Slumberjack Latitude -20 Degree Synthetic Sleeping Bag

So far so good. Although I missed that this was a left hand zipper on the over sized model. Not a big issue, but my summer bag I use as a liner is right handed (awkward) and my liner I just got or bivy is also right handed. So it's a little tricky from that perspective, but very comfortable bag. I'm 6'2" and 230lbs and I find this bag to be just the right size, room to move but not too much. Good sized foot box, comfortable with my size 13 feet without feeling cramped. I'm not an ultralight backpacker, but I'll take this on winter camping trips and hikes I was not off put by the weight.I did add a Woodland Camo Gore-Tex® Bivy Sleeping Bag Cover to the mix for an outer shell and wind block, seems to be a great paring, fit the bag really well and I feel like it really reduces the bag heat loss. I've only tested it in 15 degrees F and not for a night, just for an hour to test it, but I got hot in the bag and had to unzip and get my shoulders out, that's with the bivy cover on though. Just long underwear on.I plan to find a good 0-10 degree day and do an overnight outside camp trip one of these days, I just need the cold to align with the weekend. Iowa winter this year has been very inconsistent. I'll update this once I get more thorough field testing. Nice bag especially for the money though. No regrets at all.Update, forecast was warming up and I didn't want to miss my opportunity. Slept outside last night, it was 16 Degrees F, 9 Degree wind chill. I used a tarp draped over a rope as my shelter, so open air basically just blocked the wind. I had a double mat below me to be well insulated from the ground and I have a Military Surplus Bivy cover that I had zipped up 60% over my bag. I woke up once a little cold around 3AM and reusable hand warmer and stuck it in my bag with me. I was toasty after that. Woke up at 6:30 and it was 24 degrees F and I was hot. I wore long underwear and hat and muff. I think I could add a layer of fleece clothes and take this system down to 0 degrees with no worries. Knowing I can zip up the bivy cover also helps block any wind from being in a bad shelter. If you had a nice tent or warm shelter maybe colder temps would be fine too. Oh, and the head basket/hood is a little too big, it took some effort to get my face lined up with the opening after cinching everything closed. I did squeeze a small pillow in there though which may have complicated things slightly. Blame user error.I would buy this bag again. Great comfort and room for a big guy.

I didn't believe it when I the read reviews that said the zipper was poor quality and got caught alot. I have had quite a few sleeping bags and never really had trouble with the zippers because I take the time to move them slowly and make sure the material around them doesn't get caught in them. I figured the people who complained here were just being in a hurry and careless. Then I tried the Latitude.. Zipper is very small and even tho Slumberjack went to the trouble to make the material next to the zipper a heavy solid material , not silky nylon or dacron that kinda fluffs and can get caught in it easily, the zipper is just too small so that it is very closely set next to the material and gets caught anyway. If the zipper was large with big teeth it would have- just by its size a longer distance between zipper material where it is sewn to the sleeping bag material and more of a chance to push the sleeping bag material out of the way as you zipped. Otherwise I want to compliment Slumberjack on a nice warm, well lofted, nicely sewn sleeping bag. I do wish the hood wasn't already formed to fit ones head,I prefer just a drawstring so that if you want to lay it out flat in warmer weather and use a pillow, you can do so. When its already preformed as it is I just kinda bunch it up and use the hood as a pillow which I really dont like.. Another thing I wish sleeping bag manufacturers would consider...Not everyone wants to sleep with a hood around their head and their face exposed to the bitter cold air. I prefer to scrunch way down into the sleeping bag with my head totally covered and the open ends folded down..so I can breath warmed air from the bag... which keeps me alot warmer. Need a long size bag to do it. Most of the animals that sleep outdoors like foxes and wolves, put their nose under their long fluffy tail which warms the air they breath so they don't have to breath the biting cold dry air.

My son used this during our Elk Hunting Trip last week. The temps were in the 20's at night and we got snow for a day and a half. He was able to snuggle down in this bag and stay warm all night both on the ground and on a cot. I only have 2 complaints about this bag. First, I can't use it. I'm 6'6" about 300 and I could barely get the thing zipped around my shoulders. It might be long enough for me, but at my size it is unusable. Second, the stuff sack has no compression straps on it to suck it down and make it smaller. This made it a little bulky to carry on a backpack. That could be fixed with a different compression sack, but it would be nice if the bag it came with had the straps.

I had to acquire a couple of bags rated to something colder than what I already had. I had a couple of Marmot 40 degree bags but they aren't very comfortable in cooler temps obviously. We had a trip to Valley Forge PA and we were all planning for it to be a lot cooler than it turned out to be. First night was down in the mid 20s, second night in the 40s. First night the only thing that got cold was my feet. I had taken my socks off and did not put a jacket or anything over anything...second night I kept my socks on, put a jacket over my feet and I had a bivy sack on ....I was sweating. I was also inside an Alps Mountaineering Lynx 1....overall bags were good, I would recommend to others.
