Rated 5 out of 5 by from Excellent Product! I bought this because my husband likes smoothies for lunch. I make him a smoothie before he goes to work and pack it in his mini ice chest/lunchbox. The smoothies is still icy and perfect at lunch time! I will be buying more for myself and my kids.

Rated 4 out of 5 by from Works Great This is a great bottle! Ive always wanted a YETI that I can toss in my bag and this satisfied that! Keeps beverages cold. My only downside is that it is a little too small for me. I have to constanly refill the yeti because with ice, i cant get a whole water bottle into it. Other than that, works great!

Rated 5 out of 5 by from Greatest Bottle of All Time Brang this with me to Florida and it was the best think I brought I would fill it with ice in the morning and during the day the outside of the bottle would be hot and the inside still was still holding ice. The ice lasted over 26 hours for me one day. So glad I purchased this.

Rated 5 out of 5 by from Still hot in -35 sitting on the snow 4 hours later We filled the Rambler with hot coffee and headed out on the Chena River to watch the 2017 Iditarod mushers go by. It was -35F and the Rambler hung out on the styrofoam snow for over 3 hours while we took pictures of the sleddogs and mushers go by. Though the metal on the outside of the Rambler was burning COLD to the touch (as my dear friend found out), the hot coffee inside was still too hot to chug. Even when the Rambler sat in the truck for over 8 hours at 15F, the hot chocolate was still what I would consider hot at the end of the day. I can't possibly express how impressed I was with the Yeti Rambler.

Rated 1 out of 5 by from Great Body, Faulty Lid I bought the 18 oz rambler a few months ago and used it for a while with no issues. Then the lid basically popped it's top, exposing the Styrofoam interior. Generally I love Yeti products and own at least 5 of them (cooler, big rambler, tumblers, etc.) and normally i wouldn't complain, but it's also really hard to find a replacement lid (either on Amazon or Yeti website) for the rambler. I want to just keep on using all my Yeti gear and buy another lid without having to replace the whole setup. Hopefully i just got a lemon and this isn't a re-occurring problem for others.

Rated 5 out of 5 by from Stolen! I had my new Rambler for less than a day when it was "stolen" by my 16 year old daughter. The 18 oz Rambler is now covered in stickers and makes many trips to the Lacrosse Field. She loves how easy it is to get ice in and that it stays cold for the entire practice. I had also picked up a 32 oz Rambler and it was "stolen" by my son. The 32 now lives between Boy Scout Camps. Both products have worked out awesome for our family.
