Light, Cuben Fiber 70 Liter pack

Hyperlite combined aggressive attention to detail with extensive backcountry river usage to strip down and dial in the 4400/70L Porter specifically for passionate packrafters and multi-discipline adventurers. However, the daisy chains allow you to customize your pack for any adventure, and this has become a favorite pack for mountaineers as well. Though similar to Hyperlite's smaller versions and still minimalist, this ultralight pack has a wider circumference, is made from burlier material and has additional elastic frame sheets that offer greater load carrying capacity. With four vertical daisy chains, three side compression straps per side and a Y-top compression strap across the top of the 4400 Porter can carry ropes, snowshoes, ice axes, a PFD, helmet or anything else you may need to lash to the pack. Also consider the attachable Porter Stuff Pocket accessory for added exterior storage. Made from 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber), the 4400 Porter is highly durable and weatherproof.
