The antibacterial finishing prevents the growth of bacteria by 99% or more (lid, stopper, and stopper cover)*

We want to deliver bottles that are safer and more reliable.
With this in mind, we used an antibacterial finish.
On the lid, stopper, and stopper cover with the antibacterial finish, the growth of bacteria is prevented by 99% or more, compared with untreated ones; this means the bottle can be used hygienically at any time.

Clean and easy-to-use, sustainable stainless-steel straw that resists stains and odors

A stainless-steel straw that can be used hygienically is incorporated into the spout. You can drink the contents easily without tilting the bottle greatly. The stainless-steel straw has higher resistance to stains and odors than resin straws. It can be washed in water, which makes cleaning easy, and can be kept hygienic. The stainless-steel straw is highly durable so that it can be used for many years.

Structure that allows you to drink the contents easily even with a mask on

The design that considers ease of opening makes it simple to do so with one hand

The loop stopper designed to make the lid easy to open with one hand is used for the part to open and close the lid. The mechanism allows you to push the button to unlock the lid with one finger and then hold the loop with the finger to open the lid. You can rehydrate yourself easily while working at your desk or enjoying outdoor activities.

Magically light! The ideal dream weightless bottle to carry around

The weight was reduced by using Tiger’s proprietary spinning technique. The 0.5 L dream weightless bottle that weighs approximately 230 g is ideal for everyday use.

Reliably keeps drinks cold thanks to vacuum insulation

High cold-storage performance achieved with the stainless-steel, double-walled, vacuum structure!
Cold drinks will stay cold, so drinks can be kept at the best temperatures for drinking for at least approx. 6 hours.

Resin bottom that absorbs a sound that may be made when you put the bottle on a table or desk

The resin bottom is used to help prevent the bottle from being damaged or slipping on the surface of a table or desk. The bottle is also recommended for use in quiet places as the resin bottom reduces the noise made when the bottle is placed on a surface.


Removable and washable stopper with straw

The parts can be removed and washed in every corner for hygienic use.
