The Tayst 20 oz travel mug tumbler is a double-walled vacuum-insulated tumbler in 18/8 food-grade stainless steel. The vacuum gap between the walls slows heat transfer, so hot drinks stay hot and cold drinks stay cold, and the powder-coated exterior stays sweat-free and cool to the touch with hot liquids. It is a straightforward everyday tumbler for commutes, desk use and short trips. Against rivals it lacks a handle, lid-style straw options and a tapered cup-holder base that many competing 20 oz tumblers offer, and it is hand wash only. Owners rate it highly, at 4.8 out of 5 from 100 ratings.

Owners rate the tumbler 4.8 out of 5 across 100 ratings, praising its insulation and clean exterior. Complaints are few and center on hand washing and capacity.
The Tayst 20 oz. travel mug tumbler has double-walled vacuum insulation. The space between the two stainless steel walls is empty, so there is no medium for heat to transfer through. The temperature of your drink is not affected by the temperature outside the tumbler, so hot drinks stay hot longer and cold drinks stay cold.
The interior is 18/8 food-grade stainless steel. It is BPA-free, FDA approved and highly resistant to rust. It is easy to wash by hand.
The exterior stays free of sweat and heat. Hot liquids do not affect the outside of the tumbler, and no condensation forms. A durable powder-coated finish has a fingerprint-free texture and is easy to clean.
