Hyperlite Mountain Gear Porter 4400 (70 Litre)


Incl. VAT

The Porter 4400 has been the ultimate in packrafting packs for a number of years now, more recently the 5400 has been gaining popularity due to its extra 15L capacity.

Used by more expedition packrafters than any other pack, from Alaska, to New Zealand to the Alps of Europe. The lightest weight, most durable, load carrying pack period.

HMG stripped down, dialed in and beefed up their 4400 Porter Pack. Built for passionate packrafters, mountaineers and multi-discipline adventurers. Though similar to 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 HMG Dyneema® Composite Fabrics (formerly Cuben Fiber) Stuff Sacks.

HMG can custom fit this pack for skiers by adding reinforced fully-woven Dyneema® side panels, bottom and ski holsters. Add €100 and allow four weeks for delivery.

Add a Porter Stuff Pocket for some extra storage on the outside of the pack.

How to Choose a Pack Size

Your torso length, not your height, determines your pack size. We recommend the following to determine yours:

  1. Tilt your head slightly forward to locate the bony bump at the base of your neck. (This is your 7th cervical (or C7) vertebra).
  2. Using a flexible tape measure, have someone measure starting at that spot and running down along the curve of your spine.
  3. 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.
  4. 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 (38 – 43cm torso)
    • Medium (43 – 48 torso)
    • Large (48 – 53 torso)
    • Tall (53 + torso)
  5. If your measurement falls right in between sizes (for example, if you have a 43cm torso, so you are right on the line between a Small and a Medium), we suggest you choose the larger torso size.
