You’ve already got the water bottle, now you just need the clean water. The DayCap In-Bottle Filter seamlessly fits onto three popular wide-mouth water bottles—Nalgene®, Hydro Flask®, and Yeti® Yonder™—and transforms them into fast, safe and incredibly easy water filters.

Features:

• The removable filter utilizes the same hollow fiber technology as Platypus' award-winning backpacking filter systems to filter water safely and quickly
• By only lightly pulling water through the spout, the speed of the filter allows you to drink as you normally would from your bottle
• If the flow begins to slow down, simply shake your bottle with the DayCap and filter attached to clean it and restore the flow rate
• Made of premium materials, the cap is durable, and features a sturdy loop for secure hanging and carrying
• The spout is shaped to optimize flow and provide a natural drink experience
• It has a flip-up leak-free cover that stays out of the way when you’re drinking
•  In cap-only mode, the DayCap works as a perfect everyday cap for your bottle when you’re not on the trail
• With the filter on, whether it’s a day hike or a backpacking trip, the DayCap In-Bottle Filter makes worry-free hydration as easy as scooping and drinking
