Porter 55



The Porter 55 faces eclectic gear closets and open schedules without fear! It’s the pack we recommend to adventurers who prioritize simplicity and functionality and don’t settle for one mode of travel. Ideal for weekend, section, or thru hikes where resupply points are less frequent and/or for equipment flexibility. When the extra volume is not in use, the top can roll down enough to make the overall size of the pack similar to the Porter 40, but that additional space can come in pretty handy when you need it.

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 3400 Porter Pack. Packaging may have either name but the product is identical.
