Hyperlite Mountain Gear 4400 Porter - 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. (1106 g in M size) ultralight pack capable of carrying all your needs for the big trips, including your boat.
The Porter has a minimalist design with 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.
The Porter 4400 has a wider circumference than 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 150D Dyneema® hybrid bottom.
For extra external carrying capacity, add the Porter Stuff Pocket, an attachable external mesh pocket. Weatherproof your pack by using Dyneema® Composite Fabrics (formerly Cuben Fiber) Stuff Sacks.
Hyperlite Mountain Gear manufactures a line of ultralight backpacks designed for everything from a quick day trip to an extended expedition. HMG backpacks are made of 100% waterproof Cuben Fiber materials with tape stitch lines. When used with ultralight DCF stuff sacks, their gear provides a rainproof system for your excursion. Combined with ultralight shelter systems, you will feel like you can fly. Cushioned shoulder straps and hip belts, padded lumbar support and shaped aluminum stays, provide a super-comfortable fit. HMG lightweight Cuben Fiber packs have been specifically designed for backpacking, mountain climbing, and ice climbing, but are suitable for cycling, pack rafting, day hiking or just getting around town.
How to Choose a Pack Size
Your torso length, not your height, determines your pack size. We recommend the following to determine yours:
Tilt your head slightly forward to locate the bony bump at the base of your neck. (This is your 7th cervical (or C7) vertebra).
Using a flexible tape measure, have someone measure starting at that spot and running down along the curve of your spine.
Place your hands on your hips so you can feel your iliac crest, which serves as the “shelf” of your pelvic girdle. (It’s the first hard thing you feel when you run your fingers down from the sides of your ribcage.) Position your hands so your thumbs are reaching behind you.
Have your friend finish measuring at the point where the tape crosses an imaginary line drawn between your thumbs. This distance is your torso length.
Small (15.0” - 17.0” torso) -> 38cm - 43,18cm
Medium (17.0” - 19.0” torso) -> 43,18cm - 48,26cm
Large (19.0” - 21.0” torso) -> 48,26cm - 53,34cm
Tall (21.0”+ torso) -> 53,34cm
If your measurement falls right in between sizes (for example, if you have a 17.0” torso, so you are right on the line between a Small and a Medium), we suggest you choose the larger torso size.
