The padding balances low weight with insulation and offers an optimized pack size. A Pertex Quantum outer fabric is wind- and water-resistant, breathable, and highly scuff resistant. What Our Gearhead(R) Experts Are Saying:"On steep, windy ridge traverses with a loaded pack, the mesh-lined breast pockets let heat out whenever the pace climbed. The stretch inserts moved with every step and stayed breathable through the hardest stretches."
