S'well Sports Cap, Fits 9oz and 17oz Original Bottle, 18/8 Stainless Steel Cap, BPA Free

Lots of previous reviews say this lid leaks. It does NOT leak if closed properly. The lid needs to be tilted ALL THE WAY to the back to drink out of it well. It needs to be tilted the opposite way ALL THE WAY to the front to be closed properly. If the tab is horizontal & even and you can see a sliver of blue it is not closed properly and it will leak. It has to be tilted. Please see the attached pictures. I ordered a 3rd party silicone strap for a carry handle since S'well is out of stock. It's easy to carry since it's flexible & no noise like from other carabiner handles I looked at. Thick, sturdy & inexpensive.

I was hesitant to purchase this lid because of the reviews where people state it leaks. I'd like to clarify a few things because I don't like it when items get a bad review due to user error. There are two cap sizes, one for the 9 & 17 oz bottle and one for the 25 oz bottle. Order the correct size. This is not marketed towards the Swell Sip bottles shaped like a triangle and I have not tried it on any of them. You can open the top of the cap by pushing down with your finger however; in order to get it to seal properly when you close it, you must push the flip cap down so that NO blue is showing - zero blue gasket showing. Otherwise, it will leak. This fits both my 9 and 17oz Swell bottles perfectly. It does take a bit to get used to drinking out of it as sometimes your nose can hit the opposite end of the lid. I definitely recommend.

We’ve been using other bottles instead of our Swell bottles when traveling because it’s inconvenient to unscrew a top when driving and other activities. There aren’t acceptable straw top options for these bottles. (Maybe 1 on amazon that doesn’t work well at all). The sports cap solves the problem. We have 2 of them now and although we haven’t had them for too long, there are no leaks at all so far. You have to be sure to close properly. The open position is a push down toward the low (back) end of the cap and it shows a blue stripe that indicates it’s open. The closed position is not flat which is what you’ll tend to do but more of a push down at the high (front) end of the cap. See pics and video. 2 limitations of the cap so far. I rec’d an answer for directly from Swell— is that you cannot use the cap with hot drinks. Also I don’t think the cap is insulated as we have found that the *drinks do not stay cold for long with the sports cap*. You trade the convenience of the cap for the temp of the beverage. The original screw cap keeps the drinks cold and the sports cap does not. The sports cap right now is only available for the 17 oz and 9 oz. It doesn’t fit any of the S’ip 15 oz bottles. Also no one makes a silicone boot small enough to fit the 17 oz bottle (only sleeves available). The Swell bottles are high quality bottles that keep drinks hot and cold for long periods but options for tops and protective silicone boots are limited.

I love my Swell Water Bottle but the lid is designed to be removed every time you want a drink. This top turns the bottle into a flip top for quick use. I love the convenience and the top fits perfectly. There's no leakage! Five Stars!

Had it for a while, I actually think this was a replacement for an old one. It works well. I wish these would come as standard tops instead of just the screw on!

S'well has changed their sport cap and they are totally defective. I purchased a sport cap in Nov. 2023 with a new water bottle. See the cap on the left in the pic. It still works fine. I purchased another one Oct. 2024 along with a new water bottle. After a couple weeks, it only opened part way, allowing almost no water to flow. I returned for a replacement, but the new one looks exactly the same. It took a bit longer, but also failed for the same reason. See the cap on the right in the pic. It's either a new design or a new mfr. The blue area looks totally different and the black part above the blue is way bigger. I emailed S'well with the problem re the defective sport caps that Amazon has in stock. I sent them the picture showing the difference and my proof of purchase. They told me to return to Amazon again because they had none in stock. I totally think a new one from Amazon would be the same if I return & replace again. Don't waste your money. If you want a sport cap, pick a different brand. Too bad as I really like the bottle, but their customer service is horrible. I replied they should offer to replace it when they get new ones in stock. If I get any satisfactory follow up from them, I will edit this review. Zero stars for now.

My original cap broke and I saw this one so I was like why not. Had it for about a year and honestly should've returned it when I had the chance. I find that the sports cap really limits the amount of water that can flow out. Most of the time I end up unscrewing the cap entirely. I will say though that flipping the cap open is much easier than unscrewing the whole cap. But I do find difficulty pushing the correct side sometimes. And at which point I completely touched everywhere near the opening where I would drink from - so much for being sanitary. Regarding leakage, I'm always concerned that I left the cap open. Even if the gaskets all work fine, if I left the cap open or if I didn't close it properly, it would be an issue. So I find myself paranoid and constantly checking before and after I put the bottle in my bag. It also feels not safe to just toss the bottle in the bag without ensuring that it's orientation is mostly vertical. So recently I dropped my bottle and it must've landed cap first. The plastic that the cap hinges on broke so the seal is not great anymore. Time to go back to the regular cap

I got a swell-shaped bottle from work and loved it, except I physically cannot bring myself to drinking out of screw-cap bottles. I was hesitant to get this cap initially because of the price and because I am typically a straw-drinker, but I got it to test and I’m never going back. Well – that’s a lie... I still love the ease of a straw, but this makes my water bottle the most appealing drink I’ve ever tasted somehow. I find myself filling up my bottle so many times in a day at work now. The only slight downside is that it leaks sometimes. This is because I’m lazy and don’t always push the cap all the way down. But, if you did, it would be completely leak-proof! All in all, this is a great cap! All of my coworkers happen to have the same bottle as me, but this makes it super easy to differentiate which is mine. I also now spend a lot of time running to the refill stations because the cap makes it easy to drink a tonnnn of water!

Excelente producto mantienen como es debido la temperatura, y los aditamentos son lo mejor

Easy to use, specially on the move

Love it when upright but sadly as others have said it leaks if it slides over in a bag. Great for my bedside drink but not for travelling

Very happy, just what I wanted. And came sooner than expected!
