Vacuum Insulation

Essentially a flask within a flask, a gap exists between the two stainless steel walls enclosing the tumblers’ contents. The gap, which has been partially evacuated of air, serves as a partial vacuum that reduces both heat conduction and convection, thereby leaving the contents of the flask unaffected by external temperatures for longer periods of time.

18/8 Stainless Steel

Evilkind® flasks are constructed from premium quality, 18/8 food-grade stainless steel resulting in a product that is 100% toxin and BPA-free. The 18/8 interior core is also highly resistant to the absorption of odor, taste, and bacteria.

Cold up to 24 hours • Hot up to 12 hours

Evilkind’s double wall vacuum insulated bottles will generally keep your cold liquids chilled for up to 24 hours and hot beverages hot for up to 12 hours. These estimates may vary based on usage and how often the sip top is opened exposing the inner contents to the outer environment. 

100% Bisphenol A Free Liquid Contents

This point cannot be emphasized enough and remains the sole reason Evilkind® has ventured to provide you with this private label product. BPA-contaminated liquids and foods exposed via containers derived from polycarbonate plastics have been linked to a score of serious ill health effects including, but not limited to cancer, diabetes, obesity, high blood pressure, hormonal imbalances, and neurological disorders. 

Powder Coating

Our flasks are finished with a stylish powder coat, meaning they have been put through an electrostatic process where plastic/epoxy powder is deposited in a very thin layer all over the surface and then baked on. This gives the overall finish a distinct texture and look and also allows for a paint job void of drips or runs.

Sweat Free

The double wall vacuum insulated construction also provides an outer surface that will remain condensation free. 

Sip Top Lid

Unlike other brands in this size and class of flasks, Evilkind’s 40 oz tumblers come equipped with a BPA-free, polyurethane plastic.
