I'm 6'3'' and 175 lbs. What size should I take? On their website they have sizes for taller guys with indication that these sizes are for the guys up to 6'.
ChunkyAt 175 lbs. you're exactly between a M and a L in the regular (not tall version) sized jackets, so I'd size up to properly accommodate for your height.
ChunkyI'm 6'4 180lbs and I have one XXL MA1 from alpha. The sleeves are tad long but everything else is perfect. I would say go for the XL for better fitment.
