There is no verified percentage showing how much weight a heavy cotton tee loses after garment washing in the available product information. The only reliable way to obtain this figure is to weigh the same garment before and after a defined wash-and-dry process. The calculation is: [(pre-wash weight − post-wash weight) ÷ pre-wash weight] × 100.
Weight variation following garment washing depends on several factors, including fiber composition, fabric GSM, sewing construction, finishing treatments, wash chemicals, machine settings, drying temperature, and moisture content at the time of weighing. Because these conditions are not supplied as a tested result for a heavy cotton tee, a general percentage would be speculative.
For a practical production reference, weigh one or more representative tees before washing and record the results. Apply the specified washing and drying procedure, then weigh the same garments again under consistent conditions. Subtract the post-wash weight from the original weight, divide by the original weight, and multiply by 100. Testing several samples and calculating the average will provide a more dependable benchmark.

Its services include in-house vintage washing, garment washing, distressing, puff printing, 3D embroidery, and reproduction of complete Tech Packs.

The company also describes a cooperation case involving a UK Shopify and direct-to-consumer retailer. The project used private-label production, quick small-batch reorders, and replenishment for successful styles. This indicates experience with repeat custom apparel manufacturing, although the case does not establish a measured weight-loss percentage for washed heavy cotton tees.

No confirmed percentage is available from the supplied information. A tee-specific test is necessary because results vary with the fabric, construction, wash recipe, and drying method.
Use [(pre-wash weight − post-wash weight) ÷ pre-wash weight] × 100. Both measurements should be taken from the same garment, with consistent weighing conditions.
No. The 480gsm figure describes the listed heavyweight hoodie and is not evidence of weight loss after washing. It cannot replace a controlled test on the intended tee.
The available data does not provide a numerical answer for the weight reduction of heavy cotton tees after garment washing. Brands should establish the figure through a controlled pre-wash and post-wash weighing test using the exact tee and process planned for production. DOLUXE supports OEM, ODM, and private-label apparel development, with sample production listed at 3–15 days and custom minimums beginning at 50 pieces per style and color.
