I was pleased with how quickly (with international shipping) they arrived These briefs seem to be well constructed of a breathable wool cloth. They are not traditional Y-fronts; they are made with a pouch but no "pass-through". I am not slim. I ordered these briefs because they were available in XXXL size. Around the same time I purchased wool briefs from two other companies in size XXL (the largest they offered). The EDZ briefs are distressingly snug, noticably smaller than the other two. I am very disappointed in the size of these briefs.
