We designed Whiteout 30 for alpinists and ski mountaineers who are extremely hard on gear. Dyneema is amazingly tough fabric and during the testing phase proved itself up to the task. In fact, EXPED ambassador, Graham Zimmerman, used his Whiteout to haul rocks at basecamp during his 2019 first ascent of the giant, unforgiving and unclimbed Link Sar in Pakistan. Later in the climb he hauled his gear to the summit in the same pack - see below.
