C&Berg 30 oz Tumbler Lids, 3.75" Replacement Lid with Slider, 2 pcs

Perfect fit on two different brands of stainless steel 30oz. tumblers. Cold 1 and North. The Cold 1 is slightly shorter but necks down to fit a standard cup holder later then the North. Honestly, these lids fit at least as well as the original ones. I haven't bothered to fill one up and turn it upside down, but I don't think they were designed for that. What they will do is prevent spillage when driving, biking, or hiking. Definitely worth the cost.

My 7 year old RTIC and Yeti tumblers, that I use every single day, have worn out lids. Meaning scratched, faded, worn on the sides, not just the rubber seal but the whole thing from taken them off and putting them back for 7 years. Based on reviews I doubted these would fit but for the price decided to try them anyway. As far as durability I cannot comment since I havent had them that long, considering the originals laster almost 7 years and probably a couple of thousand dishwasher dishwashings these would have a long way to go to match that. Lid replacement, perfect match. Size, obvious from my previous comments, perfect. Ease of use (Yea, I'm going by Amazons ideas), well, it's a lid, it pops on and pops off. When it is on it slides open and slides closed. So yea, lids are pretty easy to use all the way around and these are no different. All in all, yes these deserve five stars. As for durability, even if they last two years they are still worth it for the price, because one OEM replacement lid is twenty five bucks.

Good Morning World, I love my RTIC 30oz Tumbler, but the OG lids have an open mouth slot. I am a klutz. I can't wear white. Ok that last one has many reasons, but anyway, I tried the flip-top lids, but they have 3 problems. 1. The Flip-top lids are not anywhere near spill-proof. They are only spill-resistant. 2. The flip-tops are brittle and a simply short drop will break the clip on the flip-top. 3. The flip-tops never fold flat and bop your nose when you drink. So I found these lids from C&Berg. The lids have one key difference from all the others out there: The closure slides! Ah! No more pushing the flip-top against my nose. And the best part is that the closure gets "tighter" as you slide it closed. This simple, but smart, design feature ensures the lid is as close to 100% spill PROOF as you can get. Caveat on the prior statement: I noticed that after you close the lid and tilt the tumbler, there would sometimes (but rarely) be a very slow leak. To fix this, simply slide the closure back and forth a couple of times to get rid of any residual liquid surface adhesion off the silicone pad. No leaks. Ok. So a couple of things after a month of usage. First, there is really only one slight Achilles heel. The gaskets are a little soft and/or the ridges are too thin or pliant, or...something. After many usages, the lids come off easier and the gaskets seem like they could be just a tad thicker. I've already communicated this to their customer support. Again, they don't leak, the gaskets could just be "better". So instead, I replaced the C&Berg gaskets and replaced them with the OG RTIC gaskets and a the flip-top lids I had purchased previously. Now they are 100% perfect. My test for the gaskets was to pour the tumbler full of hot coffee and some creamer, close the lid tight and shake. A tight gasket will not spray liquid under pressure. The OG gaskets and the flip-top gaskets don't leak, but the C&Berg gaskets do. Again, it's a test that will not often be an issue in the real world. A stronger gasket would just make a great product perfect. Second, the sliding part is a piece of hollow plastic with some silicone pads. At first glance, it might appear hard to clean as the slide doesn't appear to come off. Liquid and condensation gets into that area and some residue, pushed around by the silicon pad, also gets underneath. While you can put it under running water and water can get into (and drain out from) the hollow area, I was worried about long-term usage and the possibility of mold or other growth in that area. BUT it is easy to clean. The easy? Use a towel (so your finger does slide) and press on the side of the sliding closure and pull slightly away from the lid and voilà! It comes off completely so it's easy to clean. Another way to get it off? Push firmly on the bottom of the lid against the silicone pad. See the latter procedure in this quick YouTube video: https://www.youtube.com/watch?v=4jWyx_OVuk8 Third, not a concern for me but it could be for others is that the silicone on the slider is easily stained by coffee. The stains have no effect on the cleanliness of the lid. If you still are concerned, soak the lids in 3% hydrogen peroxide mixture made by diluting 2 1/2 tablespoons of bleach in 2 cups of water. Either will bring the silicone pads back to their original white. I heartily recommend this lid as a replacement for any 20-30oz RTIC or Yeti or similar Tumbler (even the generic ones at BB&B largely use the same lids). The price is good and it took me many failed purchases to find this product. Don't make the same mistake I did. Buy THIS one. You won't be sorry!

