Product Description


The 3400 Windrider is a 55 liter, 32 oz. (907 gram) version of HMG’s flagship ultralight pack that was selected as “Best Ultralight Pack” by Backpacker Magazine.  Perfect for backpacking, mountaineering, section hiking, or winter hiking, the 3400 model has 15 liters of additional volume to comfortably hold all of your gear when 40 liters just isn’t enough.  With the extra volume this becomes an ideal ultralight pack for thru-hikers on the Pacific Crest Trail or the Continental Divide Trail where re-supply opportunities are less frequent.  The 3400 Windrider can also accommodate bear canisters vertically. 

Constructed from our Cuben/50d Poly hybrid fabric, the 3400 Windrider is lightweight and durable and will surely be one of the most comfortable packs you’ve ever owned.  The 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 for 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 3400 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
