Why you’ll love it

Sweat-proof

Discreet, highly absorbent underarm panels are engineered to trap sweat before it shows, keeping your outer shirt dry-looking and protecting against up to 2 litres of perspiration.

Odour repellent

The technological properties in the fabric repels odours. Our customers wear our products 3.8 days on average before washing*.

*Based on yearly customer survey, January 2026.

No shrinkage

The fit you love - every time. Engineered to maintain its original size and fit, even after repeated washing. No surprises. No shrinking.

Softer than cotton

Made with premium TENCEL™ Lyocell fibres, giving the fabric a smoother, softer feel than traditional cotton.

Made of Eucalyptus trees

Derived from eucalyptus trees, TENCEL™ Lyocell combines natural comfort with a luxuriously soft feel and excellent breathability.

Invisible under a shirt

Designed with a deep V-neck and seamless edges, so it stays hidden under an open collar without showing through.
