## Description

Rambler 18 oz. BottleThe perfect addition to your rough commutes, day hikes, or kayak sessions, this insulated water bottle has the power to keep your water cold (or coffee hot) until the last sip. 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: Shockingly bad! - Item was defective and I requested a return the same day…the seller would not collect, so eventually I paid for the item to go back, the seller then refused as the return window ‘closed’ so I have paid for item which didn’t work, paid to return it and have no refund. Essentially paying for an item I don’t even have. Would never deal with these guys again!
Review: Solid - Can’t fault their products - the best
