With the Women's Neo Power Motion Bib, compression is the key word. But what is the advantage of compression? First, it increases blood circulation in the muscles; good blood circulation during long rides allows better performance and increases resistance to fatigue by up to 10-20%. Second, it helps prevent muscle vibration which causes additional fatigue and soreness. The shorts of the Neo Power Motion Bib are made with Power + LYCRA fiber which offers great stretchability and compressive properties. In addition, a women's Powerband at the cuff reduces lower leg pressure and provides support without restricting circulation. The women's Motion Airgel chamois completes these shorts designed for optimal comfort and efficiency on long rides. Louis Garneau Neo Power Motion Bib Shorts - Women's Medium Black
