Bamboo viscose versus pima cotton

Short answer: Pima is cotton with extra long fibres, giving a softer and stronger fabric than ordinary cotton. Bamboo viscose is still smoother and cooler.

What makes pima different

Fibre length decides how soft and strong a yarn becomes. Pima has markedly longer fibres than ordinary cotton, so the yarn has fewer protruding ends and is more even. That is why pima feels softer.

Where bamboo still wins

Bamboo viscose is a filament fibre in its basic form and therefore has a smooth surface with no fibre ends. It also conducts heat away from the skin better. On hot days and in underwear the difference shows. See bamboo underwear for men.

Where pima wins

Pima is stronger, holds its shape better and survives more washes. For a t-shirt that should look the same for years, pima is a solid choice. See bamboo t-shirts for men.

Blends give you both

A fabric of bamboo viscose and cotton combines softness and strength. Many basics are built exactly that way. See bamboo clothing for men.
