We have a hard time coming up with a more natural outdoor activity than gathering around a fire, and the Decahedron Fire Pit ($750) takes the classic fire pit and turns it into a functional art piece, making it a great place to come together. Naturally finished, and made from 4mm CNC engineered plate steel, each of the 10 pentagon pieces join to form a spherical shape. The removable and adjustable grill lets you cook while you relax by the fire, so now all you need for the perfect summer hangout spot is a cooler with a built-in stereo.
Whether you're a hardcore survivalist, amateur woodsman, or somewhere in between, you never want to go too long without access to hot water. The SunRocket Solar Kettle ($67) takes the trouble out of heating or boiling water, whether you're looking to purify, melt snow, or cook a meal. It's small, so it fits conveniently in a pack, but it still holds 17 ounces. It can heat water in just 30 minutes, using only the power of the sun. Once you've heated it up, the kettle acts as a thermos, keeping water warm for hours.
While you won't see Seal Team Six storming walled compounds with iPhones strapped to their rifles, it doesn't mean yours isn't welcome at the range. Turn your device into an optical system with the Inteliscope Tactical Rifle Adapter ($70), a combination Picatinny or Weaver rail mount and iOS app that brings ballistics and environmental information to your next shoot. It has a HUD with custom crosshairs, digital zoom, video recording, compass, GPS, and all the data you could want. The reinforced mounting system protects your device, allows portrait and landscape orientation, and lets you aim around corners. It won't make you shoot like special ops, but it couldn't hurt.
