The concept of low modulus is proposed by SUMARPO for the first time in the field of triathlon. Using low modular technology(LMT) can reduce physical consumption and improve the efficiency of swim stroke. For instance, swing the arm 300 times in the same unit, the LMT material consumes less energy. By adopting the LMT tested hundreds of times, 1.5mm Yamamoto #40 neoprene with the 630% highly SQ flex liner in the arms and shoulders. Move without any fatigue, just like your second skin.

100% LIMESTONE NEOPRENE

Premium Yamamoto neoprene is derived from limestone instead of petroleum. Unlike NR (natural rubber), limestone neoprene is a kind of CR (chloroprene rubber), excluding allergens and carcinogens, which is totally healthy for human-being. The exploitation and production process is eco-friendly, with renewable energy sources such as hydroelectricity.

Made from fibers certified by OEKO-TEX Standard 100, these recycled & degradable lining fabrics are born from nature and able to back to nature, which helps to protect the environment.
