Hyperlite Mountain Gear Windrider 40L
Meet the Windrider 40L, the ultralight backpack built to handle nearly any adventure. Originally introduced in 2009, this pack has earned its reputation among thru-hikers and backcountry explorers alike for its remarkable combination of simplicity, performance, and durability. Designed for those who move fast and travel light, the Windrider 40L blends the iconic features of Hyperlite Mountain Gear’s original packs with modern upgrades, making it a trusted companion for multi-day treks and alpine missions.
At the heart of the Windrider is the new Dyneema® Woven Composite 3.9 fabric, offering exceptional abrasion resistance while keeping the pack incredibly lightweight and 100% waterproof. This cutting-edge material not only enhances long-term durability but also feels softer and quieter in cold weather—an important touch for comfort and stealth. The pack’s body is complemented by three large external mesh pockets that make organization easy and provide airflow to dry wet gear while you move.
Comfort and fit are equally prioritized in the Windrider 40L. The redesigned shoulder straps and sewn-through back panel follow the natural contours of your body, providing better weight distribution and reducing pressure points during long hauls. An integrated foam back panel and dual-density hip belt with zippered pockets give the support and convenience you need for full-day efforts. Adjustable sternum straps and removable aluminum stays further customize the fit and carry experience.
Functionality is deeply embedded in the Windrider’s design. A roll-top closure with vertical compression straps allows you to easily manage volume and maintain a stable load, while a Y-strap on top secures additional gear. The external daisy chains and removable compression straps give you total flexibility to carry tools like trekking poles or ice axes securely. Hydration is just as seamless, thanks to a simple bladder hang loop and hydroport for quick access on the move.
Whether you’re thru-hiking the Appalachian Trail, navigating alpine ridges, or exploring remote backcountry routes, the Windrider 40L is engineered to go the distance. With its durable materials, thoughtful upgrades, and weatherproof construction, this is a pack that adapts to your ambitions and excels in the world’s harshest environments. It’s not just a backpack — it’s a proven tool built for bold adventures.

Great for playful dogs
Size: Medium Set of 6
These are great! I unfortunately had to return them because my dog is 45 pounds and they’re too big for her. She couldn’t carry them constantly in her mouth. But the quality, colors, squeak, and bouncy effects are perfect for playful dogs or simply getting your dog to play more. I’m going to see if they have smaller sizes available. Great value too!

Not for chewers
Size: Medium Set of 6
Not for chewers, but I bet non chewers would like the. Good quality, bounce, fun color and texture. Fun while it lasted, but didn't last long with my 2 year old pitbull. We've been trying to find the replacement to his durable spiky ball that went down a sewage drain. Right now the Chuck-Its are the ones that last (minus just one)

Almost Indestructible!
Size: Medium Set of 6
My dog LOVES these balls, and it's all about the squeaker (which my husband hates). The size is great and I don't worry about it getting lodged in her throat. They are very durable too. We had one lone ball for YEARS and I forgot it ever squeaked, but it was still in tact. I searched for a replacement because I was so impressed with it. Very happy to have found it. I just ordered some for my son's dog too. The squeaker may eventually come loose, but it's worth the money to buy again!

The most durable and fun dog toy of all
Size: Medium Set of 6
Most durable and fun toy of all. The only thing that I have found that can destroy these balls is a lawnmower. Probably good for keeping teeth clean too.
