  1. Exactly like pictures and videos

    I was nervous to buy this bag because it was so cheap and I don't like buying on line, but this bag is great! It fits the temperature description and is super comfortable. I am a girl and decided to get this one instead of the women's on because it was more expensive. It's huge for me but is still super cozy (especially because I move around in my sleep). 100% would recommend on May 8th 2018

  2. Exceeded rating

    This bag kept me warm on about a 15 degree night, sleeping in my clothes and t shirt, also a hat to cover my baldness. Feet did get a little cold, but I put some boiling water in my Nalgene and threw it down there, problem solved, problem stayin' warm solved. Was able to wiggle and get comfortable. Draft collar let some air in, but hey, it was beyond the limits of the bag. Lesson learned. I'll keep this one for warmer trips and buy another for colder weather adventures. Also - bag got a little wet, turns out my Nalgene got a little wet and it transferred to the bag. Did not affect my comfort in the slightest, super forgiving bag. You guys make good stuff, keep it comin! on Jan 3rd 2018

  3. Understanding ratings...

    First off, I don't own this bag, but I do own other Kelty bags, including the Tuck 20. I saw the discount on this item, and then saw the poor review, so I'm responding to it.

    This is an EN 30 bag. In theory, that means that it will keep a warm sleeper "comfortable" at that temperature. Also, (EN ratings are based on a sleeper wearing one long underwear layer and a hat, and sleeping on a single one-inch thick insulating pad.)

    Men tend to sleep warmer than woman. So if you see a "comfort rating" that usually is the guide for a cold sleeper, or temperature rating for a woman.

    Realistically though, even if you're a man, add 10-20 degrees to the EN rating, and if you're a woman, add the same to the comfort rating.

    Also, any rating, is a just a guide, not a guarantee. Everyone's body is different, most people don't sleep with a hat on, or mid-heavy weight thermals. So if you plan on sleeping in 20-30 degree weather, get a 0 degree bag- more or less.

    Additionally, the slimmer fitting the bag, meaning the less extra space inside the bag, means the less air inside the bag that your body has to keep warm. If you're a woman and used a mans bag you might notice your feet get cold, because there is an extra foot of sleeping bag past your feet. The Tuck series are LARGE bags, designed either for people that don't like being restricted, or people that fit into the "Big & Tall" category. However, if you're an average size person, just wanting more wiggle room, the bag will be even more inefficient.

    I have the Tuck 20, and while I am average size, I use it during the winter backpacking, bc my dog will sleep in the bag with me, so she takes up the extra space, and neither one of us freezes.

    If you're new to things like this, REI online is a great resource for general questions and explaining things in laymen terms.

    As for this bag or other bags- Kelty makes amazing products, and I will always buy from them.

  4. Froze in this bag!

    I took this bag with me on a 3-night camping trip last weekend. The low was high 30s on the first night and low-mid 40s the next two nights. I went to sleep the first night wearing thermal pants and a shirt and woke up freezing. Had to put a pair of fleece pants and a fleece jacket on over the thermals and still stayed pretty cold. The next two nights I also slept in thermals and woke up cold again both nights, though not quite as bad as the first. The bag seems like it would be a nice 50 degree bag, but I can't imagine sleeping outside in anything colder than 50 degrees and staying warm. Certainly not a 35/30 degree bag! on Feb 28th 2017
