The $400 price tag for a 32-degree bag is steep, but the Mountain Speed 32 is made of top-shelf materials, offers amazing weight and space savings, super comfortable feel, and enough warmth to ride out the unexpected.        

Materials
Utilizing very soft flyweight fabrics, high lofting 850-fill down, and a stripped down design to provide essential functionality, the Mountain Speed weighs just a single pound and packs down to tiny proportions.

Features
As the company explains, “the performance mummy is cut slim,” which seems redundant but is actually accurate. The bag sports a profile as slender as a songbird’s sphincter, contributing to weight reduction, but also reducing the amount of fabric available to accommodate bigger frames or restless sleepers. Our 6-foot tall, 195-pound tester was challenged to do anything beyond lay on his back, zip himself in and wait for the alarm.  The target market for the Mountain Speed—lithe mountaineers and cross-country cyclists, among others—may not mind the dimensions, but definitely try it out on the shop floor before you take it home.   

A wider-than-expected footbox provides extra comfort, but otherwise, everything is minimized, including a small gauge zipper secured at the neck by a barely-there hook and loop tab, and a single draw cord for the hood.
