I won’t lie. I’m a total flatlander. I live at sea level, and I completely struggle at altitude. Shortness of breath, splitting headaches, all that jazz, all of it happens to me once I get close to 8000 feet. Prior to Outdoor Retailer, a few friends and I headed out in the Uintas for some pre-show backpacking and gear testing fun. Our itinerary involved scuttling around 10,000 feet every day, so Oxygen Plus was kind enough to send along some Skinni Natural bottles.
