What are the major differences between these products. I realize they both use carbon, butt the suits appear to be different to me.

If I may, let me compare apples to grapes. First I'll say I'm not a huge believer in scent lock but both the products I bought I would have bought anyways and scent lok or scent blocker were just as cheap.

For scent blocker I bought a pair of fitted gloves. The carbon seems to be loose and it actually turns my hands black when I wear them.

For scentlok I bought a full head face mask. The carbon is woven right into the fabric and it dose not turn my face or head black when I wear it.

I know this probably dosn't help too much but this is the extent of my experience with the products. Hopefully it wil help some.
