Summits On The Air (SOTA) activity is becoming increasingly popular as well as Parks On The Air (POTA). People climb mountains and hills to "activate" certain summits. Especially for SOTA, weight can be an important factor if the gear has to be lugged up steep hills or mountains.
LNR Precision make some gear aimed at these users. They are compact and lightweight.
