Wow, sickest single ply shirt i have EVER used. it rivals my double rage-x in support. last night i worked off a 4.5" board and tripled 545, singled 585 easily and almost gave 635 a ride. My double rage-x barely got me to 585. This shirt is outta this world. Im doing a single ply meet in 4 weeks and im probably going to out bench my last meet i did in the double ragex.
