Studio D’Artisan brings its signature denim heritage into knitwear with this heavyweight indigo rope-dyed thermal, combining traditional dyeing techniques with rugged, workwear-inspired construction. Instead of a standard waffle tee, this piece is knitted using extra-thick No.8 yarns, creating a dense, substantial fabric with real weight, texture, and long-term durability.

The yarns are rope-dyed in indigo, the same method traditionally used for denim. This process leaves the yarn core white while saturating the exterior with indigo, allowing the fabric to fade and evolve with wear, developing high-contrast highlights and character over time. The result is a thermal that ages more like a pair of jeans than a typical knit—personal, dynamic, and uniquely yours.

The heavy waffle (honeycomb) structure traps air for insulation while remaining breathable, making it ideal as both a standalone piece and a layering base. Construction is done using 4-needle flat seam stitching, ensuring smooth interior seams that sit comfortably against the skin while increasing durability.

Finished with ribbed cuffs, a one-wash treatment for stability, and made entirely in Japan, this thermal perfectly captures Studio D’Artisan’s philosophy: heritage craftsmanship, premium materials, and garments that improve with age.

Fit Notes: Studio D’Artisan thermals run smaller than standard American sizing. If you typically wear a size M in U.S. T-shirts, we recommend choosing a size L in this model. However, fit may vary depending on individual body types, so we always suggest referring to our size chart to ensure the best fit.
