Developed for and used exclusively by Yosemite Mountain Guides, the Ultralight Pro kit is now available for retail sale. Ideal for any outfitter, guide, trip leader, or mountaineer who needs to travel light, fast, and watertight in the backcountry. Professional-grade components include a Laerdal CPR Mask with O2 valve, SAM Splint, and deep stock of bandages, dressings, and medications. A pull-out Ultralight / Watertight .9 kit lets you keep weight to an absolute minimum on summit trips.
