Hyperlite Mountain Gear Windrider 55L
Introducing the Windrider 55L an ultralight, high-capacity backpack built for those who venture far and pack smart. Since its debut in 2009, the Windrider series has become a trusted choice for thru-hikers, long-distance trekkers, and wilderness explorers who demand a balance of simplicity, performance, and durability. With its refined features and increased volume, the Windrider 55L is ideal for extended journeys where reliability and efficient gear management are key.
This pack is constructed with a new Dyneema® Woven Composite 3.9, an advanced fabric that delivers outstanding abrasion resistance while remaining extremely light and completely waterproof. It’s engineered to withstand rugged conditions while feeling softer and quieter in cold weather — perfect for stealthy movement and lasting comfort. Three spacious external mesh pockets make organizing and drying gear on the go simple and intuitive.
Comfort remains central to the Windrider 55L’s design. The updated shoulder straps and curved, sewn-through back panel are shaped to follow your body’s natural form, ensuring balanced weight distribution and reduced fatigue over long distances. A cushioned foam back panel and dual-density hip belt with zippered pockets provide essential support and convenient access to small items. Additional customization comes from adjustable sternum straps and removable aluminum stays.
Every detail of the Windrider 55L is crafted with function in mind. The roll-top closure with vertical compression straps keeps your load secure and protected from the elements, while the top-mounted Y-strap offers extra storage for bulky items. Daisy chains and removable side compression straps give you multiple options for attaching trekking poles, ice axes, or additional gear externally. The integrated hydration sleeve and hydroport ensure quick and easy access to water on the move.
Whether you’re thru-hiking a long trail, pushing into high alpine terrain, or packing for a week in the wilderness, the Windrider 55L is ready to go the distance. Its rugged materials, thoughtful design, and weatherproof construction make it more than just a backpack — it’s a dependable tool built for ambitious adventures in demanding environments.

Pretty Good
Color: Red Nylon Yellow Hotdog
The toy is good for a heavy chewer, but is very slippery. You may want to rough it up a bit before giving it to your dog so they can hold onto it.

WARNING - EXTREMELY SHARP AREAS
Color: Yellow Nylon Corn on the Cob, Color: Yellow Nylon Corn on the Cob
UPDATE: The 2nd one I ordered was exactly the same with the sharp parts in the same areas as the first one. I cannot stress enough that a few points are sharp enough to cut or badly scratch. So if you’re planning on putting some food on it so your pup can lick, this is not the product you want! This could still scratch or cut the gums if used as a chew toy too though. I was thinking about sanding the sharp points but then I have no idea if that exposes any chemicals somehow? Really wanted this to work out!
I took this corn on the cob toy out of the plastic to wash it and before I even got to the sink I realized there were several areas that are super sharp. A few sharp enough that could cut or badly scratch! It was sealed in a plastic bag and shows no signs of being used so this defect must happen at the manufactures level. I added a video showing how easily it snags a cotton ball, cotton pad and even a beanie. Please thoroughly check your item before giving it to your pup! I was so excited to put some smashed banana on this thing and give it to my guy and thank god I checked it first! I’m going to return it and see if a 2nd one is any better and I’ll update if it is or isn’t. Also, the super sharp spots were very hard to photograph which is why I added the video.
