Arin

€ 92,00

Made for speed. As it’s name suggests in the Basque language, this fin has being made for achieving extra speed in your twin fin and feeling it light and easy to turn.

Designed for high-performance twin fins (narrow and thin tails), this fin combines speed and drive for every kind of wave. The fin is taller and thinner than it’s older brother, the Duette, and a straighter outline offers extra speed. The concept of the upright template is to perform fast through directional changes.

If you normally ride thruster boards and you want to try something more loose, this fin is made for you.

Construction: Fiberglass

Feel: Upright

Flex: 2/5

International Shipping

We ship anywhere outside the domestic Spain using DHL. Rates are exclusive of taxes, duties, and customs fees. DHL also requires that the recipient is responsible for customs duties and taxes. We are not able to determine import taxes, as they depend on a number of factors including but not limited to country of shipping destination and product price.

We cannot guarantee delivery time as it depends on how efficient your country’s customs agents are. All international packages are trackable once they are scanned in by the postman. More on that here.
