This 15K/10K duo uses 100 grams of PrimaLoft insulation in the jacket body and 60 grams in the sleeves, knees and seat of the pants. The fleece collar feels great against the chin, and the powder skirt attaches to the adjustable waistband of the nicely cut pants. Inner-thigh vents and reinforced cuffs add comfort and durability.

Jacket: $279 — Pant: $249
