The HydraPak 42mm Filter Cap turns compatible HydraPak bottles and reservoirs into a lightweight water filter. Drink straight through the cap or squeeze clean water into another container.
If you already own HydraPak soft bottles, this is the simplest way to add filtration without carrying another piece of gear.
Trail runners, hikers and backpackers using HydraPak bottles. Refill at a creek on a hike up toward the Sawatch 14ers.
