Why We Like The Idlewild 30 Sleeping Bag

From the woods to the backyard, the Marmot Idlewild 30 Sleeping Bag offers us a comfortable night's sleep wherever we set up camp. It's an easy favorite of ours thanks to the tandem of a traditional semi-rectangular shape and high-loft Spiralfil insulation wrapping us in warm comfort through chilly temps. Soft-touch fabrics help us melt into a deep slumber, while the 3D footbox gives us room to kick out without getting tangled.


  • Classic semi-rectangular sleeping for cooler conditions
  • Soft, comfortable fabrics keep the feel plush
  • Spiralfil Recycled LT insulation is warm and eco-friendly
  • Full-length, locking zipper with draft tube traps heat
  • Anatomically designed footbox lets our feet roam freely
  • Soft-lined internal stash pocket keeps a headlamp nearby
  • Included stuff sack makes for easy transport and storage

Best bag ever used.

[This review was collected as part of a promotion.] Recently bought this bag and used it out at June lake. My girlfriend and I slept comfortably and warm the whole night. I’m 5’8” she’s 5’1” we had plenty of room to turn over if needed. Was honestly surprised how warm the bag kept us without it being zipped up all the way. Also my gf really loves the look of the bag. 10/10 for us.

So much good cuddle

[This review was collected as part of a promotion.] I do like this bag. It has very comfortable interior material that feels way better than other bags. Plenty warm, if you have a heater partner that bag is good down to some really low temps. Zipper is normal so ok. I do feel like it is missing something not sure what it is tho. I also really wish it came with an appropriate stuff sack not just the loose big bag.

Extremely comfortable

[This review was collected as part of a promotion.] I use this sleeping bag for all my camping on the coast (Oregon). It's super comfortable, soft, yet durable. Kept me nice an warm throughout those chilly beach nights and early mornings.

Great summer slumber solo bag

Bought two thinking they would zip together. They don’t. One way zippers that do not go around the bottom.

Great design

very comfortable and well designed. Love how there is more insulation on top than bottom. Comfy outer fabric. Warm for a 30 degree.
