Marmot Women’s Trestles 15° Sleeping Bag

- 15° rated, SpiraFil insulation
- Anatomical 3D footbox
- Locking YKK two-way zipper
Our take
The only true women's cut, and the warmest bag here by a wide margin.
Why it made the shortlist
The Marmot Women's Trestles is a 15 degree synthetic bag insulated with SpiraFil high-loft fiber and finished with a water-resistant shell. It has an anatomical 3D footbox, wave construction on top and blanket construction below, and a locking YKK two-way zipper.
The compression stuff sack is included, and the left-zip layout comes in a Long size.
It suits women who sleep on their side and want real three-season performance from a mountain brand. The footbox gives cold feet room to move.
What works
- Women-specific shaped design
- Footbox gives feet space to move
- Synthetic fill keeps insulating when damp
- Compression stuff sack included
Watch out for
- Costs far more than the others here
- Mummy-style cut limits sprawling
- The catch
- It is the priciest pick and the snuggest cut, so check the fit if you toss around.
