Never leave home without it!
Great, lightweight filter. Gives you confidence any water can become clean and filtered. Water tastes great and easy to use. Love the included adapter to connect to your Camelbak. Just connect and pump filtered water right into your drinking reservoir. Recently went on a trip with a friend who had an MSR water filter. Being able to compare both side by side the Katadyn wins hands down.
#1 - Lighter
#2 - The MSR has a bulky handle that looks to easy to snap off
#3 - Smaller footprint than the MSR
#4 - Pumps out water at a higher rate.
