You asked, we found it. This premium heavyweight loop back sweatshirt knit is our heaviest sweatshirt fabric yet, offering exceptional structure, warmth, and durability. The looped reverse gives it a classic sweatshirt finish without a brushed fleece, making it ideal for year-round wear. Perfect for heavyweight hoodies, sweatshirts, rugby tops, zip jackets, and elevated leisurewear.
Pro tip: At 400gsm, this fabric becomes quite bulky when paired with traditional ribbing. For a cleaner finish, consider using the sweatshirt knit itself for the neckband, cuffs, and waistband instead of ribbing.

Fabric Care: Hand or machine wash in cold water with similar colours. Hang to dry and use a low iron if needed. We recommend pre-washing or pre-treating your fabric before sewing to account for any shrinkage. As always, use your best judgment and treat your fabric the way you’d want your finished garment to be treated - gently and with care!