Time for biannual replacement of lids on my 2016 workhorse of a stainless steel tumbler -The BEAST made by GREENS STEEL. The mug users in our home prefer the lids with the sliding cover feature rather than the flip type lid as we are too easily frustrated by the distraction of our nose and/or eyeglasses doing constant battle with the flip cover. Now, as fate would have it, whenever the need arises for lid replacement, I am always disheartened to find that the previous vendor/supplier is either no longer in business or no longer stocks the model I previously purchased. Grrrrr. Time to tediously scour the internet, hone in on what I hope/pray will fit my cup dimensions and personal preferences - then bravely bite the bullet by hitting the BUY button. Happily, this time my efforts were not for naught. While the mouth opening of these lids could be a bit larger on these lids, I can at least proclaim success in that they fit the 12 5/8" exterior circumference of my old faithful 2016 BEAST TUMBLER. Although my husband admits disdain for the smaller drink opening/limited flow of these lids, he has thus far found pleasant remedy by using a disposable straw. Being the utilitarian house manager that I am, my main focus is maintaining the overall function of these cups and keeping the bugger clean, which fortunately for me has seldom been an issue. Pretty simple. Just disassemble everything (hand clean any stained areas) and place each component onto the top shelf of dishwasher (cup, gasket, sliding cover, the lid itself - along with the big, comfy handle). Everything comes out clean, dry, and spotless! Now, I've read product reviews from many who complain of inability to ADEQUATELY CLEAN the space underneath the cover that slides over the mouth opening. Well, since 2016 I've used the same process which is to "pop" off the sliding cover, clean off any stains (or heaven forbid - mold) within the nooks/crannies and place in a secure spot in top level of dishwasher. Now, I won't lie... "popping off" that sliding cover can be a daunting task the first few times you make attempt. It is secured quite well and feels as though it will break - and in fact may produce some ominous cracking/noises of impending breakage during your first struggle to remove. Patience, persistence and and determination is the key, though. I use either my pinkie finger or the flat end of a BIC ballpoint pen to push into the soft center of the silicone pad with just enough force to pop the cover. (Fortunately, in 6 years I have broken nary a lid.) I discovered that the repeated process of removal makes each subsequent cleaning routine faster, easier and stress free. The ultimate reward? Spotless, sanitary cup lids! Even though I would prefer a larger opening to facilitate flow of drink, I think this four pack of lids are high quality and economical. I have had no problems with leakage thus far. If it ever should become an issue, I would first try replacing the old gasket with a new one rather than buying an entire new lid. REMINDER: These lids WILL NOT FIT my NEW 2023 BEAST 30oz TUMBLER (the lids are too SMALL).

Fits great works as it should

These lids are the best lids on the market!! Once you put them on and slide the slide to close the opening it makes the cup spill proof. My spouse dropped his full cup of coffee the other day and because he had the lid on with the slide closed it did not spil and the lid did not fly off. It like vacuum seals. It's great

If you use sodas in your Yeti, this is a bad lid. Since it seals so well, the build-up of carbonation will easily push the lid right off and "spill-proof" factor is undone. A self-defeating product.

Work great! Knocked over when full and don't leak! No cleaning instructions included. Tried to remove the slide with the seal and broke the slide.

Lid fits but rubber ring to thick so doesn’t fit. Have to use old ring to use.

Tapas perfectas para el Yeti. Recomendable totalmente.
