I'll get on my soap box. There are two suits worth buying: Seaskin and SF Tech. Everything in the middle is a creative marketing exercise. Seaskin has quite a following here and while I have not dove those suits, I know people who have and I've inspected the suits in person. They're the most unbelievable value for what you pay.Is there a reason? Mainly cost? And is it as durable as the suits double its cost?
SF Tech will run you 4x that price but no DUI, Santi, Waterproof, and other mid-market players will get to the quality of a custom-made Swiss suit.
