A new generation of men's underwear

Claesen’s No.1 products are proudly made of Pima Cotton. This type of cotton is named after the Pima, a group of American Indians.
Pima cotton is a type of high quality cotton originally grown in Peru. Its history spans centuries with first cultivations dated around 4200 bc.

Wearing genuine Pima cotton is a very unique experience.

Pima cotton is particularly sought after for its extraordinary fiber length of up to 42mm. Pima cotton fiber
lengths can be more than double the length of those of standard cottons, a fact that gives Pima cotton some distinct and very desirable qualities.

Longer fibers produce stronger and finer yarns by allowing the fibers to twist around one other more times.
Peruvian Pima cotton is thus known for its silky softness, its durability and its resistance to pilling. Furthermore, Peruvian Pima cotton is still
hand picked resulting in a brilliant white shade that can be easily dyed. The climate and soil conditions of Peru are perfect, with ideal seasonal rainfall,
long sunny days and high temperatures.
