"I first learned about SteriPEN when leading an expedition of Brown University researchers up Mt. Everest in 2002. I was really impressed with how fast and light the SteriPEN is. Since then I have used SteriPEN on Mt. Aconcagua in Argentina and recently again on Everest. Climbing at high altitudes can be dangerous enough without taking risks on bad water. Using SteriPEN is so easy - it is a great addition to my climbing gear. Thanks!!"
