Marmot sleeping bags are known for their incredible softness, warmth, comfort, and durability. And as a person who has been buying and using Marmot outdoor gear for over a decade now… Marmot builds their product to last a lifetime.
In fact, every Marmot product comes with a Lifetime Warranty, including their sleeping bags.
I can tell you from personal experience that my Marmot ski parka, bibs (I own several pairs for both outdoor recreation and cold-weather work), and various jackets and baselayer garments look and perform like they are brand new… even though I’ve been using some of them for well over a decade now, and going strong.
That’s why I have absolutely no problem recommending Marmot sleeping bags to anyone looking for a bag that will provide exceptional warmth, comfort, functionality, and durability for years to come.
Marmot Sleeping Bag Lifetime Warranty
Marmot gives you peace of mind with a hassle-free limited lifetime warranty on every product they make, including sleeping bags.
The warranty covers “defects in materials and construction for the practical lifetime of the product.”
Here’s the best part:
You don’t even have to register your purchase, you’re covered automatically — Simply contact the company and they’ll take it from there (they may require a receipt).
Best Marmot Sleeping Bags:
Marmot Ironwood 20-degree Mummy Lightweight Sleeping Bag
Expertly designed and crafted of premium materials, the Marmot Ironwood 20 is an all-around great performer, even in cold and damp conditions. Tip: If you don’t camp in weather that gets down to 20 degrees, then you can save approximately $50.00 by investing in the Marmot Ironwood 30 (see below).
Being lightweight and having a compact mummy style makes this sleeping bag a good choice for backpacking in cold weather. And its 650-fill-power down filling with Down Defender water resistance treatment makes it suitable for wet weather and damp conditions as well.
EN testing assures this sleeping bag can keep you warm in temperatures as low as 20°F. Its anatomically shaped footbox improves comfort by giving your feet a dedicated space where they won’t feel cramped or trapped.
Its ground-level side seams increase warmth and comfort by wrapping the front layer snugly around you. And its two-way zipper and hood draw cords make it easy to regulate heat in various conditions by allowing for a wide range of ventilation options.
The Snagless insulated draft tube on the full-length zipper that also has an anti-snag slider and a zipper garage means less frustration at bedtime and greater comfort through the night (a draft tube blocks air from blowing through the zipper).
The Marmot Ironwood 20 sleeping bag has a durable nylon shell for long service life and a breathable polyester inner lining that helps you sleep more comfortably.
I recommend searching Amazon or eBay for the best prices on the Ironwood 20.
Marmot Ironwood 30-degree Down Lightweight Sleeping Bag
The Marmot Ironwood 30 is a lightweight, compact mummy-style sleeping bag, which makes it a good choice for backpacking in cold weather down to around 30 degrees. Having 650-fill-power down filling treated with Down Defender for water resistance makes it great choice for damp camping conditions.

Tip: If you need something that keeps you warmer, then check out the Marmot Ironwood 20 above… it’s EN tested to provide comfort down to 20 degrees.
Your warmth and comfort are enhanced by this sleeping bag’s ground-level side seams, which wrap the front layer snugly around you. A wide range of ventilation options made possible by its two-way zipper and hood draw cords allow you to regulate your comfort level in various conditions.

Like other Marmot Ironwood sleeping bags, this one has a strong nylon shell for durability and a breathable polyester inner lining that helps you sleep more comfortably by letting excess moisture escape.
You may have noticed that the Marmot Ironwood 30 is very nearly the same as the Ironwood 20. But the Ironwood 30 is currently available for about a 1/3 less than the Ironwood 20, so you may prefer it if you’re OK with having a little less insulating power. And it also weighs a little bit less (960 grams for the 30° vs 1100 grams for the 20°).
I personally tend to get the best prices for gear like the Ironwood 20 on Amazon or eBay.
Marmot Voyager 55 Mummy Sleeping Bag
The Marmot Voyager 55 Mummy Sleeping Bag uses SpiraFil high-loft insulation, which is described as offering “maximum warmth and durability”. However, the consensus is that down is superior in both regards. On the plus side, synthetic fill is a cheaper material and that is reflected in the price of the Voyager 55, which is half the price of the Ironwood 30 above. That lower price is also because of the difference in temperature rating.
