Built for MTB, Moto, Snow, and Big Days Outside

The Defender 15L Hydration Backpack is built for riders who need more than a basic pack. Designed for mountain biking, moto, snow, and all-day trail adventures, it gives you the storage, hydration, protection, and no-bounce comfort you need when the ride gets rough.

With 15 liters of storage, an included 2L hydration bladder, removable spine protection, and a custom Send It harness system, the Defender is made to carry your essentials without shifting around every time the trail gets rowdy.

Why Riders Choose the Defender 15

A good MTB hydration backpack should do more than just hold water. The Defender 15 is designed to keep your gear organized, your hydration close, and your pack stable when you’re climbing, descending, jumping, hiking, or hauling through rough terrain.

The removable spine protector adds an extra layer of protection for aggressive trail riding, while the no-bounce harness helps keep the pack locked in place. Whether you’re packing for a bike park day, a backcountry ride, a moto mission, or a spring ski lap, the Defender is ready to go.

Defender 15 Hydration Backpack Specs

Hydration, Storage, and Protection in One Pack

The Defender 15 was designed for riders who want one pack that can handle real trail days. The included 2L bladder keeps hydration close, while the 15L storage capacity gives you room for tools, food, layers, gloves, and the small stuff that always seems to matter once you’re already out there.

The removable spine protector and back shell help separate the Defender from standard hydration packs. It’s not just a water backpack — it’s a protective, trail-ready pack built for riders who push into rougher terrain.

Built for More Than Mountain Biking

While the Defender 15 is a serious mountain bike hydration pack, it is also versatile enough for moto, snow sports, hiking, and year-round adventure days. The storage layout, attachment points, hydration system, and protective back panel make it a dependable pack when your day requires more than just a bottle and a phone.

Trail-Tested and Rider Approved

The Loam Wolf called the Defender 15 “one of the most thoughtfully designed packs” they’ve tested, highlighting its balance of function and comfort.
