MSR (Cascade Designs) Trail Shot Pocket-Sized Water Filter

Clean water all day without the weight. That's the advantage the TrailShot Microfilter provides. Designed to hide in stash pockets and deploy quickly this tiny water filter lets you drink directly from sources along the trail for instant hydration and fill your vessels with clean water. Easy one-handed operation filters one liter in a mere 60 seconds so you can get back on the trail quickly and moving again.

Features:

• Meets U.S. EPA drinking water standards* and NSF protocol P231 for removal of bacteria (99.9999%), protozoa (99.9%), and particulates
• Like small water bottles, energy chews, mini bike pumps, and tubes, this 142 g (5 oz.) filter disappears in stash pockets
• Drink directly from the source without lying in the dirt and refill your bottles or hydration reservoir with clean water
• Zero set-up and simple one-handed operation fills 1-liter bottles in 60 seconds
• A few shakes helps restore flow rates in the field; no tools required
