How it works
A triple layered armpit padding helps the undershirt absorb, and evaporate sweat as vapour. No visible stains, no compromise on comfortability.
Invisible under the shirt
Designed to act as an invisible layer between you and your shirt. V-neck allows for multiple buttons opened! Pair Khaki with lighter shirts, and Black with darker shirts for the best hidden result.
Sweat proof
Thanks to extra padding in the armpits sweat stains are a thing of the past.
Fun fact: can withstand up to 2L of liquid!
Odour repellent
The technological properties in the fabric repels up to 99.9% of odour-causing bacteria, while blocking sweat. Our customers wear our products 3.6 days on average before washing.
