Slender ultralight multitool sneaks in a stealthy 260-lumen flashlight

Designed to give you more of what you'll use and less of the tagalong bulk you won't, the new Tacray MT1 multitool leaves behind the beefy, flip-out-stuffed body in favor of a thin open chassis carrying a pair of implements. And it adds a much-desired feature that most multitool manufacturers leave behind: an integrated flashlight that works on its own or lights the way for the other tools. Forget mere EDC; the MT1 is also an ENC (every night carry) essential.

Impossibly tough inflatable tent stands even stronger in 112-mph wind

Believe it or not, the 112-mph (180-km/h) wind capability of the all-new Heimplanet Mavericks Blue Ice inflatable exo-frame tent isn't what separates it from all tents that came before it. The Mavericks tent has been handling that kind of wind for over a decade. But the ultra-rugged expedition-grade inflatable has gotten some burlier fabric, improved drainage, better ventilation and other upgrades to become Heimplanet's self-declared strongest tent ever. And even with that tougher-than-ever design, the revamped big tent also comes ready to set up in half the time of the original.
