Bamboo Boxers are our top selling style. Our bamboo viscose fabric is very light and super soft.  Our bamboo boxers are offered in the relaxed fit (classic style) and also boxer briefs. The fabric will feel closer to cotton, but is much softer and cooler than cotton.Performance boxers are also a relaxed fit /classic style. We use our unique blend of Polyamide/Nylon and Spandex. This fabric is also very soft and cool with micro perforations for added breathability.  The fabric feel is more like high performance golf shirts or yoga pants.Both are great options :)We are striving for lifelong customers, so if you are not happy for any reason, we will accept returns and exchanges.
