Product description is for Porter 4400 all models are available and specs are given below.


We stripped down, dialed in and beefed up our 4400 Porter Pack for passionate packrafters, mountaineers and multi-discipline adventurers. Though similar to our smaller versions, this ultralight pack has a wider circumference, is made from burlier material and has additional elastic frame sheets that offer greater load carrying capacity. Weatherproof your pack by using our Dyneema® Composite Fabrics (formerly Cuben Fiber) Stuff Sacks. Add a Porter Stuff Pocket for extra storage.
