I bought this cap for my 17oz Original bottle and it fits perfectly. The straw flips up easily and the seal is tight – no leaks in my bag. It's also great that it's dishwasher safe. Highly recommend!
The cap is well-made and leakproof, but the straw is a bit short for taller bottles. It works fine for my 17oz, but I wish it was adjustable. Still a good purchase.
Great cap! Easy to sip and no spills. The sale price was a steal.
This cap is fine for cold water, but if you want to use it for hot beverages, the straw isn't ideal – it can burn your mouth. Also, the plastic feels a bit cheap. But it's okay for the price.
I like that I can sip without removing the cap. It's truly leakproof – I've thrown it in my work bag. The flip mechanism is smooth. Only minor issue: it can be a little hard to clean the straw, but the dishwasher helps.
I've gone through several caps for my S'well and this is the best. It seals perfectly, has a comfortable straw angle, and looks sleek. The 50% off was a bonus. I'm buying another one as a gift.
I followed the sizing guide but it doesn't fit my 17oz bottle properly. It wobbles and leaks. I'm disappointed.
