“extreme athlete” = very skinny - Virtus Outdoor Group Ruck Jacket - Men's

I fell for the marketing on this and a pair of the same brands pants and have the same issue, “extreme athlete” doesn’t mean fit, it means skinny. With the jacket my shoulders and chest fit great, but the arms stretch every last fiber to barely fit over my arms, like tingling hands tight when your arms are bent (but somehow it’s still loose over the gut?).

If you have a muscular build this brand is likely not your winner.
