Beginning in 1995, Arc’teryx has worked intimately with GORE-TEX fabric technologies. Their partnership has produced some of the most waterproof, windproof, and breathable jackets in the outdoor gear world.
To one degree or another, all Arc’teryx jackets are waterproof. Depending on the activity, some people prefer less waterproof jackets, as they’re typically more breathable (think Beta SL Hybrid, a perfect trail-running hardshell). Add to this the fact that all their jackets are treated with a water-repellent finish. Always check the specs online or on the product tag for more information.
