I will agree with others where they say this runs small(er). Comparatively, it seems to fit around the waist as the heatgear fitted tops. 'Loose fit' as the page says, is a poor descriptor. While the material is light and stretchy, it doesn't lay flat on the chest, particularly close to the collar bone. It's either too far pulled back, or too far forward. I have to keep adjusting so it doesn't look awkward. If one has a more V like torso, I will mention it might reveal more than one might be comfortable with for the chest; especially on a profile view. The back imo looks great, and was the main reason I chose this top. Unfortunately, I'll be returning mine. If the front covered more of my chest, and didn't require me to adjust, it would've been perfect. Can't comment on gym functionality. Added pics for reference
