The Steep Flask — Double-Wall Glass Tea Infuser Bottle for Travel

Loose-leaf tea that travels — and stops steeping when you say so. The Steep Flask keeps your leaves in their own stainless chamber at the top: tip to brew, set it upright to stop. Your tea at your strength, whether you drink it in five minutes or fifty.

No more bitter bottom-of-the-bottle. Unlike a basic infuser tumbler, the separation chamber means leaves aren't stewing in your tea for the whole commute. Brew it exactly as strong as you like, then stop.

Double-wall borosilicate glass. Hot tea inside, comfortable hands outside — and the slim profile fits a car cup holder and a backpack pocket.

Your tea touches glass and steel. The brewing path is borosilicate glass and a 304 stainless infuser — no plastic steeping chamber like the usual travel tumblers.

Two sizes, four finishes. 350ml (12 oz) for a single serious cup; 500ml (17 oz) for the long haul. Champagne Gold, Steel, Bright Black, and Queen Gold lids.

Rinse the chamber, tap out the leaves, refill at any kettle or hot-water tap. Pairs with The Steep Basket at home for the full plastic-free setup.
