STRAW CAP 250/500mL (8 OZ / 16 OZ)

83 reviews

Our custom bkr Straw Cap is made for use with our bkr Soft Silicone Straws only (no rigid straws please, it’s a safety thing). It’s made with the same BPA-free, phthalate-free food-grade polypropylene as the caps you know and love and has a clear silicone valve to hold your straw.

To use it you’ll first screw the cap onto the bottle, then insert the straw through the clear silicone valve. This cap is splash resistant. It will keep your water in its place during light turbulence on a flight somewhere fabulous, but if tipped over in your bag some water may spill out. It’s dishwasher safe on the top rack like everything we make, and the valve is removable so you can wash all the parts thoroughly for zero yuck.

Perfect for on-the-go

I love the straw cap (and a cute BKR straw) when I’m driving or working out.

A must have for your bkr

The straw cap is an essential item to have with your bkr. They work well, are designed well, and make it easy for you to keep a straw in your bkr to sip all day long!

An absolute game changer!

One again bkr has filled a need I didn’t know I had! The straw cap is great and I find I’m drinking more water now that I’m using the straws. The straw cap holds the straws securely.
