Review on Men'S Perfect Slim Fit V-Neck Sweater: Lightweight, Breathable, Soft And Fitted Pullover For Comfortable Wear by Jacob Sampino

These are very high quality sweaters that work well for going over button downs. I've had some that stretched out way too much or let the lighter shirt shine through, these block out the undershirt and allow a good contrast and comfy wear. They are also long enough for my arms even after washing and drying.
