The delivery was as always very fast. I've always ordered size L in the past. These sit relatively close, so I've decided this time for size XL = 9. When I opened the package, but the top undershirt was in Size 7. All other shirts were delivered in the desired size 9. Because the quality is very good good and it was always the right size in previous order, this one shirt is used simply as a "rag". Otherwise, a strong buy recommendation!
