I am not a small guy. 6'3 and 290 lbs with a 36 inseam. My mid section is well fortified but short. Its hard to find shirts to fit because of my belly requires them to be longer. Although I am currently addressing that issue as best as possible I need some base layer shirts to fit for my summer rides. I am a 2xlt or 3xlt depending on brand. Thats the only way to get them to tuck in. Anyone come across a brand that is hefty friendly with their under shirts?
