To keep your Sweatshirt looking its best wash it in the machine inside out at 30° maximum. To maintain dazzling colours, do not mix whites with coloured clothes. Better than machine dry, prefer an exposure in the open air (dryers tends to shrink the cotton). Iron at a moderate temperature and turn the garment inside out to avoid damaging the design (especially do not iron directly on the printed zone!).
Do not use bleach or aggressive detergents, do not dry clean and do not remove stains by rubbing with abrasive materials. For a long lasting lifetime, pre-soak it in cold water for a few hours before wearing it the first time. This technique allows to fix fibers, size and colors!
