Luno In Latin, Luno means curve or shape into a crescent. Our Luno singlets are designed for the strength and the curves of an athlete. Our Luno singlet features a new racerback design for extra lat mobility, side panel stitching to help visually guide the squat depth level and curved panel design for a slimming look. The new Women's cut features a more tapered waist and additional quad room to fit all the strength and beauty.
