UFM Bamboo Spandex material is designed to provide the soft cottony feel, while still maintaining moisture management properties for anti-chafing. It is also the coolest choice for the warm weather. Choose bamboo for light everyday wear or light duty sports (ie golf). UFM does not offer actual cotton products due to their poor moisture management. Note-Cotton gets wet and stays wet causing chafe and other issues. This material also goes by viscose (made from bamboo)
Note: Bamboo Spandex is used in the body material only on the Trunks, Standard and Long Boxer Brief. The pouch design and material is the same between the bamboo and polyester options. It is a 4 way stretch polyester mesh the with the same support level.
Briefs feature solid Bambo pouch material the same as the body material.
