S'well Stainless Steel Traveler 12oz - Keeps Drinks Cold 20h Hot 9h

In this review of the S'well Stainless Steel Traveler 12oz, the bottom line is simple: this compact bottle is for anyone who wants reliable temperature control in a stylish, easy-to-carry package. The single biggest reason to buy is its triple-layered insulation, which delivers long-lasting cold for up to 20 hours and hot for up to 9 hours while maintaining a condensation-free exterior. Its small footprint and wide mouth make it particularly useful for commuters, purse carry, or short trips where durability and temperature retention matter.

Key Features

• Therma-Swell Technology: Triple-layered, vacuum-insulated construction keeps beverages cold for 20 hours and hot for 9 hours for dependable temperature control during the day.
• Wide Mouth: Ice cubes slide in easily and the thick rim makes drinking comfortable without spills or awkward sips.
• Condensation-Free Exterior: The bottle does not sweat, so it stays dry in your hands, bag, or backpack and protects other items from moisture.
• 18/8 Food-Grade Stainless Steel: Durable, BPA/BPS-free construction offers a reusable, safe alternative to single-use containers and complies with California Prop 65 regulations.
• Ergonomic Shape: Slim profile is designed to fit securely in backpacks, side pockets, and most cup holders for easy travel value.

Who It's For

The Traveler 12oz suits commuters, students, and anyone who prefers a compact bottle that fits into purses or small backpack pockets and still preserves beverage temperature. Its leak-proof feel and non-sweating finish make it a solid pick for daily use, short hikes, and car rides.

Those who need very large volumes, sport-specific spouts, or very narrow-necked thermoses for specialty flasks should look elsewhere; this model is optimized for portability and style rather than maximum capacity or specialized lids.
