More info
Hyperlite Mountain Gear 3400 Porter - is 55 liter, 33 oz. (939 gram for M size) ultralight pack is fifteen liters smaller than Porter 4400 but includes all the same features including four vertical daisy chains for lashing paddles, snowshoes, or a helmet. This model also has great pack volume for traveling in areas where you need to carry a bear canister. 
With its streamlined design plus a multitude of attachment points, the Porter 3400 gives mountaineers, hikers, multi-discipline adventurers and day-tripping packrafters a variety of options providing the capability for trip-specific customization. 
The Porter 3400 includes fully sealed side seams and sealing behind all sewn-on pack features for improved water resistance, a more durable double-reinforced 150d pack bottom. Weatherproof your kit by using our Dyneema® Composite Fabrics (formerly Cuben Fiber) Stuff Sacks. The Porter Stuff Pocket offers extra storage.
HMG can custom fit this pack for skiers by adding reinforced fully-woven Dyneema® side panels, bottom and ski holsters. For customization please write us an email.

If you don't know which one would best meet your needs, here is a short comparison of HMG backpacks

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 Dyneema® materials with tape stitch lines. When used with ultralight Dyneema 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 Dyneema 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.

Size chart
  • 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.

Small38cm - 43cm15.0” - 17.0” 
Medium43cm - 48cm17.0” - 19.0” 
Large48cm - 53cm19.0” - 21.0”
Tall> 53cm> 21.0”

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.
