LL Bean Maine Guide Zip Front Jac-Shirt Primaloft Women's Regular size XL I wore it once but had to admit it didn’t fit me. Super warm and cozy though! I’d say it is TTS, my measurements should have put me in a L but I was hopeful since it was the last in stock. From LL Bean: This great-looking wool jac-shirt is lined with warm PrimaLoft insulation to go along with all the great benefits of wool. It's a great choice as an outer layer in cool weather or for wearing under a shell or jacket in cold weather. Body: 85% wool, 15% nylon. Lining & insulation: 100% polyester.
