Hyperlite Mountain Gear Windrider 40L

Meet the Windrider 40L, the ultralight backpack built to handle nearly any adventure. Originally introduced in 2009, this pack has earned its reputation among thru-hikers and backcountry explorers alike for its remarkable combination of simplicity, performance, and durability. Designed for those who move fast and travel light, the Windrider 40L blends the iconic features of Hyperlite Mountain Gear’s original packs with modern upgrades, making it a trusted companion for multi-day treks and alpine missions.

At the heart of the Windrider is the new Dyneema® Woven Composite 3.9 fabric, offering exceptional abrasion resistance while keeping the pack incredibly lightweight and 100% waterproof. This cutting-edge material not only enhances long-term durability but also feels softer and quieter in cold weather—an important touch for comfort and stealth. The pack’s body is complemented by three large external mesh pockets that make organization easy and provide airflow to dry wet gear while you move.

Comfort and fit are equally prioritized in the Windrider 40L. The redesigned shoulder straps and sewn-through back panel follow the natural contours of your body, providing better weight distribution and reducing pressure points during long hauls. An integrated foam back panel and dual-density hip belt with zippered pockets give the support and convenience you need for full-day efforts. Adjustable sternum straps and removable aluminum stays further customize the fit and carry experience.

Functionality is deeply embedded in the Windrider’s design. A roll-top closure with vertical compression straps allows you to easily manage volume and maintain a stable load, while a Y-strap on top secures additional gear. The external daisy chains and removable compression straps give you total flexibility to carry tools like trekking poles or ice axes securely. Hydration is just as seamless, thanks to a simple bladder hang loop and hydroport for quick access on the move.

Whether you’re thru-hiking the Appalachian Trail, navigating alpine ridges, or exploring remote backcountry routes, the Windrider 40L is engineered to go the distance. With its durable materials, thoughtful upgrades, and weatherproof construction, this is a pack that adapts to your ambitions and excels in the world’s harshest environments. It’s not just a backpack — it’s a proven tool built for bold adventures.
