Wrap yourself in pure comfort with this long-sleeve women's pajama set from Japan. Made from 100% Tenwata cotton, a rare, premium extra-long staple cotton knit into a smooth fabric, this set offers an exceptionally soft, silky texture against the skin. It earned the top sales spot on Wacoal's Web Store in 2025, and it's easy to see why: a cozy long-sleeve top paired with full-length pants, made for effortless bedtime relaxation.
This nightwear set comes from Wacoal's Suimin Kagaku (sleep science) line, a collection built around the idea of turning sleep time into dream time. Wacoal designs its sleep items to help enrich daily life through deeper, more restorative rest.
A matching men's version of this Tenwata pajama set is also available, crafted in the same high-quality style.
