Hyperlite Mountain Gear 2400 Windrider Backpack

Selected as “Best Ultralight Pack” by Backpacker Magazine, the 2400 Windrider is HMG’s flagship ultralight pack and is a first choice for Appalachian Trail and long-distance hikers.  This 40 liter, 28.2 oz. (799 gram) pack is perfect for weekend trips, section hiking, or months on the trails where frequent re-supply points are available, such as the AT, the Long Trail, or the El Camino de Santiago.

Constructed from our Cuben/50d Poly hybrid-fabric, the 2400 Windrider is lightweight, durable and will be one of the most comfortable packs you’ve ever owned.  This pack includes a roll-top closure, Y-strap top compression, four side compression straps, an internal mesh hydration sleeve, hydration port, removable internal aluminum stays, sternum strap, and three external mesh pockets for added volume and storage - great for stowing snacks for the day, a water bladder, an extra jacket, or drying damp gear as you hike.

New features for 2014 include fully sealed side seams for improved water resistance, a double-reinforced 150d pack bottom, re-designed hip-belt pockets for improved utility, and extended hip-belt length for better wrap around support and improved weight transfer capability from the shoulders to the hips.

Recommended weight carrying capacity range of the 2400 Windrider is 20-40lbs and as with all HMG packs, a rain cover is not required, however we do highly recommend Cuben fiber stuff sacks to compartmentalize your gear and provide an added layer of water resistant security.
