Men's Jammers Selection Guide
Q: What are the advantages of jammers compared to briefs in terms of swimming performance?
A: Jammers provide better muscle compression effect, which can effectively reduce the vibration of thigh muscles, reduce water resistance and improve hydrodynamic performance. For speed swimmers or swimmers who need to train for a long time, Jammers can provide better support and coverage.
Q: How to choose the size of Jammers? Will being too tight affect blood circulation?
A: Professional Jammers should feel "snug" rather than "tight". The correct size should hug the muscles tightly but not create deep indentations at the waist or top of the thighs. If you're hesitant between sizes, choose the comfort size for training and the tighter size for racing for optimal compression.
Q: What is the difference between Jammers for training and Tech Suit for competition?
A: The training style emphasizes chlorine resistance and durability and is suitable for daily use; the competition style ( Tech Suit) uses extremely high compression fabrics (Tech Suit ) uses extremely high compression fabrics (such as carbon fiber or special coating) to minimize resistance, but has a shorter lifespan and is more difficult to wear. Dolphin eShop offers both to suit different stages of needs.
