Stay cool and dry – Thanks to lightweight, breathable Performance Tech fabric
Performance Tech uses a lightweight knit made from recycled polyester with a soft-touch finish and moisture-wicking construction that encourages air flow and sweat dispersion.
Cooler microclimate and reduced cling make long training sessions and travel more comfortable, preventing that sticky feeling after exertion.
Reduced odour, sustainable choice – With recycled polyester treated with metal-free odour control technology
Fabric is made from sustainable, recycled polyester and finished with a non-biocidal, metal-free odour control treatment designed to limit odour retention without metal-based additives.
Underwear stays fresher between washes while using recycled materials, making it a sensible option for frequent wearers mindful of sustainability.
Chafe-free movement – Thanks to 4-way stretch, mesh zones and seam-free panels
Four-way stretch construction allows fabric to move in every direction; mesh zones in the pouch and gusset improve ventilation; absence of side and back seams and an articulated fly reduce friction.
Freedom of movement without rubbing or irritation, suitable for running, gym sessions and long shifts on your feet.
