I picked up a new FJ sweater earlier this year and I must say that I am so very impressed with it.
The styling is classic yet with a contemporary look and is constructed of 100% wool. The sweater is a half or quarter zip mock neck with ribbed cuffs and ribbed neck for a snug yet comfortable fit. I purchased the "Heather Blue" version which is very attractive and versatile as a staple in my golf attire - particularly for the cooler months. The contemporary styling, fit and looks means that this can also do more than just provide added warmth on the golf course -- after golf, I can slip into the clubhouse or a local pub with my playing partners and my sweater is a great piece that is never out of place.
I've worn my FJ Mock Neck base layer underneath it for warmth and layering and this sweater over top for a warm and stylish fit. The wool fabric is not too tightly woven together and is not particularly heavy weight so it is breathable, yet still offers some warmth. Using a layered approach helps keep me warm when I'm facing some cool breezes while not overheating when the clouds part and the sun shines down. It's a great piece for the fall and early spring season.
