Backcountry Gear gets it: camping and hiking gear should help get you out into nature while not weighing you down with what it takes to get there. Your outdoor adventure shouldn't be hindered by heavy kitchenware, overwrought backpacks, or complicated camping tents. Get equipped with the right gear, but not too much. It's about efficiency and versatility, minimum weight for maximum benefit. Backcountry Gear, where minimalism meets productivity.

Backcountry Gear knows lightweight backpacking is all about keeping things compact and sensible. Hiking gear should be sturdy, reliable, and lightweight. Camping tents should be constructed of lightweight, durable materials, and be easy to assemble. Kitchen kits should be featherlight and easy to clean. Trekking poles should keep you balanced. Accessories like medical kits should be comprehensive and intuitive. We understand, and we understand not every hiker is the same.

Our inventory has a backpack for every pursuit. We have ultralight daypacks, hydration packs, packs for kids, duffles, and child carriers. No one gets left out. We have dog packs, lumbar packs, dry bags, travel packs and luggage, courier bags, shoulder bags, and external frame backpacks. They’re all engineered by the best in their fields with features that make getting to what you need rapid and simple.

Backcountry Gear has reliable ultralight stoves and titanium cookware to make cooking a cinch and camping a treat. Canister stoves or liquid fuel stoves, we have one right for you. Boil water quickly with Jetboil's Sol and MSR's Reactor, or go ultralight with MSR's Micro Rocket and Primus' Express Stove. Keep weight down with ultralight titanium pots, pans, and utensils from Snow Peak and Evernew and keep going.


For multi-day hikes, Backcountry Gear has go-to water treatment options for every water source. Pump and be sure with MSR's Hyperflow Microfilter or Katadyn's Hiker Pro Microfilter. Or avoid chemicals and pumps altogether with gravity filtration systems from Platypus or UV sterilizers from Steripen.

We stock the best in sleeping bags, lightweight tents, and ultralight backpacks, too. When you plan for the outdoors, plan on, your first stop for outdoor adventure. Every step of the way.
