Review on 3-Pack Green Klean Kanteen Sport Cap 3.0 Replacement Caps by Michael Jennings

Revainrating 2 out of 5

The caps really suck as intended. They lick too.

High expectations and a decent price led to disappointment and damp after realizing they are actually NOT airtight no matter how tightly closed. The slow drip comes from a one-way exhaust valve, which is nothing more than a silicon flap covering several small inlets. Buyers beware - they cannot be boxed and must remain upright, defeating the purpose and utility of this particular make and model cover.

Pros
  • Absolutely amazing!
Cons
  • Some little things
