Why use the Klarus xt11s flashlight?

Durable construction

The first thing to look for in a quality tactical flashlight is whether it can withstand the hard conditions of the wild or not. If the light is poorly made, it will not last for long. But if it’s a sturdy one, it will be able to withstand the hard conditions of the wild. Klarus emphasizes quality and that’s why a good number of flashlights made by this brand are rated as tactical. The xt11s is a tactical light built for outdoor use. Its durable construction means that it can survive the impact from one meter as well as crushing.
