Why We Like The Outdoor Research Helium Adrenaline 20L Day Pack

The Outdoor Research Helium Adrenaline 20L Day Pack is our ultimate companion during fast-moving, high-alpine adventures. The pack is crafted from ultralight, durable materials like Pertex Shield Diamond Fuse, which provides reliable weather resistance while we hike or run on technical trails. Its 20-liter capacity offers plenty of space for our essentials, with convenient pockets that stow trail snacks, a hydration bladder, and our phones. The breathable back panel and ergonomic shoulder straps provide all-day comfort, and the detachable waist strap provides extra support and stability.
