Got these for my husband at his request and he is super pleased with their fit, finish and performance. In regular shirt size he wears an extra large, so in these we ordered a large and they fit and work great for him. The v-neck is a plus because he doesn't like a crew neck as so many feel too tight around his neck. This brand is one of the few with the v-neck and quality made that I've found. Just ordered a third, three pack for my hubby. One thing I've learned over time and previous compression garments is to follow the laundering instructions tag. Shorter, gentler, warm or cold water and no fabric softener, dry on extra low or damp dry, no dryer sheets. Fabric softener/dryer sheets ruin the compression material pretty quickly. So big thumbs up for this this brand and shirts.
