What People Are Saying
Mitchel K.Fenix HMR65R-T V2.0 Review
Super stoked on the new V2.0 version of this headlamp. The new ratchet system is a great improvement. The update headband is fantastic. And the purple colour scheme is super cool. I’ve owned multiple Fenix lights over the past few years and I won’t consider any other brand for future purchase. Happy customer.

There are five reasons why I purchased this Klarus XT1C flashlight. It can be programmed for one button instant strobe. One,Defense from bears or people. Two, Offence, red light keeps you hidden at night. Three, USB-c battery usually an upgrade. Four, small pocket sized and five, Klarus is a good brand name.
