|Hyperlite Mountain Gear (HMG) is a designer, manufacturer and supplier of durable lightweight and ultralight outdoor gear. The idea for the company began 2 years ago when founder, Mike St. Pierre began experimenting with reducing his gear weight. An outdoor enthusiast, he would escape the city streets of New York and head to the mountains on the weekends. He learned about Cuben Fiber, purchased a small quantity and built a prototype. Thus, Hyperlite Mountain Gear was born.In late 2011, HMG was thrilled to be selected as one of the winners of a contest sponsored by Google and American Express in support of Small Business Saturday.

|HMG makes a wide variety of lightweight gear. We’ve put together a selection of what we believe to be the best of their products to launch the brand here in Portland:
The Windrider Pack is HMG’s smaller volume ultralight backpack. It weights a scant 28 ounces, an internal volume of just over 39 liters, and carries loads of up to 30 pounds comfortably (no really, we’ve tried).
The Ice Pack is basically the Windrider with climbing specific features, like a crampon reinforcement patch on the front, and ice clipper slots on the hip belt. It come in at 32 ounces.
We have two smaller day packs: the Summit Pack has some external strapping and stash points for adding on gear or lashing things down, and weights 11 ounces; the Stuff Pack has fewer external features and utilizes a slightly different fabric that drops the weight to 8 ounces. Both packs have no frame sheet or stays, so they are fully packable as summit packs.
All of the HMG packs are made of cuben fiber and utilize a roll-top closure that makes them waterproof (non-sumbersible).
Finally, HMG makes some ridiculously light stuff sacks. There are six sizes: Nano, Small, Medium, Large, X-Large, and Jumbo. Using the same Cuben Fiber material they use for all their gear, these stuff sacks are waterproof (non-submersible), lighter than sil-nylon and stronger than kevlar.
What is Cuben Fiber?
Cuben Fiber is a high-performance, non-woven, rip-stop, composite laminate developed in the 1990s by a nuclear weapons physicist and an aerospace composite engineer. Originally designed for use in world-class sailing, it is ideal for certain applications in lightweight and ultralight outdoor gear due to its unmatched strength-to-weight ratio.
Technically speaking, Cuben fiber is a laminated fabric made using patented technologies with unidirectional prepregnated tapes of in-line plasma treated fibers that are spread into mono-filament level films. In more simple terms, Cuben fiber is made by sandwiching Spectra or Dyneema polyethylene fiber filaments a thousandth of an inch thick, in various arrangements between thin outer layers of polyester film. The “sandwich” is then melded together in a high-pressure autoclave.
Cuben fiber is lightweight, highly durable, and is 50-70% lighter than Kevlar, four times stronger than Kevlar, and allows flex without losing strength. It is also less than half the weight of silnylon, has low specific gravity (floats on water), high chemical resistance, excellent UV resistance and is 100% waterproof.
