Tommy Heinrich, the first climber from Argentina to summit Everest, took several OP/TECH USA products on his trips in May of 1995 and May of 1998. He's determined to climb without oxygen - but not without his OP/TECH USA gear! We all wish him safe journeys.
Tommy was involved with the recent Polish HiMountain Nanga Parbat Winter Expedition 2006/2007 which was covered by National Geographic magazine.
