Ichiban is Ichiban like the Matuse Tumo front-zip series of Fullsuits built with Matuse’s Limestone #Geoprene. The Tumo is warmer, lighter, dries faster and lasts longer. Additional features include Hydrasilk Nylon, Satin Seal Taping, internal flood-bib, and an easy to access external key pocket. #makeitichiban #lovematuse #makeitichiban #da2006
