Trailhead +20ºF

I do quite a bit of camping in the brush. Often 2-3 times a month. I preferably sleep by a fire, directly outside in the elements, and under a tarp or under nothing at all. I use a cheap sleeping pad For comfort and bit of insulation from the ground. With nothing but moisture wicking long johns and wool socks, This bag kept me warm in 18 degrees with 4 inches of snow in the surrounding creek bottom. We woke up to 2+ more inches of snow on the ground. My feet never even a hint of cold weather exposure. They stayed comfortable all night. The micro fleece inside is very cozy and my favorite thing about the bag. I hate sleeping bag materials, So this was quiet a relief. The wind was steady and crept in through the mummy hole, I tightened it down as far as it would crimp up leaving about. 1-2 inch hole for breathing fresh air on occasion. I simply faced the hole away from the wind so I wouldn’t suffocate in the bag or suffer from wind blast through the hole. Excessive wind can just be blocked by a pillow. Aside from the mummy hole - no wind made its way inside. I’m 5’11” with a 31” waist, Medium shirt size - smaller build guy. This bag is as small as I would ever want to go. Almost no room inside once it’s zipped up and I have no more head room hardly at all. My camp buddy made fun of me cause I was sleeping like Dracula Stuffed in a tiny coffin. I like to sit up on my sleeping pad and hang out around the camp fire. This bag made it impossible to sit with my legs crossed, but it has a two way zipper - I just opened the zipper from the bottom of the bag and was able to sit Inside the feet portion with my legs crossed the way I wanted and had the rest of the bag to wrap around me. Before discovering this method - I was super disappointed with not being able to sit Up in my bag comfortably. Although it’s a bit tight - This bag is now my favorite winter bag. I’ve tested It in record lows for my region and it easily passed. It’s also pretty lightweight and compresses in a compression sack extremely well. Highly recommend budget sleeping sack!

Just got my Trailhead 20+ from Amazon for a great price--I was excited when came in (as they were out of stock). So far I like this bag and from other reviews, I expect it will hold up. As other reviewers commented, there aren't a ton of choices in the synthetic, light and reasonable cost category. I like synthetics because I have kids and that means they'll use (or better said misuse) them at some point and better to know you're not ruining an insanely costly piece of equipment, not to mention the wet factor. This bag strikes the perfect balance of everything thing from cost, weight to features. I received the bag this week and immediately wanted to test it. Thankfully we had some mid-20 temps recently, so it made for a perfect testing ground. When I went to bed, it was in the upper-30s and by dawn in the mid-20s. The details on prepping for the evening: I put on a dry base layer (long sleeve top, long john pants, fresh wool socks and a stocking cap). I also slept on an inflatable pad. I was thinking about trying a liner, but I wanted to test the bag for it's rating and that's what I did. More details on this test: - For size comparison, I am 6 foot tall and weigh about 195. I wear a 42-L jacket. I'm not a huge guy, but not small either. This bag comfortably fits me. - The inner bag material isn't slick or slippery. I was actually concerned about this, but it made it easy to move around because the bag stays with your body as you turn. - The footbox has plenty of room, so your feet can move around without feeling cramped or having too much area to move around. - I hung the bag from the loops when I got it out of the box and slept in it the next night, there were no cold spots to notice. Store with the loops if you can (read the directions for any bag for storage). - Really liking the mummy hood drawstring. My old bag has a shoulder and hood drawstring. This simplifies the process and doesn't feel like you're going to hang yourself in the middle of the night adjusting. - The temperature rating does seem to be fairly accurate. I was not cold at 26-degrees (which is what it got to during my test), but I would say that if I were going to go too much more, I'd add a liner. Seems accurate. - Comes with a stuff sack. - Read the care directions if you are considering it, e.g. don't put in a washing machine. Here's the deal, you want to go down and expensive, go that way. Want a synthetic that is of reasonable price and that comes as advertised, this is the bag. I'm interested to find out how it holds up over time, but from everything that I can see to date, this bag is going to be a great investment. Item is as advertised. Happy trekking. Will update as necessary as I use on the trail. --- Update 10/2016 I had a minor issue with the bag. I contacted Teton Sports and they resolved the issue immediately. Another great reason to buy this bag. I still like this bag a LOT.

