Porter 70



Make a big plan, and then go bigger with the Porter 70. For four-season missions where resupply points are less frequent, and bulkier gear or equipment is required, the Porter 70 can carry it all.

Hyperlite Mountain Gear designed the Porter for the expert ultralight backpacker or climber who moves fast, goes far and travels light. It’s ideal for shorter-duration adventures, where you’re sharing gear with your partner. Made from 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber), this backpack is highly durable and weather resistant. Use it with their stuff sacks for a nearly perfect waterproof kit.


Formerly known as the 4400 Porter Pack. Packaging may have either name but the product is identical.
