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.

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.
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.
