How to Care for Heavyweight Cotton So It Lasts

A few small habits keep a 240 or 350 GSM piece looking new for years — colour, shape and all.

Heavyweight cotton is built to last, but how you wash and dry it makes a big difference to how it looks a year from now. Here's the routine we recommend.

Washing

  • Turn garments inside out to protect the outer surface and any print.
  • Wash in cold or lukewarm water with similar colours.
  • Use a mild detergent and skip bleach — it weakens fibres and fades colour.
  • Choose a gentle cycle for hoodies and sweatshirts so the fleece stays soft.

Drying

  • Line-dry in the shade; strong direct sun can fade deep colours like black, maroon and midnight blue.
  • Dry heavy pieces flat or folded over a line to keep them from stretching lengthwise.
  • Avoid high-heat tumble drying, which is the main cause of shrinkage.

Ironing and storage

Iron on a medium setting with the garment inside out, never directly over a print. Fold heavyweight pieces rather than hanging them — hangers can stretch the shoulders of a 350 GSM hoodie over time.
