    It's never too cold for camping.

    Summer nights in the alpine can get chilly and shoulder season sleeping is reliably brisk, but Marmot's Never Winter 30-Degree Down Sleeping Bag will keep you warm through all your spring, summer, and fall adventures. Not only is it packed full of 650-fill down that's been treated with a water-repellent Down Defender treatment, but Marmot made the shell from tough and lightweight nylon that's been treated with a DWR coating to keep tent condensation and spindrift at bay. The Nautilus multi-baffle hood and anatomic wrap-around footbox trap warmth in key places, while the ground-level side seams prevent heat from escaping and cold from creeping in through the floor. Marmot also hooked up a snag-less draft tube to stop cold from sneaking in through the zipper and included an internal pocket for stashing a midnight snack or headlamp.

    Keeping it Light

    • Familiarity: I've used it several times

    I'm quite impressed how this bag handled the cold. The first time I put this to the test, I wasn't certain what temperature it would get down to but knew it was about below freezing or so. This bag did it and I can say I still have all my toes! Packing it in was super lightweight not even knowing there was a sleeping bag in my pack. It was sooo nice! Really good call in the seams and zippers not being directly next to you but off set so there are no cold zips touching you during the night. As usual, the anti-snag zippers don't really work - I mean they do a better job but I wouldn't call it anti-snag proof. Not complaining, solid bag over all.

    Nice bag but wouldn't buy again

    • Familiarity: I've used it several times

    I've been using this sleeping bag for two years in many different conditions. At Patagonia (summer season) was the first which I felt close to its limit, I was sleeping on a REI Air Rail pad + a cheap EVA pad under the tent. I also took it to Spain's highest mountains on winter, there I had to cancel the approach because it was too cold for me to sleep in.
    This bag has always leaked a bit, sometimes just a little but sometimes I wake up covered in down.
    Last weekend I went up to the mountains and I was about to be cold on 40 degrees weather, I was a little disappointed. Some areas barely seem to have filling, maybe the down was poorly distributed after packing?

    I'm going to the glacier park early September and I'll have to buy a warmer sleeping bag because I want to make sure I'll be warm. I'd say this bag is comfy above 40s

    Nice bag but wouldn't buy again

    Great bag, great value!

    • Familiarity: I've used it several times

    Three day bikepacking trip on John Wayne Trail. I'm a cold sleeper, so I like to layer up.
    First night was cool, and I wound up unzipping in the middle of the night. Second night, gear got wet. Damp and mid thirties. Heavy rain on tent. Bag was toasty, I slept with down jacket and tights.
    Great bag, Stuffs small, packs light. Like most bags, you have to pay attention to zippers. Just take your time and don't force anything!
    Highly recommend!

    no frills warmth

    • Familiarity: I've used it once or twice and have initial impressions

    Used with a z-lite folder. Kept me warm in my tent in damp/rainy conditions with temperatures in the high 40s. The fit was slightly tight in the shoulders. Could have used a deeper pocket to store my phone, but other than that very satisfied. Compresses down very well and is very light as expected. Will be using this bag for warmer backpacking trips. I am 5'9

    Light weight and very warm

      Let me start by saying Inhave not had the chance to try this bag at the lower end of its temp rating yet. So far it seems like a great bag. Very light yet once you open it up it gets very lofty. I plan to take it on a section of the AT near the end of october, that should be a good test for it. I have one minor complaint. My marmot trestles actually came with a better compression sack. So i did have to order a compression sack for it. I only carry a 48L pack so space is a commodity.

      Light and warm.

      • Familiarity: I've used it several times

      Bought this as a gift for a friend whose sleeping bag mysteriously disappeared after a weekend camping trip. It's the same one he had before, and he loves it. It's been warm enough for chilly nights in the mountains and doesn't leave him overheating during late spring desert trips, and it packs down really small for backpacking. His old bag was a few years old already and had plenty of life left in it when he lost it, and this bag seems to be just as well made as the previous version. It's not overly roomy, but that seems to be a fair tradeoff for how light and packable it is.

      Welcome to cozy country

      • Familiarity: I've used it several times

      Before this sleeping bag my attitude was that “just grab whatever sleeping bag. they all work the same.” my opinion has shifted drastically since scooping up this bag. this is my favorite sleeping bag i’ve owned. keeps me warm on the ground or in a hammock. The material is really comfy. Helps you drift away into a dream world even when you’re trying to sleep in a noisy wind storm. Packs down super small and the down doesn’t leak out like other bags i’ve used in the past. highly recommend this product to anyone that's feeling indecisive about what bag to snag.

      Great Bag, Haven't been cold yet

      • Familiarity: I've used it several times

      I have had this sleeping bag for a few years now, and I really love it. Packs up really small and is still very warm! I would highly recommend this bag to anyone.
