Weather Resistance
With a weather-blocking shell outside and high-lofting fleece inside, the Baltoro Guide was ample armor against wind and snow whilst winter camping in the Sierra. And while its DWR-treated fabric can shrug off light rain, it is not waterproof.

Breathability
The slight air-permeability of Polartec’s Powershield fabric kept me comfortable even while fully zipped and charging hard in cold conditions, although humidity build-up was noticeable while working in more moderate temps.

Mobility
Long arms, smart patterning and stretchy textiles join forces to make the Baltoro Guide suitable for all sorts of deep-freeze gymnastics—this thing can move!    

Comfort
The shift it makes between on-the-go breathability and at-a-stand-still insulation is the Baltoro Guide’s single most comfort-inducing quality. It goes on comfy, and stays comfy.

Attention to Detail
Although they would have been small luxuries on a jacket built for thrashing about in cold weather, some users wished for more finely finished seams and lower-profile cuffs.

Value
Though it is somewhat pricey, the Baltoro Guide delivers huge performance that is well worth the cost.
