This beautiful thermal makes a striking impression at first sight, thanks to its premium double-face jacquard fabric with a unique vertical-ribbed knitted structure. The material takes inspiration from 1960s military thermals and boasts an uneven warp and weave structure, while the lining features a needle weave texture that feels cozy against the skin.

It's a layer worth putting on as a standalone piece during spring and the beginning of autumn or as a hardworking layer beneath your clothes. It can make all the difference between a harsh winter and a bearable one. The slim cut enhances heat retention and helps maintain your body temperature. This heat retention capacity is comparable to that of the best technical shirts, with the added benefit of being made from 100% natural cotton. This sturdily-constructed cotton thermal is as traditional as can be.

It features premium details that require a lot of time and effort, such as vintage-style ribbed cuffs and a rounded overlock back hem. In addition, a vintage Union Special 4-needle flat seam machine is used to construct the garment with 100% cotton thread, eliminating irregularities in the seam allowance. Like many other Japanese garments, this sweatshirt runs a bit smaller in size compared to your regular American size. However, individual body types can vary, so, as always, we recommend consulting our size chart for the perfect fit.

For the absolute best of the best, look no further than Japan's Loop & Weft, who have been crafting top-tier tees and knitwear with an artisan's eye for more than a decade. Using rare vintage machines, their pieces undergo a tediously slow knitting process that results in incredibly dense and suspiciously soft fabrics with unique uneven textures derived from the combination of natural and recycled fibres. In their efforts towards eco-conscious production, they use natural dyes with low environmental impact, resulting in coveted, one–of–a–kind pieces with a trademark organic unevenness in colour.
