What Is the Best Bamboo Fabric for Underwear?
Recommended constructions for ladies' and men's underwear: 95% bamboo 5% spandex at 150-210 gsm with Ne40/1 or Ne32/1 yarn and 20D or 30D spandex, in 165-170 cm width.
Softness Is the Priority
For underwear, softness against the skin is the most important property. Bamboo fiber delivers that better than cotton at the same weight, which is why it dominates this category.
Ladies' Underwear Fabrics
The common construction is 95% bamboo 5% spandex:
| Weight | Yarn Construction |
|---|---|
| 150 gsm | Ne40/1 + 20D spandex |
| 160 gsm | Ne40/1 + 20D spandex |
| 190 gsm | Ne40/1 + 30D spandex |
Men's Underwear Fabrics
Most men's programs use 95% bamboo 5% spandex at a heavier weight:
| Weight | Yarn Construction |
|---|---|
| 190 gsm | Ne40/1 + 30D spandex |
| 210 gsm | Ne32/1 + 30D spandex |
Some programs use 68% bamboo 27% cotton 5% spandex at 190 gsm (Ne40/1 + 30D) or 210 gsm (Ne32/1 + 30D). Adding cotton improves durability and reduces cost while keeping bamboo as the dominant skin-contact fiber.
Width
These fabrics are commonly 165 - 170 cm wide.
