The mountains are crying to be climbed, releasing occasional torrents of crystal clear tears from the clouds above. That wet wailing might stop other adventurers, but we're answering the call and doing it with the Ortovox Trad 30L strapped to our backs. Its unprecedented waterproof rating and simply ergonomic design lend us plenty of room and complete peace of mind that our gear is safe from the high altitude elements. Because the last thing we need on long alpine tours is our precious backup layers and extra food getting soaked.
