Awesome bag

It's nice and thick. Well made. Two pounds heavier than a down bag. It's the lightest I found in synthetic bags with its comfort rating. I will use it during my bicycle touring. It packs down almost same size as my 40F bag, but much thicker loft once I take it out of its bag. I am happy with my purchase.

Perfect for Hiking!

This sleeping bag is exactly what every hiker needs. It packs down into a super compact size, which makes it incredibly convenient to carry on any hiking or backpacking trip. Despite its small size, it's impressively warm and cozy - perfect for cool nights outdoors. The quality is solid, and for the price, the value is unbeatable. Lightweight, warm, easy to pack, and affordable - highly recommend for anyone hitting the trails!

Amazing sleeping bag

This material is such great quality and I can tell it's going to keep me warm and comfortable. I am 5'9" so I am also glad I purchased the long sleeping bag rather than regular.

Great gift

I got this as a gift for my grand daughter, she loved it!!! So much that her mother wants to order one for herself. They tent camp and this bag meets all their needs

Awesome & keeps you warm in lower temps for sure

I'm travelling around the country, having left in mid November. I headed North first, through West Virginia and Ohio, and this bag kept me plenty warm even down in the 20's sleeping in either my car or at a campsite. I even woke up sweating from being too hot some nights. Now in Illinois & snowing, so had to move to motels until I get South again. Many bags profess to be good in low temps, but I believe this one lives up to its word!

Great 3 season bag!

Great 3 season bag! I purchased this for my son after he insisted on using my Marmot bag and I'm so glad he has his own! The same quality we expected at a great price!

Warranty

Having trouble with their Warranty Dept. Frustrating due to fact that the hood draw string was sewn into another the bag making it stuck in place. Still waiting.

Great value bag!

Great bag for all use cases. Can compress small enough to backpack, but not skimping on warmth and comfort! Durable zippers and cozy!

Perfect 3 Seasons Bag!

Great 3 seasons bag for those warmer nights! It is light, packs down small, and the synthetic does not bunch up like some down bags. I run warm, so this bag truly works for me down to 25°-30° F. The zipper is sturdy and no problems with snags. Very satisfied, Nice Marmot !

Happy Camper

We bought this for my son to replace his prior Marmot bag that he used as a child (the junior version). He absolutely loves this bag. It is warm, soft and easy to zip.

Better than down

Bought this bag for almost all my adventures in the Rockies. Dream bag really. Soft like down. Packs up small and light. Marmot's synthetic is absolutely amazing. I use thi bag almost year round!

My favorite sleeping bag!

This sleeping bag is great! Always keeps me warm, I loved the hooded top to keep my head warm when it gets cold. The color and inside design makes me happy. Always recommend !

Trestle-like bag bought in 1989

I purchased my first down bag in 1989 on a trip to Kittery Trading Post in Maine on a weekend free from graduate school. My now-husband ordered the mirror-image bag so that we could zip them together to keep me warmer during backpacking trips. We still have both bags and use them all the time, whether in the backpacking, or as a duvet during car camping. I've relofted mine twice now, both times with incredible customer service from Marmot.

Great sleeping bag

I bought this sleeping bag to go backpacking in Colorado. It more than performed. It is warm and lightweight and packed nicely in my pack. I wound up purchasing the same bag for my son.

Winter Staple

I have used a version of the bag for six years. Always keeps me warm. I wish it was a like lighter for backpacking, but other than that it is amazing. It is so comfortable and always keeps me warm. I have slept at 0 Fahrenheit or -18 Celsius. It has been great. For super low temps I pair it with a liner, but it never fails for comfort or warmth.

Cozy and spacious on those chilly nights

Great bag for those chilly nights! I run hot and have used this down into the 20s (F) with no issues. Spacious all over including feet and for side sleeping. The zippers are heavy-duty and zip well. Mummy head for the colder nights and the bag has a pocket placed conveniently. I also love how compact it gets while stored!

Long Bag

I'm 6'1 and the long bag works great. Really like the short zipper that opens on the non zipper side for a little extra room.

Marmot Trestles 30

The Marmot Trestles 30 is a great sleeping bag!!! We have a family of 6 and we all each use a Marmot Trestles 30. Recently we camped in Glacier National Park in a tent and we slept very comfortable!!! I would definitely recommend this to anyone!!

Super comfy and a great value!

Perfect for car camping in the high Unitahs. Great price and comfy. A bit bulky for long back trips, but great for a weekender with not too many long hikes.

Warm and cozy happy camper

I was very pleased with this sleeping bag. I took It with me to the Grand Canyon ( where it snowed on Memorial Day weekend ) and it kept me warm and cozy throughout the night. I appreciate the ability to unzip the bag on both sides down the torso area. The zippers are wonderful and very smooth, no snagging here. The bag is roomy and you can lay on your side and move your feet around without feeling confined. I am 5’2” and 127lbs for reference, I ordered the regular size length. I highly recommend this bag. I always run cold and slept like a warm and cozy baby throughout the night. Enjoy!

WARM

By Johnathon L.

Worth the money in every way. Crazy warm and comfortable at some of the coldest Pacific Northwest temperatures. Great buy!

This is a classic, all-purpose, three-season sleeping bag that has more than 40 years' worth of Marmot's outdoor knowledge. There's 35 ounces of premium Spirafil High Loft Insulation to provide more than ample protection on chilly nights. On warm summer evenings, the Trestle provides superior ventilation with its two zippers (one full and one quarter length), keeping your core warm while letting your extremities get some fresh air. This bag has an outstanding cost/value ratio- you won't find a better 3-season bag with similar features for a better price. A handy compression sack is included with the bag, and it's just as strong and durable as the bag itself. This reliable sleeping bag will be your favorite for all your spring, summer, and fall adventures.

Marmot Trestles Features

  • Add extra ventilation with the fold-down second zipper on warm nights
  • Anti-snag slider to reduce zipper snags
  • Marmot SpiraFil synthetic insulation is durable and compressible
  • Anatomical wrap-around footbox adds insulation and room for tired feet
  • Weave construction on top, blanket construction on the bottom
