Bamboo viscose versus merino wool
Short answer: Merino insulates better and smells least. Bamboo viscose is softer against the skin, cools better in heat and costs less.
Warming versus cooling
Merino wool holds warmth even when damp, which is why it is standard in winter base layers. Bamboo viscose leads heat away from the body and is therefore better when it is warm indoors or out.
Odour over several days
Merino can be worn for days without smelling, because wool binds odour compounds. Bamboo viscose needs washing more often. For travel without laundry facilities, that favours merino. See bamboo undershirts for men.
How it feels on the skin
Bamboo viscose is smoother and softer and never prickles. Merino can feel rough to some people, especially at the neck and the underside of the arms. With sensitive skin, bamboo is the safe choice. See bamboo underwear for women.
Care and price
Merino needs a wool wash and does not tolerate a dryer. Bamboo viscose washes at thirty degrees like everything else. Merino usually costs more per garment. See bamboo clothing for men.
