United StatesThe foundation rash guard runs quite small, not ideal for stocky muscular builds. Would love to have purchased a size or 2 larger.
United StatesThe rash guards are great quality overall, I'd just recommend sizing up. I'm 6ft and 175-180lbs and the large is extremely tight.
United StatesThe website is fantastic. The rash guard is not a good fit. I wear clothing in Large and XL. I bought a size XL rash guard and it is incredibly tight. It makes me feel like I need a XXL or XXXL to fit properly.
United States United StatesHello, unfortunately the rash guard is smaller than the medium I bought in the past even though it’s a large. I unfortunately can’t even wear it because it’s to skinny. I’m not sure if it’s supposed to be a large in children’s instead of adults.
