The Rab Men's Spark Jacket offers reliable waterproofing in a lightweight package that's fit for the alpine and other faraway places. Pertex Shield gives this 2. 5 layer shell highly rated waterproof breathable protection for active endeavors in wet weather, and fully taped seams enhance waterproofing by preventing raindrops and snowflakes from seeping through. Rab equipped the Spark with zippered underarms for ventilation, hook and loop cuffs, and a hem drawcord for a secure fit. The helmet compatible hood features a wired peak to stay out of sight and a roll down clip for stowable security. When the weather gets better, you can stuff the Spark in one of its A line chest pockets for compact packability.
