The GOMA band is made in Italy, from strong, stretchy natural rubber, with a smooth "no holes" shape. The holes are deliberately tooled only halfway through the band, so you use the buckle to "punch through" a hole for the best fit... the rest of the band remains smooth and understated, with no holes showing on the top side of the band. The back is textured for better breath-ability. Completely waterproof: just wash with soap and water if it gets dirty.
