The XT11S brings together 2 tried and true UIs for use in a system most would discount it for. It has a side switch under the head and two tailcap switches which can be used with just your thumb. The XT11S is also long enough to have the side switch be just outside a weapon mount, making for instant access to the different light settings available while hunting.

Machined from aircraft-grade aluminum alloy and hard-anodized, the rechargeable XT11S uses 1 included buttontop 2600mAh 18650 for power and also has a battery slot able to take the recoil of a gunshot. The micro-USB port is behind the side switch, which acts as a power indicator during use.
