What weight Dyneema does Hyperlite Mountain Gear use for their packs?

Hyperlite Mountain Gear (HMG) is renowned in the outdoor industry for ultralight and durable backpacks that cater to the needs of adventurers, hikers, and mountaineers. At the core of our innovation lies the use of Dyneema, a cutting-edge material with extraordinary strength-to-weight ratios.  Dyneema, also known as Dyneema Composite Fabric (formerly Cuben Fiber), is a high-performance material that has revolutionized the outdoor gear industry. It is an ultra-high molecular weight polyethylene (UHMWPE) fabric known for its exceptional strength, minimal weight, and resistance to abrasion. Dyneema is significantly stronger than steel on a weight-for-weight basis, making it a top choice for manufacturing lightweight yet robust gear.We have embraced Dyneema as the main material in our backpacks, harnessing its remarkable properties to create packs that excel in both strength and weight savings. Hyperlite Mountain Gear offers a range of backpacks designed for various outdoor activities. The company utilizes different weights of Dyneema to meet the specific demands of each pack.  

50D Dyneema

 We often use 50-denier Dyneema for many of our backpacks. The "D" in "50D" stands for denier, which is a unit of measurement for the linear mass density of fibers. In practical terms, 50D Dyneema is known for its remarkable balance between weight and durability.Backpacks, like the Southwest, Windrider, and Junction, feature 50D Dyneema in their construction. These packs are suitable for a wide range of outdoor activities, from multi-day hiking trips to extended backpacking expeditions to thru-hiking. The 50D Dyneema provides a robust and durable shell while maintaining a lightweight profile, ideal for those who need a pack that can withstand rugged terrain and challenging conditions. 

150D Dyneema

 For those seeking even more durability, we offer packs with 150D Dyneema. This heavier-weight Dyneema is designed to handle the harshest environments and the most demanding outdoor adventures. Our 70L backpacking packs are a few examples of backpacks that utilizes 150D Dyneema. This weight of Dyneema is designed for long trips or expeditions where you need to carry extensive gear and supplies. The 150D Dyneema ensures that the pack can endure extreme conditions, from alpine mountaineering to thru-hikes. 

375D Dyneema

 At the upper end of the spectrum, we use 375D Dyneema for some of our packs. This Dyneema weight offers the ultimate combination of durability and performance. The Hyperlite Mountain Gear Prism is one such pack that utilizes 375D Dyneema. This pack is designed for ice climbing and other technical alpine pursuits, where the conditions can be particularly harsh.
