100% cotton shirts tend to be heavier, softer, and preshrunk.
50/50 Cotton and Polyester blend are light weight and provide minimal shrinkage.
Brands themselves vary on how much they shrink upon washing. We recommend not using the Anvil brand if you need a true to size shirt with minimal shrinkage as our past experiences have shown some unpredictable shrinkage in some of the shirts we have used.
We stock shirts that we have personal experience with that withstand rigorous activities and still keep their shape and size. If there is a specific brand you would prefer, please email us and we can special order it for you.
