Marmot Trestles 30 Mummy Sleeping Bag Features & Benefits

You may be thinking that all sleeping bags are created equally. However, this couldn't be further from the truth. The features and benefits of the Marmot Trestles 30 bag assert that this sleeping accessory (read: necessity) is a cut above the rest.

1.  Portability

We know what you're thinking…. “Duh! It's a sleeping bag, so of course it's portable!” As we mentioned earlier though, not all sleeping bags are created equally. Immediately the Marmot Trestles 30 Bag sets itself apart.

Yes, most, if not all, sleeping bags roll up to fit into their corresponding sack. However, this doesn't mean that all sleeping bags are compact or easy to carry. Marmot is though! At only 3 pounds, the heavily insulated bag surprisingly doesn't add much weight to your load. While it can be attached to your pack, it may also fit in a bag. The 10.5L pack volume condenses the bag into a manageable and portable sleeping companion.

For trekkers on the go with little space and weight distribution to spare, the Marmot Trestles 30 offers a solution. Reviewers note that when packed into its compression sack, the bag measures about 12″ long by 8″ in diameter. This allows the sleeping bag to easily be hanged from your pack or stuffed inside with everything else. Furthermore, competitors such as the North Face Aleutian sleeping bag didn't compact as much as Marmot's bag. Thus, it's clear why the Marmot Trestles 30 is a fan favorite.

2.  Warmth

30 degrees sounds a bit chilly for outdoor sleeping. Marmot steps up to the plate and knocks this challenge out of the park; it's made to retain body heat. The Marmot Trestles 30 presents itself as a true outdoor necessity for nature lovers. Never again will you wake up shivering and wondering why you even brought a sleeping bag at all. Marmot Trestles 30 wants to snuggle you to sleep and keep you warm all night!

As you may have noticed, the name of the bag includes the word “mummy.” This speaks to the well-thought out design of Marmot. With a hood and zippered closure (so you can still breathe of course), the sleeping bag definitely delivers in its attempts to wrap you up like a mummy. If you're looking for plenty of room, this might not be the sleeping bag for you.

Coupled with this design, Marmot's SpiraFil high-loft insulation ensures the retention of heat in temperatures as low as 30 degrees Fahrenheit. The unique blend of hollow and polyester fibers, as well as a European Norm rating back this up.

That's not all though! A combination wave construction gives sleepers warmth and space on top, while enveloping them in a soft blanket sensation on the bottom of the bag. The aforementioned SpiraFil insulation marries with the wave construction to ensure you don't shiver all night, without making you sweat bullets either.

The full-length locking YKK two-way zipper allows sleepers to cocoon themselves off from the outside world. However, should things get a bit too toasty in your Marmot Trestles 30 bag, there is a secondary fold-down zipper for ventilation.

No matter what conditions you plan to sleep in, Marmot Trestles 30 plans to keep you comfortable and tucked in all night!


3.  Built to Withstand Everything

By now you have probably begun to see how great the Marmot Trestles 30 Mummy Sleeping Bag is. If you aren't sold yet, it may help to know that this sleeping companion is built to withstand not only the elements, but also everything else.

Marmot designed this bag of 70D 100% embossed polyester. While synthetic in nature, this aspect allows for an added level of moisture resistance that other competitors do not have.

Quality stitching, zippers, and straps ensure that the sleeping bag maintains its integrity while also standing up to the wear and tear of trekking and camping. Although Marmot causes consumers to spend a bit more up front, the cost-benefit analysis supports the evidence — the Marmot Trestles 30 Mummy Sleeping Bag is built to last!

What Travelers Are Saying About this Sleeping Bag

We honestly had a difficult time finding disadvantages of the Marmot Trestles 30 bag. Reviewers left glowing comments and reviews, bolstering both the reputation of Marmot and the experiences of outdoor enthusiasts.


  • plus Mummy style, wave construction, and SpiraFil insulation make the bag suitable for sleeping in temperatures as low as 30 degrees Fahrenheit.
  • plus Keeps you warm without making you sweat
  • plusLightweight, compact, and portable


  • close Zippers snag at times, however they free themselves with ease.

The evidence suggests that the Marmot Trestles 30 bag is a cut above the rest. While there are some minor issues with zippers snagging, the overall design and function is neither impeded nor rendered a fatal flaw. From campers to hikers and even military members, this bag has provided warmth and comfort that is unmatched by other brands.

Great for Summer Backpacking

This is a long lightweight bag suitable for summer backpacking. The bag comes with a compression sack that when cinched up turns the bag into a neat package that measures about 12” long x 8” in diameter with a weight of 3 lbs 7 oz. The sack has cinch straps on 4 sides, a drawstring closure, and a handle strap on the end. The bag itself has a zipper opening on the left side that runs the length of the bag and a shorter one on the right just around the head area.

There is a hidden zippered pouch on the inside of the bag near the chest. The hood area is closed with a drawstring. There are elastic loops on the outside area near the feet for hanging to dry. The bag provides plenty of room around the middle for turning. Fabric on the lower side of the bag has a slight texture to it to help prevent sliding. The bag was made in Cambodia.

Lightweight and Long

It is light weight for carrying and long enough for tall individuals. The bag is a great choice for 3 season backpacking when you know it’s not going to get too cold. We tried the bag and found that it was just warm enough for us at 60 degrees F. Overall, this is a nice lightweight bag, easy to carry, and plenty warm for men in warmer climates or for warm season backpacking.

Holds Up Throughout Dry Cycles

Throughout several wash and dry cycles, this sleeping bag has kept its form and the filling hasn't bunched up or shifted. The bag is comfortable and warm, as the rating is EN rated for the 30 degrees. We’ll say that since it's so packable, it doesn't offer a ton of padding against hard ground – you'll obviously still want a mat underneath you.

Mummy Hood

The mummy hood wraps up tight around your head to the point where you could have just your nose and mouth exposed if you want. There's an internal “stuff” pocket for valuables, which is also nice. As for the stuff sack, it's good, but it's a bit hard to get the bag into it by rolling it. But, once it's in, the straps compress it in all directions, not just around it. We wish it had a full cover over the opening, but it only has a little flap. That said, between the flap and the straps you can get it so that the opening is very small.

Alternative Sleeping Bags

If Marmot isn't your cup of tea, there are plenty of similar alternatives available. We've collected a few of our honorable mentions for you to consider.

Kelty Tuck Sleeping Bag
