Like the rest of our Rambler series, this bottle features a No Sweat Design to keep your hands dry with double-wall vacuum insulation to lock in temperature. Its 18/8 stainless steel construction stands up to even the toughest of conditions, and you’ll find the leakproof, 3-finger grip, insulated TripleHaul Cap protects your truck cab or day pack from spills.The Rambler family is now sporting DuraCoat Color, the durable new look available for your Tumbler, Colster, or Bottle. YETI DuraCoat Color is available in four different shades: Seafoam, Tahoe Blue, Black, and Olive Green. It's designed to go on strong, and we think it's pretty good looking to boot, making it perfect for our stainless steel drinking vessels. It won't fade, peel, or crack through extended field use, and our DuraCoat Color provides additional grip to the Rambler's exterior. So whether you have your sights set on a Seafoam 20 oz. Tumbler or a Tahoe Blue Colster, our DuraCoat Color will hold up through the life of your warranty.

### ⭐⭐⭐⭐⭐ Review
*by ま***る on 21 December 2025*

イエティの温度保持機能はさすがですが、その分少し重いです。飲みやすい飲み口、手を入れて洗い易く、日常使いに他の水筒は使わなくなりました。注文してすぐに届きました。
