Warmth
The Deviator is not the warmest jacket tested but it did provide impressive warmth-to-weight ratio and surprising wind resistance. The jacket’s minimalist construction and wicking Polartech® Power Grid™ augmented breathability so I never over-heated or stayed wet.

Fit & Comfort
Knowing that the Deviator’s form-fitting design is core to its functionality, I found the men’s medium somewhat tight through the middle, and chest pocket contents are very noticeable. Polartech® Power Grid™ is soft and flexible with no constriction points. The Deviator disappeared under larger mid-layers and shells—I forgot how I stayed so warm.

Features
The Polartech® Power Grid™ hood is over- and under-helmet ready. Streamlined hand-warmer pockets open into the insulated core, meaning hands enter a pocket of captured warm air. They also hold an adjustable waist drawcord and a keyclip. It has chin guard on the zipper and padded thumb loops. 

Quality
Shoppers considering the Outdoor Research Deviator Hoody may worry about such a light jacket keeping pace, but I found no reason for concern after a couple of months of consistent wear. The 7D ripstop on the front panel warrants extra care.

Weight
The Deviator Hoody was the lightest in the hybrid jacket test, measuring 10.9 ounces. Bonus: whether designed to or not, the Deviator packs easily into either of its pockets to the size of a softball.
