I am planning on buying this vest as a gift for my boyfriend but I'm unsure what size to get after reading some of the conflicting reviews of it being "slim fit" and "runs big". My boyfriend is 5'11" about 180-185 with broad shoulders and I know he is a 34 around the waist. If I order a Large will it be too big??
