YETI Rambler 36 oz. Water Bottle with Chug Cap

This is my first yeti water bottle and I am thoroughly impressed with the insulation. I filled the bottle with water and ice around 5-6pm and around noon the next day there is still ice in it. I will note, I wear a stainless steel ring which I can see is already leaving some small scratches on the exterior. I don't particularly mind this, but if you also wear jewelry you may want to be aware of this.

I have been using this water bottle both personally and professionally in wilderness search and rescue. I love the colour so much and the texture. I have dropped this thing so many times and the paint is still holding up pretty nicely. The only thing I don’t like is the threads to the chug cap, when they are wet it’s hard to unscrew due to hydrostatic friction.

Love this bottle and the free engraving! Keeps water cold and I love the 36 ounce size.

It’s been a while ago I bought around 20 Rambler Chug Cap bottles for my family overseas because I’ve always trusted YETI for its reputation of making high-quality cooling products. And I think it’s a perfect gift for them However, I’m really disappointed with these water bottles. They do not keep water cold as well as I expected — even with ice inside, the cold won’t last all day not even over 4,5 hours. I had a lot of confidence in the YETI brand because your products are known for excellent insulation and ice retention. But the insulation performance of these bottles has been very disappointing. What’s more frustrating is that this feedback has been consistent from every family member who received one. It’s not just a few defective bottles — every single one fails to keep drinks cold properly. Perhaps I misunderstood the intended performance of this product, but based on YETI’s reputation, I genuinely expected much better insulation and ice retention.