Mummy-style sleeping bags are smaller and lighter than conventional bags with similar temperature ratings. This is what makes them many people’s first choice for backpacking trips. The downside is they might make you feel a bit claustrophobic, and you can’t sleep on your side.
The Marmot Voyager 55 is EN rated to be suitable for temperatures as low as 55°F. The fact that it’s a warmer weather bag also means it’s lighter and less bulky — it can be compressed down to around 10″x6″, about the size a quart jar. That’s assuming you have enough strength and patience to stuff it back into the compression sack it comes in, which is not an easy task.
Various ventilation configurations result from its two-way zipper and hood draw cords, which allow you to make yourself comfortable in a range of conditions.
In my personal experience, Amazon and eBay typically offer the best price for bags like the Voyager 55.
Marmot Voyager 45 Mummy Sleeping Bag
Marmot uses their SpiraFil high-loft polyester fill to insulate the Voyager 45 Mummy sleeping bag. It’s inferior to down in terms of insulating value and ability to bounce back from compression, despite being described as offering “maximum warmth and durability”. But synthetic fill is cheaper than down, and that shows in the relatively low price of the Voyager 45.
Being smaller and lighter than conventional bags of the same temperature rating is what makes mummy-style sleeping bags the go-to style for backpacking camping trips. However, many people don’t care for how confining they are, and they won’t accommodate people who are side sleepers.
EN rated for temperatures down to 45°F, the Marmot Voyager 45 is not suitable for winter camping in colder regions. But it’s lighter and more compactable than extreme cold sleeping bags — it can be compressed down to about the size of a football and is a good choice if you are looking for a marmot backpacking sleeping bag. A helpful tip for stuffing a sleeping bag into its compression sack is to put the foot end in first so that air can escape out the head opening as you stuff it into the sack.
Various ventilation configurations result from its two-way zipper and hood draw cords, which allow you to selectively increase the airflow and make yourself comfortable in various conditions.
You’ll find some great deals for the Voyager 45 on Amazon and eBay.
Marmot Trestles 30 Mummy Sleeping Bag
The Marmot Trestles 30° Sleeping Bag is insulated with SpiraFil, which is a mix of relatively large, spiral hollow fibers for loft, and smaller polyester fibers for warmth and softness.
While not as impressive as high quality down in terms of insulating value per gram and ability to bounce back from compression, it is cheaper than down. So the Trestles 30° is cheaper and heavier, than the Ironwood 30 (1,380.0 grams versus 960 grams).
Being smaller and lighter than conventional bags of the same temperature rating is what makes mummy-style sleeping bags the go-to style for backpacking camping trips. However, many people don’t care for how confining they are, and they won’t accommodate people who are side sleepers.
EN rated for temperatures down to 30°F, the Marmot Trestles 30° may be warm enough for winter camping, but you’ll want to use insulated sleeping pads to cover the ground and have an insulated sleeping bag liner or even just an extra blanket available.
You’re likely to be able to make yourself comfortable in diverse conditions due to the various ventilation configurations that are allowed by the two-way zipper full-length zipper, an added partial-length zipper on the other side, and hood draw cords.
Check out Amazon and eBay for the best prices available for the Trestles 30.
MARMOT Trestles 15 Sleeping Bag
The Marmot Trestles 15° Sleeping Bag features SpiraFil insulation, which mixes relatively large, spiral hollow fibers for loft, with smaller polyester fibers for warmth and softness.
SpiraFil is inferior to high quality down in insulating value per gram and ability to bounce back from compression, but more economical. So the Trestles 15° is much less expensive than the Ironwood 20 and weighs a lot more (1,535.0 grams versus 1,100 grams).
Mummy-style sleeping bags being smaller and lighter than conventional bags with similar temperature ratings is what makes them many people’s first choice for backpacking outings. But some people complain that they are too restrictive, and they don’t allow you to sleep on your side.
With an EN temperature rating of 15°F, the Marmot Trestles 15° can keep you cozy while winter camping if the temps don’t get too far into the arctic territory. But be sure to use insulating sleeping pads beneath your body. Additionally, bringing along either an insulated bag liner or at least another blanket would be a smart move.
With its two-way full-length zipper, an extra partial-length zipper on the opposite side, and hood draw cords, you can be confident that you will be able to customize your comfort in a variety of conditions.
Amazon and eBay are my two favorite places to find great deals on camping gear like the Trestles 15.
