Product Details

BLINDSTITCH – flat seams for reduced risk of chafing
The BLINDSTITCH construction is based on flat seams that reduce friction in areas that experience the most movement during running. This is particularly important on longer stretches, as minor irritations can quickly spoil comfort. The flat finish means that the fabric stands out less on the skin and works better with movement.

One zip pocket at the back – a safe place for small items.
The zippered pocket at the back allows for securely storing the essentials without the risk of them falling out while running. The rear placement helps keep the contents closer to the centre of gravity, which enhances comfort during movement. This solution is ideal for a key, card, or other small items that need to be well secured.

Slim fit cut – less looseness, more control in movement
Slim fit sits close to the body, which means the leggings do not get in the way at a higher pace and do not cause the fabric to flap. This cut promotes free movement of the legs while providing a sense of organised fit on the thighs and calves. It is also practical under shorts when you want to achieve a layered look.
