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.

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!

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.

Very good

Nice bag. Got it with the right zipper to connect with my left zipper one for my lady. She loves it.

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!

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.

Slept like a baby

I've tried many sleeping bags and had an issue waking up in the middle of the night due to being cold. This sleeping bag has me sleeping like a baby

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.

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.

all I thought it would be

I got 3 of these for the family and we've already tried them out 3 times. the temp got down to 28, so I kept worrying about my kids. They were both super warm and slept like rocks!(We did have pads underneath)and I was pretty comfy myself! Great bag for the price- I only wish the zippers were easier to use (they get caught easily)- other than that- all good!

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 and classic sleeping bag will be your favorite for all your spring, summer, and fall adventures.
