Carhartt Men's Long Sleeve Pocket Henley

Is the fabric on this henley lightweight or heavyweight?

This is a true heavyweight 6.75-ounce shirt. Solid colors are 100% cotton jersey knit, which feels incredibly thick, durable, and structured. It's built to withstand rough abrasion on the job site while keeping you warmer than a standard t-shirt. (Note: Heather colors contain a cotton/poly blend to achieve their textured look).
