Protectors Long Sleeve

The long sleeve T-shirt is a versatile essential, an integral part of any wardrobe and an ideal choice for transitional seasons.
This straight-cut model features long sleeves with cuffs and a classic crew neckline. It is made from premium mid-weight knit fabric with a thermochromic effect.

The thermochromic effect—color change triggered by temperature—has been known since the 19th century. However, its practical application in inks and dyes only became possible in the 1970s, when Japanese and American chemists developed leuco dyes capable of reversible color change within a narrow temperature range.
Thermochromic materials contain special pigments or dyes that react to temperature fluctuations. When heated or cooled, their molecular structure changes, altering the way light is reflected—what we perceive as a color shift.

Care instructions for dyed fabrics:

1. Wash at temperatures no higher than 30°C on a delicate cycle
2. Use liquid detergents only; avoid bleach
3. Air dry naturally, avoiding direct sunlight and tumble drying
4. Do not iron
5. Thermochromic properties are guaranteed for up to 15 wash cycles
