The Klimatex CHER women's briefs are made of a microfibre polyester with Lycra. Micro-fibres provide a larger surface area and inter-fibre space in the knitwear to allow sweat wicking. The sweat that evaporates from the fibre surface can be drained much faster. The material is also more pleasant to the touch. The briefs feature a wide elastic at the waist with the brand logo and flat seams.
