Once known as Relay, these leggings were renamed LIGHTSPEED because of their ultra-lightweight finish and aerodynamic seams. They’re still crafted from our original and bestselling Better Than Naked fabric though, to create a buttery-soft yet lightly body-sculpting silhouette that’s sweat-proof - perfect for warm-weather workouts.

Fitted with hidden technology at the waist to support and contour, plus a set of side pockets on each hip to stow your valuables, they’re now available in two different leg lengths and four colourways too - should you feel like adding a little variation to your kit bag.
