5400 ( 90L ) PORTER PACK



Ski Modifications *

Weight 1.4 kg
Dimensions 80 × 50 × 10 mm


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.

We can custom fit this pack for skiers by adding reinforced fully-woven Dyneema® side panels and bottom. Add $100 and allow three weeks for delivery.
