## Description

Original ultralight backpack for shorter hikes from the legendary brand Hyperlite Mountain Gear. The Windrider is a backpack that thrives primarily on wet forest trails and rainy ridges. HMG relies on a simple, proven design and the best materials. The backpack is constructed from super durable, lightweight, and waterproof Dyneema® (DCH150) material. The black version uses an even more durable, but a few dozen grams heavier material.

Original ultralight backpack from HMG – ideal for shorter hikes for true fans of ultralight and thru-hiking.

## Proven classic from HMG

Windrider has all external pockets made of durable mesh with an elastic hem, allowing you to easily and quickly dry wet gear. Conversely, when it rains, water simply drains away. The backpack is also made of waterproof Dyneema and has taped seams, which is why it is the **perfect choice for trekking in rainy areas and humid conditions**.

The volume of 40 liters is best suited **for shorter hikes and weekend treks**. Thanks to the roll-top closure and two compression straps on each side, you can easily reduce the size of the backpack, making it useful even **for single-day mountain climbs**. If you want to undertake long-distance trails with the Windrider 40 backpack, you really need to have a well-tuned and ultralight gear list and the possibility to regularly resupply (every 2-4 days) along the way.

Backpacks from Hyperlite Mountain Gear are among **the most used on long-distance trails in the USA**, such as the Pacific Crest Trail and Continental Divide Trail, which, in our opinion, speaks for something. (This information is based on annual surveys on the [halfwayanywhere.com](https://www.halfwayanywhere.com/trails/continental-divide-trail/cdt-thru-hiker-survey-2020/#thru-hiking-gear) blog).

## Materials

Dyneema® fiber is a revolutionary material not only in the outdoor industry. With its remarkable strength-to-weight ratio, it is **the** **strongest fiber in the world**. Dyneema® fibers are 15x stronger than high-quality steel, lightweight, abrasion-resistant, waterproof, and resistant to UV radiation and chemicals.

The **HMG Windrider** backpack (available in both white and black) is constructed from hybrid composite Dyneema® fabrics—**DCH150** (170 g/m2), which is created by merging and laminating additional layers with Dyneema® fibers. This material excels in **high abrasion resistance, exceptional strength, excellent rip-stop properties, and impermeability to moisture**.

Although the material itself is 100% waterproof, stitching creates tiny perforations. While most (more than 90%) seams in the backpack are taped, it cannot be considered completely waterproof. For full protection against water and moisture, we recommend using the backpack with [waterproof dry bags](/c/gear/drybags-and-organisers).
