From AYR.com: Oooo this tee is so delicious you'll never want to take it off. It's made of Dime Knit™, our signature super satisfying heavyweight jersey. 100% cotton in a 10/1 singles weave, which means, in terms of heft, it's somewhere between a sweatshirt and a tee. Year-round cozy. The hem is meant to cover your bum and the sleeves are so long that your hands can turtle up in them. It's perfect for airplanes, chilly mornings, coffee mugs, and cool nights. Oversized fit, excellent like new condition. Worn and washed only once.
