Ed, if you mean Supprescent by Goretex, it is very similiar to ScentLok and Scentblocker except Goretex imbeds their carbon. Supposedly it will not wash out or fall out! Although Scentblocker is supposed to contain more carbon, pro shops have told me that Scentblocker will lose effectiveness over time while Supprescent by Goretex stays the same. This coming from proshops who sell more Scentblocker than either!!!

Supprescent is also available in tops and bottoms that go under your regular camo. Bass Pro was selling the undergarments but have sold out I think. Browning and Whitewater Outdoors are two big companies making camo clothing out of Supprescent, along with some others.
