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!

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 !

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.

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!

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!

Great!

I bought this for my daughter for a mid June camping trip in northern Minnesota. The temps were in the 50’s at night and she was very comfortable. This is her first mummy bag and she loves it so much she sleeps in it at home too!

Nice features and price was right

I'm not a huge fan of mummy bags, but needed something for spring/summer car camping and float trips. We're in a very humid region, so synthetic was my choice. I like the bag, despite it being a tight fit for me, at 5'9" and about 170 with some serious hips. However, it kept me warm on a couple of cooler nights and I really like the two zippers. Color is bright, but pleasant. At under $70, I felt it was a good purchase.

Buy this bag!

I was really hesitant about this bag as it’s not a go-to for backpacking due to its size and weight, but everyone talked about how comfortable it is, so I took a shot. I’m a side sleeper and like to rotate during the night, so mummy bags can be a problem for me. This was absolutely perfect! It was comfortable, warm during the rainy wet night when the lows got down to 40. I did wear merino baselayers, thick socks and a hat all night. For anything colder, I think an insulated sleeping pad and/or a liner would have kept me toasty. The compression bag that comes with it is awesome. Take your time with it to compress it, and it packs down amazingly. For the price, I couldn’t be happier.

Great Bag for a great price

This product is amazing! I have been sleeping in in outside in the middle of winter for two weeks now and have yet to get cold! It is a high quality product from the zippers to the seams and has many additional features that make it much more convenient than the average mummy bag!

Cozy

I used it in near Tahoe. Elevation 6700 ft, temp at night was 35 degrees. I wore a base and mid layer and was perfectly comfortable, even hot at times. I'm 6'3", 210 lbs and this bag was nice and long. Could have been a bit wider, but hey it's a mummy sack. The zipper was sometimes challenging but that is my only issue.
