Xcel Thermoflex TDC free dive wetsuit (smart fiber lining yea or nay?)

Howdy folks, I'm in the market for a new freedive suit and was looking at a new one from xcel. It has this moisture wicking liner on the inside, I guess it's similar to hollow fiber. Now I know most free dive suits are open cell with no lining and I was wondering if anyone here has tried this new one from xcel or has any feedback on liner  vs no liner. Ive been using a 5mm xcel surf suit which works good but I start getting chills after 2 hrs in the water. thanks!
