Product Description


Ideal go-to pack for packrafters, yet also great for multi-discipline adventurers, extended trips in the backcountry, ski touring or winter travel when you just need more space, the Porter 4400 is a 70 liter, 37.6 oz. (879 gram) ultralight pack capable of carrying all your needs for the big trips, including your boat.

The Porter has a minimalist design with optional hip-belt pockets, a roll-top closure and four vertical daisy chains on the exterior of the bag; perfect for lashing paddles, snowshoes, helmets, or a variety of other gear for trip-specific adventures.

With our 100% waterproof Cuben/150d Poly hybrid fabric and the addition of fully sealed side seams in the 2014 model, the Porter 4400 is the best solution for packrafters due to the ability to lash the pack via daisy chains to the bow of the boat while keeping your gear dryer than any alternative on the market, particularly if used in conjunction with cuben fiber stuff sacks as an additional level of security.

The Porter 4400 has a wider circumference than our 2400 or 3400 versions, and includes a Y-top compression over the roll-top closure, two vertical compression straps, six side compression straps, removable shaped aluminum stays, an internal zipper pocket and a double-reinforced Cuben/150d Poly hybrid bottom.

New features for 2014 include fully sealed side seams for improved water resistance, a more durable 150d double-reinforced pack bottom, re-designed hip-belt pockets for improved utility, added hip-belt length and additional back panel frame-sheet allowing an increased carrying capacity of up to 60 lbs.

For extra external carrying capacity, add the Porter Stuff Pocket, an attachable external mesh pocket available in the accessories section of the website.

Note: This pack can be custom-fitted to carry skis upon telephone request.
