Simply pull lightly through the spout, and you can drink from your bottle just like normal. If the flow slows, give the bottle a shake with the DayCap attached to clean it and restore full flow. Built tough with premium materials, the cap features a sturdy loop for easy carrying and hanging. The spout is designed for smooth, effortless drinking, and the flip-up, leak-free cover stays out of your way while you sip. When you’re not on the trail, the DayCap serves as a perfect everyday cap. With the filter on, whether you’re day hiking or backpacking, the DayCap In-Bottle Filter makes staying hydrated worry-free and super simple.

  • reviews

    "This is a good day hiking filter, where you’ll just be filling it and drinking (only very light suction is needed to pull water through the filter. "

    "I bought this because I don’t always have access to the best water. That being said this filter is fantastic, most of the time all I can taste is cold there is no flavour or smell to the water."
