The piece
A long sleeve knit with thermochromic yarn knitted through it. Below roughly 15C the fabric reads orange. Warm it up and it shifts to yellow - gradually, across the range, not a hard jump at the threshold.
Because the pigment sits inside the yarn rather than printed on the surface, the colour change does not crack, peel or wash off the way coated or printed pieces do.
Fit and feel
Relaxed long sleeve cut with a ribbed cuff and hem. Size up if you prefer an oversized look - our size guide lists chest and length for every size.
Care
Wash cold, air dry, and avoid hot tumble drying. Heat is what drives the colour change, so keeping the wash cool extends the life of the effect.
