Additional cap for the Klean Kanteen Bottle.
The Sport Cap 3.0 effortlessly delivers a high flow rate that makes it easy to drink from your bottle without removing the cap. The cap has been completely re-designed with a soft silicone spout and better valve. So it is much more leak-resistant than the old Sport Cap. Anyway, please don't put it upside-down into your backpacks - it's not 100 % leak-proof!
Furthermore, drinking with this cap has become much quieter now - no funny loud voices anymore.
Of course, it is free from BPA und other toxic chemicals.
