SDP Condensation Control
SDP was originally developed for use in Military applications, and has gone on to be used by Tactical Forces, Mountain Rescue and Emergency Services requiring performance clothing that works as hard as they do.
It has become a popular choice with the outdoor community and has been used to conquer the world’s toughest mountain summits and survive the harshest Arctic conditions.
In recognition of SDP’s success, Keela was awarded the Queen’s Award for Enterprise: Innovation, one of the UK’s most prestigious awards, which recognises outstanding achievement in the categories of international trade, innovation and sustainable development. Keela are grateful for the recognition of their innovations and continue to further develop System Dual Protection to ensure our customers know they can face the elements with confidence and in comfort.
