Arcteryx men's Alpha SV Lampyre Men's Shell Jacket

Product Description

Ultimate Protection for Extreme Conditions
Built for those who challenge the most unforgiving alpine environments, this premium mountain shell is engineered to perform when everything else gives up. With rugged 100D GORE-TEX PRO ePE fabric, it provides unstoppable waterproof, windproof, and breathable protection—keeping you dry, focused, and climbing strong in the harshest weather imaginable.

Next-Generation Fabric Technology
The advanced 100D GORE-TEX PRO ePE membrane delivers maximum durability with a lighter, more refined feel. It’s completely free from intentionally added PFAS and designed for long-term reliability in extreme cold, heavy rain, and high-altitude exposure.

Enhanced Design Details
A discreet RECCO® reflector hidden in the hood enhances search visibility in rescue situations. Inside, multiple storage pockets give quick access to essentials—two dump pockets for gloves or headwear, plus a secure zip pocket to protect your valuables.

Performance Maintenance Tip
The new ePE membrane is thinner yet equally strong and waterproof as before. If the outer fabric appears to “wet out” more quickly, simply wash and dry to reactivate the water-repellent coating and restore full protection.
