The Rab Bigline jacket uses a 3-layer Pertex Shield fabric rated to a 20,000mm hydrostatic head, built to hold up against spindrift, slush, and snow spray on long, committing descents rather than short resort laps. A relaxed, freeride-specific fit leaves room to layer up or add insulation once midwinter cold sets in, without giving up the mobility needed to move through variable terrain. A RECCO reflector adds a passive safety layer for off-piste and out-of-bounds days. What Our Gearhead(R) Experts Are Saying:"I stayed dry through a full day of variable snow that ranged from dry powder to wet slush by the afternoon, and never had to stop and vent because I was overheating instead. That balance is what separates a shell built for one storm from one built for the whole season."
