Marmot Always Summer Sleeping Bag: 40F Down
Lightweight and super-packable for warmer-weather adventures.
If you spend more time falling asleep to the whisper of gentle summer breezes than the howl of winter winds, the Marmot Always Summer 40-Degree Down Sleeping Bag is the perfect combination of warmth, weight, and packability. It'll easily keep you comfortable down to 43 degrees, thanks to 650-fill goose down, and it won't turn you into a popsicle if it gets covered in morning dew when you're sleeping under the stars since the insulation's been treated with water-resistant Down Defender. As a bonus, it weighs under two pounds and packs down to the size of jacket, so it won't turn your small summer pack into a monstrous burden.
"Summer bag" isn't slang for "slopppily designed," though. The Always Summer has most of the features found in Marmot's cold-weather bags, like an insulated draft tube, face muff, and stretchy tricot baffles that let you move around freely while you're dreaming about pole vaulting. It also uses Marmot's trapezoidal footbox, which is wider in the toes and narrower in the heels, letting your feet move comfortably without the need for extra material and weight. The five-baffle hood's also warm without adding unnecessary bulk, and the locking drawcord let you seal up your bag tightly for a snug night's sleep.

Great for Lighweight Summer Backpacking
- Familiarity:
- I gave it as a gift but have feedback to share
Bought this item for my dad on his summer bike tour around Lake Eerie. It is super lightweight and with the help of a compression sack shrinks down to a size less than a nalgene bottle. Works great so far.

Get this if you want to look like a bird
- Familiarity:
- I've used it several times
Not a terrible sleeping bag and temperature rating is accurate. Bag is lightweight and fits into a very small size. Unfortunately, it sheds feathers like crazy, to the point where I refuse to use it anymore. I've used it a few times and each time I've emerged looking like a bird. Wish I could return it, but it's been too long.

Favorite bag for warmer nights!
- Familiarity:
- I've put it through the wringer
This bag is definitely a comfier bag than most. The 40D nylon ripstop fabric is a bit softer rather than the stuff covered in some DWR. I am 5'10" and have the regular that fits like a glove. May feel a bit tight to some but if you like feeling a bit more snug in your sleeping bags this is a great fit.

Fill less than expected
- Familiarity:
- I returned this product before using it
Like the lightweight of this bag & quality. The down filling is inconsistently distributed in the panels. Even after letting the down to puff up / out after storage!

A little narrow for me
- Familiarity:
- I've used it several times
I've taken this bag on a few hikes now. The quality is good, but I don't think I understood how narrow this bag was when I bought it. If you're someone who likes to move your legs around while you sleep then this may not be your bag.

Good!
- Familiarity:
- I've used it several times
Works great at temperatures around 40-60F. I'm 187cm and I went for the long version and I have lots of space in width and length, a bit too much even. Zipper is sometimes tricky to get closed from inside. Otherwise great bag!
