.
My opinion of this bag being ideal for hammock camping is the same.  It works much better than a regular mummy bag and I can get out of my hammock for nature breaks without getting out of the sleeping bag.  Well, as long as no squatting is involved.  This was especially nice on the coldest night to date.  It is also great when I needed to zip my bag up completely.  I find this extremely difficult to do in a regular bag.  On nights when I could have just used my bag as a top quilt it does not matter.  In other words, it goes back to being able to put the bag on over my shoulders with my feet out and lying down while keeping the bag in place rather than trying to wiggle into a regular mummy bag in a position that allows me to zip the bag up once I’m in my hammock.
I did notice that on this night that I got a few leg and rib cramps while trying to get my feet inside the bag.  I’m not sure if it was due to hiking five miles or the cooler temperatures.  I have no trouble reaching down to adjust the zippers once I’m inside the bag so adding a few more inches towards the foot end would be a big help for someone like me who is not all that flexible. And of course, a lot of folks using the bag would not be using it like I am, so again, it’s just something that would help it be more hammock friendly.
The last thing I’ll mention is the durability of this bag. I have not used it a lot but I have not babied it while using it. The materials seem to be very robust and the zippers have functioned flawlessly.  I did snag one of the side zippers on the draft tube a few times but a quick reversal and using a little more care rectified this each time it happened.
Stay tuned for my final update in about a month from now to see how the bag works now that winter has arrived.  I’ll definitely use more pads if I have a chance to camp in even colder weather.

Slumberjack Lapland 20

Home for the night

I was finally able to use the Slumberjack on a multi-day hiking trip. This was along the Pinhoti Trail in east central Alabama, January 19th – 21st. You might be thinking I got to use the bag in cold temperatures but alas, it was downright warm the entire trip, with lows of around 50 F and highs near 70 F. It was also stormy which caused us to change our hiking plans slightly so as to have a shelter nearby and also not so far to hike out to a trail head in case of an emergency.
I slept in my Hennessy Deep Jungle both nights and was using the bubble pad that goes with it. On the first night it came a strong thunderstorm around 8 PM. I got inside my hammock and rested while listing to the rain, wind and lightning. When it eased up I got up to pee and decided to walk over to the shelter where other hikers were spending the night. They were surprised when I reported I did not get wet. However, I left my hammock side entry zipper open and when I returned to my hammock about an hour later I found a big pool of water in it. The fly had sunk down inside the opening and was letting rain just spill over into my hammock and the bubble pad was holding the water. My sleeping bag was just lying there in the water soaking it up. I slid the sleeping bag out of the way and dumped as much water as I could out and then spread my sleeping bag out and just laid down on top of it. I went to sleep fairly easily despite lying on a damp bag. Around midnight I needed to pee again but this time I when I got back in the hammock I used the sleeping bag as a quilt. I could tell it was damp but I still remained warm, in fact I had to vent a little to stay comfortable. By morning the bag seemed almost dry and there was just a small wet spot on the hammock bottom. I packed up my gear and we hiked the 2 miles out to my truck. I did not use the stuff sack that came with the Slumberjack Lapland 20 so it took up quite a bit of room in my pack but by putting it in first my other gear did compress it down considerably.

When I set up my hammock on the second night it was still fairly early in the day so I left the damp bubble pad out to dry and also hung the sleeping bag over the end of my hammock so it could dry some more. We then went on a day hike and then cooked supper back at camp. So, by the time I turned in for the night everything was dry. It was windy this night and felt a little cooler, but again, nowhere near cold. I used the bag as a quilt and slept very well. I did have to get up to pee twice and at 5 AM I was awakened by thunder the distance. I hurriedly packed my gear and walked over to the shelter and watched the storm roll in. It eased up around 8 AM and we made a mad dash for the vehicles.

When I returned home I took the sleeping bag out of my pack and spread it across the rail on my deck to air it out. I inspected it for any signs of wear and tear but it appeared to be in great shape. I carefully felt of the top section to see if any of the DryDown had clumped but it felt fine. After letting it air out for most of the day I put it loosely in my pack, ready for my next trip.

Final Thoughts
The Slumberjack Lapland 20 is a really good sleeping bag. No, it is not the lightest or most compressible 20 F bag available, but it is also much cheaper than the higher end bags. It certainly offers a lot of bang for the buck. The ability to put it on and walk around was especially nice on the colder nights I used it and made getting in and out of my hammock much easier than a traditional bag. When I used it as a quilt it performed about like any other 20 F sleeping bag would have. And last but not least, the bag can stand to get wet and still be depended on to keep me pretty warm. In other words, I did not have to worry about getting my bag wet and did on one occasion. In conclusion it is a good winter hammock bag suited for most of the temperatures I am likely to be using it. I’d like to thank Slumberjack and 4alloutdoors for making this test possible.
