Hyperlite Mountain Gear Windrider 55L

Introducing the Windrider 55L an ultralight, high-capacity backpack built for those who venture far and pack smart. Since its debut in 2009, the Windrider series has become a trusted choice for thru-hikers, long-distance trekkers, and wilderness explorers who demand a balance of simplicity, performance, and durability. With its refined features and increased volume, the Windrider 55L is ideal for extended journeys where reliability and efficient gear management are key.

This pack is constructed with a new Dyneema® Woven Composite 3.9, an advanced fabric that delivers outstanding abrasion resistance while remaining extremely light and completely waterproof. It’s engineered to withstand rugged conditions while feeling softer and quieter in cold weather — perfect for stealthy movement and lasting comfort. Three spacious external mesh pockets make organizing and drying gear on the go simple and intuitive.

Comfort remains central to the Windrider 55L’s design. The updated shoulder straps and curved, sewn-through back panel are shaped to follow your body’s natural form, ensuring balanced weight distribution and reduced fatigue over long distances. A cushioned foam back panel and dual-density hip belt with zippered pockets provide essential support and convenient access to small items. Additional customization comes from adjustable sternum straps and removable aluminum stays.

Every detail of the Windrider 55L is crafted with function in mind. The roll-top closure with vertical compression straps keeps your load secure and protected from the elements, while the top-mounted Y-strap offers extra storage for bulky items. Daisy chains and removable side compression straps give you multiple options for attaching trekking poles, ice axes, or additional gear externally. The integrated hydration sleeve and hydroport ensure quick and easy access to water on the move.

Whether you’re thru-hiking a long trail, pushing into high alpine terrain, or packing for a week in the wilderness, the Windrider 55L is ready to go the distance. Its rugged materials, thoughtful design, and weatherproof construction make it more than just a backpack — it’s a dependable tool built for ambitious adventures in demanding environments.
