Look at you go, Marmot....
[This review was collected as part of a promotion.] Great bag. I'm glad Marmot is caring on the Trestle program. This is not my first Trestles bag, and definitely won't be my last. Being 6'1" is tough and this bag (long) doesn't feel like there is TOO much extra material and that they thoughtfully sized this bag properly. Super warm and easy to unzip in the middle of the night if you need to get some air. Sometimes the hotdogs, beans, and S'mores keep talking.... very good weight to warmth ratio.

Good size
I am 6 feet and this fits perfectly. It is very cozy even though it still rolls up into a small pack!

Recommend this sleeping bag
“I finally had a chance to use this sleeping bag and was thoroughly impressed. It was very roomy and kept me warm throughout the night. I was pleasantly surprised by how lightweight yet durable the fabric is. Rolling it up and fitting it back into the storage bag was a breeze—super convenient!”

Great quality
This sleeping bag has been excellent. The weight is perfect for small backpacking trips and it was very comfortable. It seems very durable so far and fits me well which is hard to find for my height.

Cozy as a burrito
Took this 20-degree synthetic sleeping bag into the wild, expecting to freeze like a sad granola bar. Instead? Toastier than a squirrel in a sauna. Zipped myself in and immediately forgot about the cold, my regrets, and the raccoon watching me eat trail mix. Only downside: getting out of it in the morning feels like breaking up with the coziest relationship you've ever had. 10/10 would hibernate again.

Awesome sleeping bag!
Love this sleeping bag! It’s super lightweight (I would be happy to take it backpacking) and cozy, it will definitely keep you warm. The pocket inside is a must and the zippers are super easy to get to and I didn’t have any problems with them catching on the fabric. I definitely recommend this!

Fantastic Sleeping Bag! Highly recommend!
Tried out the new Trestles Elite Eco Series and was highly impressed with it's comfort and warmth. Fantastic that it compresses down so tightly and is so light. Both my husband and son enjoyed it and we plan on purchasing the kid's one specifically for our future Cub Scouting adventures. Giving this product an overall 4 stars. While it is comfortable, our only critique is that it could be "wider". There is an extra-wide option, which we didn't get, but will in the future. The sleeping bag performed as expected and this critique is only to improve upon the existing comfort and amazingness of this sleeping bag.

Best bag I've had in years!!
This is a great general cold weather sleeping bag. I used to have a NEMO bag but I recently replaced it with this Marmot bag, and it is always something I look forward to climbing into each night when in the backcountry. The zippers are smooth and practical, and don't dig into my side at night. It is lofty and light, and extremely warm. The synthetic fill and shell don't get smelly when on long trips and dry very fast. It is also suitable in non-winter weather, as when opening it up it still stays warm but allows you to control warmth.

AWESOME SLEEPING BAG
I’m super impressed with this sleeping bag! Designed for cold weather, I expected it to be bulky and heavy, but it’s the complete opposite, this bag is sleek and very lightweight. The Trestles Elite Eco 20 provides excellent warmth for winter conditions while remaining versatile enough for use in cooler temperatures. In addition to its impressive insulation, this bag is packed with thoughtful features. The built-in headrest adds extra comfort and support, making it even cozier for a good night’s sleep. Plus, the functional zipper works seamlessly from both the inside and outside, making it easy to adjustment without hassle. It’s easy to store, incredibly comfortable, and offers outstanding value for the price—a great investment for any outdoor enthusiast.

Marmot Trestles Elite - Good Buy!!!
This Marmot Trestles Elite is very light weight, similar to a down bag. It was not hard to get into the stuff sack that came with it. For the quality, the price is excellent.

Hi. I have an Angel fire wm's sleeping bag and wonder what sleping bag it could go with for my long man to zip together with mine? The opening is on the right side of mine.
