Description
A long-sleeved koi-patterned rashguard, black ink enhanced with red and gold on a white background, with black side panels. Compressive fit, UPF 50+ protection.
UV protection integrated into the fabric
The knit is UPF 50+ certified: it filters ultraviolet rays without the need for sunscreen or constant reapplication. This is the ideal garment for long sessions in the sun, whether on the water or on the sand.
A print that won't flake off
The pattern is achieved through sublimation: the ink penetrates the fiber instead of sitting on top of it. There is no added thickness to the touch, no cracking, and no color fading after dozens of washes.
Structuring side panels
The sides are made from a contrasting black fabric. This limits the number of seams along the flank, where the arm rubs, and structures the silhouette.
Four sizes, from M to XXL
The sizing grid is based on chest circumference: 86 cm for M, 90 for L, 94 for XL, and 98 for XXL, with a length of 65 to 71 cm and sleeve lengths of 58 to 61 cm. The full guide is included in the product photos.
For what uses

Frequently Asked Questions
What is UPF 50+ protection?
It's a rating of how well a fabric protects against ultraviolet rays. A UPF 50+ fabric lets through less than one fiftieth of UV rays on the areas it covers. It does not replace protection for your face, neck and hands.
How do I choose my size?
The size chart is based on chest circumference: 86 cm in M, 90 in L, 94 in XL and 98 in XXL, with a length of 65 to 71 cm. The cut is compressive: if you want a looser fit, go one size up.
Does the pattern fade in the wash?
No. It's sublimation printed: the ink is embedded in the fibre rather than sitting on the surface. Still, dry it in the shade to preserve the vibrancy of the colours.
Can it be worn at the gym?
Yes. Many people use it for grappling and grip sports, where it protects the skin from mat burn, or simply as a long-sleeve compression top.
