Stevenson Overall Co Heavyweight Thermal Sweatshirt (Black)

Size Guide
Vintage masters SOC have delivered us another classic staple with their latest heavyweight thermal sweatshirts!

This shirt ticks all boxes in terms of vintage-inspired design and superior Japanese craftsmanship. The cotton fabric is what SOC calls an 'Air Spun Yarn', which is slowly woven using vintage thermal knitting machines. This highly-textured fabric is almost twice as thick and heavy as regular thermals. This thermal is sturdy and resistant to over-stretching so that you can enjoy wearing it for many years to come! Thanks to the natural over-dyeing process, you can expect this to age to a soulful look with time, with strong, vertical textures appearing!

Classic vintage-spec ribbing fabric has been used for the sleeve openings, shoulders and crew neck to keep you comfy and cosy while protecting you from the elements!

The fit is relaxed while still being elegant with a sharp look!

If you are looking for some high-end, vintage-inspired cotton thermal sweatshirts for the colder season, SOC could be the perfect choice!

  • Japanese heavyweight thermal knitting (slowly woven from the vintage machine)
