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.

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).

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.
Customer Reviews
The Marmot Voyager 55 is a lightweight, compressible mummy-style sleeping bag designed for cool weather backpacking and camping. Customers appreciate the bag’s warmth, comfort, and packability, making it a solid choice when space and weight are at a premium.
Pros
- Provides warmth down to around 30-40°F, with an EN comfort rating of approximately 55°F
- Lightweight design packs down small, ideal for backpacking
- SpiraFil high-loft synthetic insulation offers warmth even if the bag gets damp
- Comfortable, roomy fit for average-sized adults
- Full-length YKK zipper allows easy ventilation and features anti-snag design.
Cons
- Some customers felt the bag ran a bit small, so larger individuals may prefer the long size.
- Not suitable for colder temperatures below the 30-40°F range
- A few complaints about the zipper snagging despite the anti-snag design
Overall Customer Satisfaction
Most customers are satisfied with the Marmot Voyager 55 sleeping bag, praising its lightweight design, compressibility, and warmth for cool weather camping. While a few users had issues with sizing or the zipper, most found it to be a reliable and comfortable option for backpacking when pack space is limited. The bag’s synthetic insulation is also appreciated for its ability to retain warmth in damp conditions. Overall, the Marmot Voyager 55 is a well-regarded choice for those seeking a balance of warmth, weight savings, and packability in a mummy-style sleeping bag.
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.
Mummy-style sleeping bags are smaller and lighter than conventional bags of the same temperature rating, making them the go-to style for backpacking camping trips. However, many people don’t care for how confining they are, and they won’t accommodate 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.
The two-way zipper and hood draw cords allow for various ventilation configurations, allowing you to selectively increase the airflow and make yourself comfortable in various conditions.

The ability of synthetic insulation to insulate even when damp is another plus for users in humid or wet conditions. Overall, the Marmot Voyager 45 offers good value and performance for budget-conscious backpackers.
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, 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.

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 has the ability to bounce back from compression, but it is 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 are smaller and lighter than conventional bags with similar temperature ratings, making them many people’s first choice for backpacking outings. But some people complain that they are too restrictive and 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 an insulated bag liner or at least another blanket would be smart.
