As light as air.
Do yourself a favor and trek with Hyperlite Mountain Gear's ultralight 4400 Windrider Backpack, because a week's worth of camping gear is heavy enough. Despite its ultralight weight, the Windrider is surprisingly comfortable and durable to handle long hikes. Its Dyneema Hardline suspension system includes spacer mesh foam at the shoulder straps, back panel, and waist belt, and there are supportive aluminum stays that you can remove for even less weight.
Hyperlite Mountain Gear made this pack out of the same Dyneema rope fabric used to catch climbers when they fall, so you know it will last for multiple seasons. The Windrider also has a roll-top closure and taped seams for reliable protection in wet weather. There's an internal sleeve styled for hydration reservoirs, and a loop designed for ice axes. The Windrider also has external mesh pockets, zippered waist belt pockets for valuables, and top and side compression straps for a secure load.

- Q & A
- Familiarity: I've used it several times
Besides being light as a light day pack, I appreciate its expandability. So far I have used it for short backpacking trips and also for 2 ten day treks in the alps and dolomites. A 35 to 40 liter pack would have worked but it was easy to collapse the top. Then when traveling again I was able to expand the pack to its full 70 L volume to accommodate my day pack with extra gear. Got rained on many days and nothing got wet. I missed having a brain at first but just bought a light zip stuff sack and dropped it inside. Items were just as accessible and organized as with a brain. Also took me a while to realize I didn't have to mess with velco, rolling and clipping the top - just folding it over and clipping the outer strap is sufficient, even in rain. I have climbed with it and it conforms and moves well. I have not carried a heavy load - maybe 30 lb max so far.
