Lost the original cap on a hike and this replacement fits perfectly. The two included straws trimmed easily to size. Now my bottle is better than before because I prefer sipping through a straw. Fits snug, no leaks, great color match.
Replacement for a chewed-up cap. Snaps on securely and doesn't leak in my bag. Straws need trimming which took two tries. Happy overall.
Highly recommend converting your wide mouth to straw. Game changer for driving.
The flip mechanism was really stiff out of the box and I nearly thought it was defective. It's loosening up over time. Seals well, no complaints on leakproofing.
I was worried a replacement lid might not seal like the original. It does. Screwed it on my 32 oz Wide Mouth and it's airtight, tossed it in my work bag face-down as a test and nothing came out. The Capri Blue matches my older bottle that has faded a bit. Two straws included means I have a spare already cut.
Drinking more water now that I don't have to unscrew a cap every time. Fits my bottle perfectly and the gasket looks durable. Simple product that does exactly what it promises.
Bought this as a backup and ended up using it as my daily cap because I like the straw. Only note is that the straw trimming takes patience. Quality matches the original.
Listing says Wide Mouth but it would not thread onto my 2019 bottle properly. Might be a sizing change over the years. Returned it.
True story, puppy chewed my cap to pieces. This replacement arrived fast, fit like a glove, and came with two straws. Cheaper than a whole new bottle and the color is cute. All fixed.
Does what it should. Threads match, seals tight, easy to sip from while cycling. Took off one star because the cap can pop open if it jostles against other things in a bag, though it still doesn't leak when that happens.
Bought one to try, then ordered caps for all three of our bottles. Everyone prefers the straw now, even my teenagers. Great value at ten bucks.
