Ships in 1-2 business days | Based in Biddeford, ME | Est. 2010Hyperlite Mountain Gear's original backpacking pack *Formerly known as the "2400 Windrider"The Windrider 40 is the pack that super-efficient thru hikers and backpackers graduate down to when their kits are dialed, and the calories and fuel they need along the way are never too hard to find. Ideal for weekend or section hikes where frequent resupply points are available.There's a kind of classic image that comes to mind when you hear the word "hiking." Dense green and brown forests with meandering rugged root-strewn trails lead to awe-inspiring hill and mountain panoramas, and rivers and streams lull tired explorers to sleep at the end or strenuous but rewarding days. These are the environments where the Windrider takes flight.
