Material and Comfort: What to Expect from Each
I've handled both in a print shop, and here's what you should know:
Hoodie - 80% cotton / 20% polyester blend. The interior is brushed fleece, which traps heat effectively. Great for 40-60°F days. The downside? It can feel bulky when you're indoors or layering under a winter coat.
Crewneck - 100% cotton ringspun fabric. The french terry construction is breathable and drapes nicely. It's lighter, so you can wear it from fall through spring. The lack of a hood means no bunching around the neck, and it dries faster if you sweat.
In a side-by-side test, the hoodie kept me warmer by about 5 degrees, but the crewneck was more comfortable for all-day wear at a desk.
