The genuine LL Bean field coat is the one to get. I purchased this as a Christmas gift for my son-in-law. A big hit. Top quality. He really liked it. Generally he's a large because he has broad shoulders, but had to size down to a medium in this. HIgh recommend.
My husband loves his new field coat. The quality is excellent & very stylish. I was amazed at how quickly it arrived. I'm very impressed with the product and L.L. Bean.
