How to read a blend of bamboo viscose and cotton
Short answer: A blend gives a bit of both. Cotton adds robustness and shape retention, bamboo viscose adds softness and moisture transport.
Why blend at all
Pure bamboo viscose is soft but slightly weaker when wet. Cotton makes the fabric more robust in the wash. See bamboo t-shirts for men.
What you lose
The more cotton, the less of that smooth, cool feel. At half and half it mostly reads as cotton. See bamboo underwear for men.
Look at the percentages
If bamboo viscose comes first with a high percentage, it drives the properties. If cotton comes first, it does. See bamboo clothing for men.
