Chad is correct. We offer floatation in 6mil, 9mil, 13mil, and 20 mil. Up until this year, all of our men's vests were 13mil front and 13mil back. Due to the popularity of the Platinum series, which we made 13mil front and 20mil back, I decided that the 2014 line would come standard 13/20. Women's vests have always been 13/20. Shorter & smaller bodies need thicker since they don't have the length. Most top ranked skiers want a vest as light as possible and have never complained about the 13/13. The platinum vests definitely stay the lightest and seem to dry out instantly. Our padding is sewn in so it won't float or move on you even after countless sets. It costs a lot more in labor to sewn each pad like we do. We must first bevel the edge of the foam, then apply an light adhesive strip to keep it in place, and then make sure the sew lines are accurate. Very time consuming! 80% of my cost is labor. Most vest manufacturers sandwich the foam between two layers or neoprene and quickly sew around it. Once the padding flips inside the cavity, it's a pain to get it back into place. We make a lot of custom vests (colors, sizing, and custom padding). Just contact your Eagle dealer and explain what you're looking for and they'll get it into the works for you. We definitely appreciate the support you give us. We're committed to being a US Made manufacturer. ...Chuck
