## Description

## Key features

The 40 oz insulated water bottle from Coolflask keeps drinks tasting fresh while you move through a busy day.

It keeps cold drinks long, and it handles hot beverages when you need them.

## Tech specs

- Name: Water Bottle 40 oz Insulated with Straw
- Material: 18/8 (304) stainless steel
- Capacity: 40 oz
- Color: Samurai Cyan
- Type: Triple insulation, double wall vacuum

## Benefits

Triple Insulation Technology locks in temperature according to the manufacturer, so you get up to 48 hours of cold and up to 24 hours of hot. The anti-sweat coating keeps the exterior dry and improves grip, so it won’t leave rings on surfaces or feel slippery when you’re active. Three lid choices give real versatility, with a screw-on lid and flip-up handle for easy ice refills, a spout lid for hotter pours, and a straw lid for quick sips while on the move.

## Usage tips

It’s a great fit if you want fewer refills during long outings, since the 40 oz capacity extends time between stops. Hand wash only and avoid abrasives to preserve the finish, and do not place in a freezer or microwave. Be cautious with hot liquids to avoid scalding.
