Do I need a separate rain cover or dry bags with this pack?

The main pack body is made from 100% waterproof woven Dyneema, so rain won't penetrate the fabric itself. For critical items like electronics or a sleeping bag, a lightweight dry bag inside adds redundancy at seams and closures, especially during stream crossings or sustained downpours.

How do I measure my torso length to pick the right size?

Measure from the bony bump at the base of your neck (C7 vertebra) down to the top of your hip bones (iliac crest). Match that measurement to the torso size chart for the pack. A proper fit keeps the hip belt on your hips and the shoulder straps in the right position, which matters for load distribution on longer trips.

Will the woven Dyneema fabric snag or tear on branches?

The 200-denier woven construction resists abrasion and punctures better than lighter laminated Dyneema fabrics. It's designed to handle brush, rocks, and repeated wear. While no fabric is indestructible, this material is built for rugged trail use without needing constant care.

Can I access the main compartment without unpacking everything on top?

This is a top-loading pack with one main body, so you access gear from the top opening. The three external mesh pockets provide quick access to items you need frequently, like water bottles, snacks, or a rain jacket, without opening the main compartment.

Which volume should I choose for a week-long trip?

Volume needs depend on your gear, season, and whether you're carrying food for the full week. The 55L works for many people on week-long trips with compact gear, while the 70L suits those carrying bulkier items, winter gear, or a bear canister. The 40L is better for lighter loads or shorter outings of a few days.

Waterproof backpack in woven Dyneema for multi-day treks and thru-hikes

Most backpacks treat waterproofing as an afterthought—a rain cover that flaps in wind, a coating that peels after a season, or the assumption you'll line the inside with plastic bags. That approach adds steps, adds weight, and stops working the first time a zipper leaks or a seam gives up. This pack starts with fabric that is waterproof all the way through, so rain never gets to your sleeping bag or spare clothes in the first place.

The woven Dyneema construction is the difference. Laminated fabrics use a film sandwiched between layers, which makes them light but vulnerable anywhere the surface abrades. Woven material distributes stress across interlocking fibers, so a scrape or puncture doesn't propagate into a tear. You get the waterproofing and low weight of Dyneema without babying the pack or wondering when it will fail. For someone putting in long miles on rocky trails, through brush, or across multiple seasons, that durability is what lets the pack justify its cost over a conventional nylon model that needs replacing every year or two.

This matters most if you've owned a pack that worked beautifully until it didn't—the frame that bent, the fabric that soaked through, the shoulder straps that dug in after day three. The Windrider is built for people who have learned that the lightest option isn't always the one that finishes the trip, and that a pack which keeps working is lighter than carrying a backup or cutting a hike short.

Good gift when

Backpackers covering long distances in variable weather
Thru-hikers who need durability without carrying extra weight
Anyone tired of packing everything in separate dry bags
People who put gear through rough terrain season after season

Skip it if You prefer a pack with more internal organization, multiple compartments, or a built-in hydration sleeve—this is a streamlined design with one main body and external mesh pockets.

The details

This internal-frame backpack uses a fully woven Dyneema construction that combines abrasion resistance with complete waterproofing, so you can carry gear through weather without relying on a separate rain cover or dry bags for everything inside. The main compartment seals out moisture while three external mesh pockets let you stash items you need quickly or air out damp layers as you walk.

The shoulder straps and sewn-through back panel distribute weight across your torso rather than concentrating pressure at a few contact points, which matters once you've been carrying a loaded pack for several hours or several days. The woven 200-denier fabric resists punctures and scrapes better than lighter laminates, so the pack holds up when you set it down on gravel, brush past branches, or lash gear to the outside.

Available in three volumes—40, 55, and 70 liters—to match different trip lengths and carrying styles. Four torso sizes let you fit the frame height and strap position to your actual measurements, which keeps the load stable and reduces hot spots on longer days. Mesh pockets are deep enough to hold a water bottle or fuel canister and sit low on the sides for easier reach without dropping your pack.

The fabric is 100% waterproof on its own, not through a coating that wears away. Rain runs off the surface, and the material itself won't absorb moisture or gain weight when wet. Seams are the only potential entry points, so keeping critical items in a dry bag inside adds a failsafe if you're crossing streams or caught in sustained downpours.

This is a pack built for routes where you're carrying days of food and shelter, not just a daypack with extra volume. The frame keeps structure under load, and the woven Dyneema means you're not choosing between durability and carrying weight that cuts into your mileage. If you routinely put a pack through rocky terrain, changing weather, or weeks on trail, this one is designed to keep working without needing replacement after a season.
