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. The removable filter utilizes the same hollow fiber technology as our 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.
Transforms your favorite wide-mouth bottle into a fast and easy water filter.
- Easy-to-Use: The drink experience is practically the same as without the filter thanks to the high-speed filter and the flow-optimized spout.
- Proven Filtration: Hollow fiber filtration media is the same technology as our most popular and field-proven filters, with a flow rate up to 1 liter per minute.
- Safe & Effective: Each filter is individually tested to ensure it meets all EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa.*
- Easy Cleaning: Simply shake to clean with it attached to your bottle to break up particulates and restore flow rates.
- Optimized Design: Filter detaches with an easy half turn for cap-only mode while the semi-flexible carry loop is a sturdy attachment point.
- Premium Materials: TPE mold construction is durable, grips well and complements the quality of your bottle.
Comes with DayCap cap and removeable filter cartridge.

Light weight
Light weight and thin. It is nice for 40-60 degree weather, but anything cooler you would want to consider a thicker cashmere.
Fit is oversized.
I didn’t like the color brown I chose—it’s more red tone—I would go with a more natural tone next purchase. Would purchase again and for a gift.

Perfect size
Color: Knot Gold, Color: Knot Gold
Beautiful high quality earrings! Not as heavy as I thought they would be given the size/design. Super comfortable and fashion forward. The color of the gold is closer to 21k rather than 18k (if you care about the yellowness). Either way, they're gorgeous! In the picture, the top necklace is 18k, the bottom is 21k for comparison.

Great
Color: Knot Gold
Love! Comfy, cute, perfect weight and size. Great quality. I noticed a lot of reviews mention the backs and while I think they’re comfortable, they don’t feel super secure to me and I might use different ones
