Ultra-versatile system with gravity filter for camp and a small filter for the trail

The most versatile water filter MSR has ever designed, the Trail Base 4L microfilter kit features the same smart engineering and modular design of the 2L version with twice the water capacity for just an extra 2 oz in weight. The kit lets you use the gravity system at basecamp, the pocket-sized, take-alone trail filter for on-the-fly hydration, and the fast-and-light reservoir for hiking or biking, or whenever you want to carry more clean water with you. The kit directly connects to standard hydration system reservoirs for hassle-free filling. And with the shake-to-clean filter, it’s super easy to clean—no backflushing required.
