Yamamoto: the brand behind the brands

To the wetsuit shopper just beginning their journey, one name keeps recurring: Yamamoto, and for good reason. Founded in 1961, the Japanese manufacturer is the standard bearer for the neoprene (a rubber) used to construct the most popular triathlon wetsuits on the market.

Made from Limestone (as opposed to petroleum), Yamamoto neoprene provides it all: insulation, buoyancy, and stretch.

Yamamoto presently has 4 versions: 38, 39, 40, and 44.
