Sleeping Bag Review: Sierra Designs Wild Bill/Rosa

Pinch me: Our favorite bag is also the least expensive.


Warmth The loftiest bag of the lot, with a no-exaggeration rating-I stayed toasty on a 20-degree F night in Canyonlands National Park.

Fit Roomy hood and interior dimensions strike the right balance between efficiency and toss-and-turn comfort.

Features We like the soft taffeta lining, the pillow pocket, and the integrated pad straps.

Shell The ripstop nylon shell with DWR finish repelled condensation and wind.

Women's model The Rosa is sized for women and sports a cozy fleece-lined footbox.

Price $99 is not a typo.


Bulk Warmth has its price. This bag is the bulkiest in the test.

Zipper It snags occasionally.

Price: $99
