Usually when I got a 3XL of these as undergarments for rain pants to hike in, they were borderline comfortable on the obsessively snug end. 6 months later of consistent hiking every day and dumping down, this new brand fits extremely well, still holds, but if you're out for exercise daily and at my spec level in the title, be ready for 2XL a few months later. Really feel like I'll be pulling these back up frequently during hikes in 2-3 weeks, everything feels just right when it's new. 2XL would be uncomfortable at this time.
