Gift For Partner:
We're all here because we hate the limiting shape of a mummy-style bag so I won't spend any time on that although I am VERY excited for the freedom to "be me" even while asleep. A major thing I would change about the design of this bag is that the hood cinch is on the OUTSIDE of the bag and very hard, if not impossible to adjust from inside the bag without opening it. I want to be able to adjust the opening while I'm in the bag, especially if I wake up chilly in the middle of the night. So that seems like a major design faux pas.
I LOVE the thermo-gills. As a warm sleeper, it made it so much easier for me to make a choice between the 15 and 30 degree bags. I love zipper pocket at the shoulder (big enough for my headlamp). It seems, based on other reviews, that they heard the complaint about a pricey bag not coming with a compression sack that has compression straps as mine did come with compression straps and packs to a completely expected size for the bag rating.
Also, I should say, I'm a woman and I bought the men's version of this bag for a few reasons. The biggest consideration for me was the women's version of this bag (Nemo Jam 15) is WHITE. A WHITE SLEEPING BAG? Come ON. It would be filthy and look disgusting within a few trips. For a company that prides itself on innovative design, boo to your women's bag, Nemo! Some things to consider if going this route: The length is identical between the women's long/men's regular but the men's adds an extra 2 inches of girth to the circumference of the bag. I'm hoping this doesn't make me colder. I have a silk liner to help, though and a fleece liner for very cold weather. Similarly, the women's bags tend to add loft where women get cold (hips, thighs, feet) so I'm hoping that I don't regret the lack of "women-specific" features and the fill weight difference between womens (1lb 11oz) and mens (1lb 5oz) doesn't make me regret my choice. I think the water-proof footbox will probably help at least in making the footbox seem warmer. I also prefer a left-side zipper and my partner was not in the market for a new sleeping bag so I didn't need to worry about the fact that we can't both buy men's bags if you want to take advantage of the bags zipping together.
I do resent the implication that women's bags ONLY come with a right zipper and men's bags only come with a left zipper. Because same-sex couples. And because I am a woman who likes left zippers.
All in all, the design features that I loved about this bag were enough to make up for the design features I didn't love and I look forward to this being my sleeping bag for a decade or more.
