We recommend on the 1st washing, to wash warm, and lay flat to dry. Your cotton sweatshirt will dry in a few hours. After drying you can put in dryer for a few minutes to soften. This will control the shrinkage during the 1st washing cycle. When worn, the fabric will "relax" and give back about 1/2 what was lost in the shrinkage. The sweatshirt will only go through this shrinkage cycle one time. High heat will dry out cotton fabric. We recommend laying flat to dry your heavy cotton sweatshirt.
The sleeves on Kellsport sweatshirts may appear very long before the 1st washing. That is because the grain of the fabric is going vertically down the sleeve. Expect the sleeve length to shrink 3"-4" on the 1st washing.
After the 1st washing there is no need to "baby" your new sweatshirt. Wash and dry any way that you prefer.
