The Alpha SV Bib is your armor against ice, spindrift, wind, cold, and the kind of storms that test more than just your gear. Built with burly 100D GORE-TEX PRO ePE, it delivers maximum durability and stormproof protection while maintaining freedom of movement on steep terrain. Side-separating zips allow fast transitions without removing boots, and the low-profile design layers cleanly under a harness. In fact, every detail is purpose-driven for the most demanding alpine environments.
What's been updated: The Alpha SV Bib has been updated to 100D GORE-TEX PRO ePE, our most durable, waterproof-breathable protection, now even lighter and stronger than before—all while remaining free from intentionally added PFAS. A low-profile RECCO® reflector improves your searchability in emergency situations. Storage solutions have expanded to include two new harness-accessible pockets on the thighs and one centre front pocket.
Product tip: The new ePE membrane technology is lighter and thinner, but just as strong and durable as the materials we used before. You may notice the face fabric “wetting out” slightly faster in products with ePE membranes, but rest assured this does not affect the waterproofing of the membrane itself. If you notice the fabric wetting out faster than you’d like, simply wash the jacket and dry it to remove the oil contamination and bring the DWR back to its full power.