Overall, I think this is a very, very good bag. It is certainly warm enough to the temps I have tested it in, which is into the 20's. It is certainly quality and worth the money/deal I purchased if for. My only issue with the bag is that, for me, it can be tricky to get zipped up without a struggle. The zipper seems to get stuck frequently on me. Or, it could be user error and I simply need more yoga. Also, and this is more a user preference than an issue with the bag, is that I find myself getting a little claustrophobic at times. I'm not a big guy at 5'10", 180 lbs, but I am a gym rat and have rather wide shoulders for my stature. I find the mummyish design can be a little restraining for me. Foot box is much appreciated and ample for me, however, and like the design and features of the foot box. Again, this is user preference as I tend to like to sprawl out and extend my arms a little more than what the bag will allow. With that said, I will certainly continue to use this bag. I'm a big Teton fan for the quality and value they offer and find the workmanship to be above average, beyond the zipper issue. And like many other reviewers have stated, the inner fabric is very comfortable and unique to Teton, in my experience. It packs down well enough to fit in my Gregory Stout 75 to give an indication of its size for the trail. I find this very acceptable for a cold weather, synthetic bag. If you're looking for a cold weather bag that isn't the total, confining mummy style, while being a great value, I highly recommend this bag.

This sleeping bag is rated 2 degrees celsius comfort, -7 limit, -15 extreme.

This is a fantastic sleeping bag for the money. It is not considered light weight for some long distant hikers but, I do motorcycle camping and its light enough and small enough for that. I do mainly spring summer fall camping and this bag keeps me warm. I did a fall camping trip in Canada's Coastal mountains at 7000 ft elevation and i was a little cool (- 4C), nothing that flannel pants and a shirt didn't solve. Its very well made and I found they made the bag a little larger than your traditional mummy bag. As a 6' 3" 250 lb man the bag was comfortable to sleep in. Teton also made a larger than normal foot box so there is some movement for your feet, which i appreciate. The colour is a nice red and grey. The material used inside the bag is very comfortable and warm. The fabric on the outside appears to be very durable. The zippers work great. As with any bag I recommend a self inflating sleeping matt for warmth and comfort from the rocks, sticks etc. I highly recommend this sleeping bag for people that don't want to spend a fortune and get value instead. It is exceptionally well made. As with any sleeping bag be sure to store it out of its storage bag and hang it up or lay it on a spare room bed to retain its loft until your next camping trip, the bag will last for years. I don't regret buying it. Value in this case does not mean compromise. I have had this sleeping bag for years and its still the one I use. I would not hesitate to buy again. Teton makes great products.

Very comfortable, it also is very compact. Will be used regularly!

NOT comfortable at 20F/-7C, but usable down to around freezing. Best at 40F/5C and above. You will NOT be comfortable at 20F/-7C with this sleeping bag, in fact you'd be far too cold to sleep. However, with thermal underwear, warm socks, a beanie (or head covering of some sort), a quality sleeping pad, and inside of a 4-season tent, I've used this sleeping bag in sub-zero temperatures without any real issues. That being said, anything below freezing is uncomfortable, even with the above mentioned gear. Just remember not to open it once you settle in for the night, or you'll lose a lot of heat... In terms of comfort (which highly depends on the individual), I'd say it's "acceptable" down to around 32F/0C (while wearing the aforementioned cold weather gear), and warm or "comfortable" down to around 40F/5C (with the mentioned gear). The 20F/-7C rating is likely the "survivable" temperature, at which you would be very uncomfortable and likely unable to sleep due to the cold, but not die from hypothermia. I've also used it in warmer temperatures by simply reducing what I wear while sleeping, and leaving the bag unzipped. Overall it's a quality sleeping bag, light weight, and offers much better size/warmth performance of any sleeping bag anywhere near the price. I've used mine for a number of years now and recently bought two more for friends, as it is better than anything found in German stores for anywhere near the price. Highly recommended for backpackers/trekkers who don't plan to sleep in temperatures much colder than 40F/5C (unless you have additional quality cold weather gear). A compression sack is necessary to further reduce the size; my medium sea-to-summit compression sack holds my sleeping bag, inflatable pillow, thermal underwear, beanie, gloves, warm socks, and a few other soft/compressible items, yet is still smaller than the sleeping bag is without a compression sack). As for a compression sack, I recommend Sea to Summit, as I've had mine for years and never had any issues.

Soft, warm, and well-made.neat stitching, no weird smell. Lightweight and packs small—great for school or trips. Fantastic value for the price!
