    • Warm, light, all the little flourishes
I generally prefer quilts to bags, but as I contemplate some solo trips in colder climes, a mummy bag seemed like a smart option. Because I tend to sleep hot and given the weight/compressibility of the different temperature ratings, I got a 15 degree rated long bag (I am 6'5"), my 30 degree quilt has taken me lower than its rating comfortably. I can't say I was thrilled with the sole yellow color option but oh well. The bag comes in a storage cell, and already Sea to Summit (who I have other gear by, I love their Evac bags) has me impressed. I try to preserve my down item's loft, but that means my camping gear storage area is draped in quilts and puffy jackets all willy-nilly. I love that this comes with a storage option not just for the trail (more on that) but also for at home. The bag itself is as light as you could hope for, and comes with a very elaborate lab analysis of the down. I can confirm it comfortably fits a taller person, I would even say you could get more that 6'6" in there. The double zipper is a boon for warmer nights to partially open the bag, and I like the snaps to attach a quilt, even mine from another brand can clip in. The cinch for tightening around the head and face is easy to use from inside the bag, at least to close it, loosening is a bit tricky. And it is toasty, though I haven't gotten to find its lower limit just yet. Under my guideline of the harder a piece of gear is to get in its stuff sack, the better and moat likely ultralight it is, this is quality ultralight gear. I do like that two of the snaps have snap buckles so you can really get a decent opening. You can really crank it down to compress it, and it relofted quickly after. All in all, I am pleased and impressed, and even the yellow is starting to grow on me. ... show more
