Gear Review: Windrider 40 Backpack By Hyperlite Mountain Gear
Weighing just 30 oz and built from Dyneema, the Hyperlite Windrider 40 is a minimalist backpack for ultralight hikers. Here’s why it’s a top pick for thru-hikes, long trails, and backcountry adventure.
Hyperlite Mountain Gear Windrider 40 Review: Ultralight Simplicity Meets Serious Trail Performance
If you're all about going fast, light, and far, the Hyperlite Mountain Gear Windrider 40 is a pack worth knowing. Built from ultralight Dyneema fabric and designed with thru-hikers in mind, this pack strips away the fluff and focuses on what matters most—durability, load stability, and just enough organization.
The Windrider 40 is a favorite among PCT, CDT, and AT hikers because it walks that perfect line between minimalist design and practical usability. Between the roll-top closure, the external mesh pockets, and the bomber waterproof build, it’s a killer option for anyone diving into the ultralight world without sacrificing reliability.
What Makes It Stand Out
The Windrider 40 is a simple pack that does its job exceptionally well. It doesn’t have zippers everywhere or a million compartments to fumble through—but that’s kind of the point. It’s made for moving efficiently, with quick access to what you need and nothing you don’t.
The all-white Dyneema version is iconic, but it’s also available in black for those who want a stealthier look. And despite its minimalist vibe, the Windrider can still carry up to 40L of gear, with side and back mesh pockets that are great for wet layers, snacks, or even a tent fly.
