Are you old enough to remember when reusable stainless bottles came out? That is when I purchased my first Klean Kanteen bottle. It lasted for 20 years and finally kicked the bucket when the lid fell apart on me. 20 years!!! Wanting to try a new brand and researching this one, I invested the money. The first few days I was in love! I had never tried a sports cap before and it was super convenient and practical for my active lifestyle as a new mom, running a cat rescue, and working part-time at a delivery company. The construction of the whole system is aesthetically pleasing and it feels good in the hand and fits in cup holders. But I put it on a carabiner- smooth, round and strong enough to hold the bottle attached to my belt bag, and within 30 mins the cap loop snapped and my brand new $41 bottle came crashing to the ground. It's dented, the loop is forever broken without purchasing another, and I'm frustrated. I went back on their website and purchased a metal cap so when that comes I'll update on that review. I REALLY like the bottle, I just wish the cap was sturdier. Seems like a pretty big blind spot considering they advertise pictures of their bottle attached to a carabiner backpacking. Really hoping the metal cap helps even if I lose that loop feature!
