Divvy Cube™ Stuff Sack. Rectangular stuff sack stows efficiently in your pack and lets you split the load with a partner.

Gatekeeper™ Door Tiebacks. Integrated clips let you tie back the tent doors with one hand.

About the brand

NEMO Equipment was born on a turbulent night in 2002 on the side of Mount Washington, where founder Cam Brensinger spent five sleepless hours in a poorly designed bivy and realized how much better outdoor gear could be with thoughtful design. He founded NEMO that spring in Nashua, New Hampshire — naming it after Jules Verne's Captain Nemo, and, fittingly, 'New England Mountain Outfitters.' At Mountain Sports, we love NEMO for that problem-solving, design-first spirit: award-winning tents, sleeping bags, pads, and camp furniture engineered for real comfort and built to last.

Do I need a footprint?

A footprint isn't required, but adding this layer of durable, waterproof fabric reduces wear and tear on your tent floor caused by rough or rocky ground — extending the life of your tent.

What warranty does NEMO gear carry?

NEMO covers manufacturing defects under its warranty program, and many categories carry lifetime coverage. Bring it by the shop or call us — we'll help you sort out any claim with NEMO directly.

What is NEMO's Endless Promise®?

Endless Promise® is NEMO's circular design program: products built to be repaired, resold, and fully recycled at the end of their life instead of landfilled. Mono-material construction means the whole product can go back into the recycling stream.
