Cap unscrewed itself
Reviewed by Shopaholic from Hong Kong on Tuesday, May 14, 2013
I bought Hyperflow Cap, Push-Pull Cap and normal Cap, but this normal cap just can't close tight. I have three colors of them and surely it's not my problem. The main problem is the cap can easy be unscrewed itself while travelling. Never put it inside the backpack unless you have stored everything in dry sacks.
