CAT Men's Hooded Flannel Snap-Front Shirt Jac

How warm is this shirt jac?

It's insulated with 80 gsm recycled polyfill behind a quilted lining, so it's a real warm layer for cold mornings rather than an unlined flannel. Warm enough as an outer layer in cool weather, and it fits under a coat when it gets colder.

Is the insulation recycled?

Yes — the polyfill is 100% recycled polyester, so the warmth comes from recycled content rather than virgin fill.
