MATERIALS & CARE GUIDE

Care Guide: Seamless underwear uses ultra‑fine fibres and bonded construction for a smooth, second‑skin finish, so proper care is critical. Wash cool (≤30°C) on delicate with gentle, pH‑neutral detergent, ideally in a mesh wash bag. Always air dry (tumble drying is an absolute no‑no) and keep away from direct heat/sunlight. Never use fabric softeners, bleach, or dryer sheets, and don’t iron or dry clean. Full care instructions can be found here.

WITH Fitknicks

WHat they're great for

FitKnicks Seamless undies are made for women who train hard and want their underwear to work just as hard. They also don't want their knickers to feel like they could double as dental floss.

Designed for the demands of the gym, these undies disappear under tights, shorts, or compression wear: no VPL, no awkward lines, and definitely no wedgies. The antimicrobial, moisture-wicking lining keeps you feeling fresh and dry through even the sweatiest sessions, while the seamless construction means you can move, stretch, and lift without any rolling, bunching, or discomfort. And with the nude shade, you get total confidence even under lighter-coloured leggings.
