Sea to Summit Flame FMII Womens Sleeping Bag - Long

I love love love this sleeping bag. It's beyond comfortable. I'm had some of my most comfortable nights of sleep (not just camping, but in general) in this bag. I have the 25 degree version and it definitely hasn't disappointed when it comes to keeping me warm in cold temperatures.The ultralight spec is also very appreciated -- this bag comes in handy when backpacking because it's super light -- a lot lighter than the ultra quilts that many recommend. Personally, I move a lot in my sleep so I prefer the mummy option to the quilt.5/5 stars, highly recommend.

Bought this 35 degree bag to replace a very old 40 degree unisex bag that wasn’t ever very warm. Used the Flame for 2 nights when temp went to ~43 degrees and slept warm with the zipper open and my head bare most of both nights—so, this bag is warm. It fits 5’ me perfectly with plenty of room to sleep on either side or on my back + I love the extra fill in the foot box. I was also worried about the 10D shell and 7D liner with my 37# energetic dog sharing the tent—so far, no problems.I would prefer a full-length zipper so that it would have more versatility for use on warmer backpacks or thru hikes. I sleep cold but also have occasional hot flashes so the short zipper was almost a deal breaker. I will have to purchase a light-weight quilt for warmer hikes.I tried, ... MoreBought this 35 degree bag to replace a very old 40 degree unisex bag that wasn’t ever very warm.

I used a larger waterproof sack and compressed it further by stuffing other things into my pack on top of it. I also thought the storage sack was too small and bought a large cotton storage sack to use instead.

I bought the 15° bag. Used it two times in my backyard to double check temps before going to Grand Canyon (cold on the rim!) It is comfy and warm. I found it went to 30° comfortably for me. I added the down liner for colder temps, which worked down to 15° or so, with just a few cold toes (on a mat with 7+ r value), could go lower and maybe be a bit chilly. I am 5'7" /130 and decided on the long. I tried both, was really on the fence. I think I should have stuck with the regular, BUT I will say I can bring my knees all the way up in the long and that is surprising and pretty cool! It is lightweight and packs small. It's bigger than a water bottle tbh but not huge still, esp for a bag this warm. I would have liked the baffle to be bigger around my shoulders but it ... MoreI bought the 15° bag.

Zipper works great, no issues. The cinch for the hood is fine, little fussy to undo, esp if just loosening one side, but still not a big deal. Def recommend if you have the money. For the size and weight, it's a good product if you have the money.
