CottonMill Sweatshirts - These are the thickest and softest 100% Cotton Fleece 3-Button Polo around! Heavy weight cotton makes these 100% COTTON sweatshirts super warm and thick. And, they are MADE IN NORTH AMERICA, in CANADA. Although this item is 100% Cotton, there are trace amounts of lycra spandex in the trim.

The 100% cotton fleece is made with an inner twill placket and smooth flatlock seams. Shrinkage is almost totally eliminated during the dye process, which also reduces twisting and pilling - producing a stable and consistent fit. These Polos are known for a very generous fit and they have durable ribbing at waist and cuffs. This ribbing has traces of Lycra Spandex that provides the stretch. Sizes S to XXXL. These sweatshirts are wonderfully cozy, and all pure cotton. Made in Canada! Note: Although this item is 100% Cotton, there are trace amounts of lycra spandex in the trim.
This hoodie is designed to be worn often and washed regularly without losing its shape or comfort. From workdays to weekends, early mornings to long nights, it’s a dependable layer that feels substantial without being restrictive. Comfortable enough to lounge in, durable enough for everyday use.
CottonMill Hooded Sweatshirts — thick, breathable, and built to last. If you’ve been disappointed by “cotton” hoodies that still feel synthetic, this is the difference you’ve been missing.
Cotton Mill garments are intentionally heavier than typical retail sweatshirts. If you are used to lightweight sweatshirts from mall brands expect: more density, less stretch, a thicker structured fabric rather than a thin drapey fit.
Choose your size using the Fit Guide, then confirm with the Actual Garment Measurements.
Cut in generous UNISEX sizing for a relaxed, comfortable fit. If you prefer a closer, more fitted feel, consider sizing down.
Note: Females — chest is not a band measurement.
