Product Details
The Gen II Big Data Armband was made for match day. Store your DOPE, ballistic data, match notes, tape or dry-erase marker board data, wind values, route, coordinates, codes and communication data, and any other information you need right on your forearm for easy access.
The Big Data Armband features a base pad and a fold-open flap for a total of 3 visible data windows. The windows are made from clear, matte PVC for a low-glare finish, and will fit true 3x5” DOPE cards that contain your custom data. Store a pen or marker on the low-profile elastic loops so you can take notes on the fly. Add a second pen or chemlight with the optional add-on*. The top flap closes securely with soft-touch hook and loop for quiet open and secure close.
The arm board's adjustable band will fit your arm and stay in place thanks to the double triglide system, and the elastic straps will stay comfortable throughout the day. Finally, this wrist coach is backed with a compression-molded foam layer with Lycra fabric, designed to improve airflow for additional all-day comfort.
