Oh swimming. With 85% of triathletes coming from a running, cycling, or other background, it’s no wonder so many people fear this leg of the race the most. If swimming isn’t your strength, blue seventy has an answer. The Axis. Blue Seventy has recognized the fact that there’s different needs for different types of swimmers. Some athletes have denser leg compositions due to established thigh muscles and dense calves. Many of these swimmers tend to drop their lower half in the water. Thus, the Axis was innovated with balanced buoyancy zones. This suit in particular focuses higher buoyancy in the hips, thighs and lower legs.
