Wenzel Lodgepole 40° - 50° Sleeping Bag

I cannot tell you how happy I am to have this new sleeping bag! I’m now sleeping so much better while camping. I love having the extra room!! After sleeping in a mummy bag for a few years, I am So Excited to be back in comfort. I also love how soft the material is too.  Full review

Wenzel Lodgepole 40° - 50° Sleeping Bag

The Lodgepole's roomy, oversized fit will allow you to sprawl out while keeping you toasty between 40-50 degrees with its quick-warming brushed liner, cozy fleece collar, and fleece-lined footbox. I'm 5'3" and I am a stomach sleeper. I like to have a knee up and in this bag, I can actually put my knee up. This is the biggest plus about this sleeping bag. The fleece collar is great too. I used this in my camper with the ac on 66° so I was able to use it and not sweat to death. The zipper worked… Full review

Alpine Design 45-degree Micro Lite Mesa Rec Bag

Great addition to one's warm weather gear kit. $4 at Amvets seconds store. Tried to find Alpine Design on net, nothing! Used with no clothing to 45° F.; works well. With base layer, would go much lower.  Wondering what the fabric and materials used are? The insulation factor is pretty good, must be some kind of fabric magic at work. Wonder what Alpine Design has to say about that? Anyone know how to locate that company? Full review

Therm-a-Rest Space Cowboy 45F

The Space Cowboy is a nicely featured 45˚F/7˚C sleeping bag for those seeking a highly compressible, lightweight synthetic sleeping bag option. This bag is readily stuffed into pack crevices or its supplied stuff sack, taking up less room at lower weight than a number of similarly rated bags (albeit at higher price), while providing mummy bag coziness with a draft tube and draft collar for unseasonably cool nights. In the American South where I live, we’ve had the first few flashes of summer-like… Full review

Ozark Trail Sleeping Bag

This is the most sh*t sleeping bag I have ever used in my life. There is absolutely no way to fix the damn chain. Ozark Trail, make better sleeping bags! Full review

Marmot NanoWave 35

Well built. Great for summer nights but not for cold weather. I am a Florida hiker/backpacker. I am one of those people northerners laugh at because I wear winter jackets when the weather reaches 65°F and below. Knowing my blood is thinner and I have my own internal insulation (weighing in at 150 lbs), I was hoping this bag would keep me warm. Although this bag is rated to 35°F, I was cooly uncomfortable at 52°F and below. On all occasions where the weather dipped below 55°, I packed wool pajamas,… Full review

Deuter DreamLite 500

Sweet, durable, comfortable, holds up to its ratings very well. If you don't have one, prioritize getting your Dreamlite. I truly love mine. For the guy with the cord issue, I thought the exact thing. Even considered sliding barrel lock up to perfecto tying a knot and cutting the extra off. But on one trip someone took my backpack. Luckily all my gear and sacks were in the tent with me. Man, figuring out how to lug my gear back out the trail without my backpack was a lot of trial by error and I… Full review

Sierra Designs Forty Winks

Good well-rounded synthetic bag. Medium weight, medium packed size, medium warmth, and durable. This was my first sleeping bag I ever bought, purchased in 2001. I have been happy with the bag, and I think it is a good bag in all categories.  It is not a very lightweight bag, nor does it pack down very small, but it's a mid-priced synthetic bag and I think it is everything that it's supposed to be. Overall I've been pleased with it as a general purpose, well-built bag. Since then I almost always… Full review

CRAZO Premium Hooded Envelope Sleeping Bag

This is a well-built envelope sleeping bag with mummy hood which is good for most three-season camping. The extra long and large size (86.6" x 31.5" ) assures comfort for adults even up to 6'11", and it allows you to use a liner or wear extra clothes to be warmer if it might get colder than the rating. As a retailer of this sleeping bag, I'd tested it several times with my friends before I placed the order. I have to say that I really love this sleeping bag. Honestly, I don’t like the narrowness… Full review
