TOO TELL YOU ALL THE TRUTH, IF YOU LOOKED AT SCENT LOK, AND SCENT BLOCKER BRAND, THE MAIN PART THAT ABSORBS THE HUMAN ORDER IS MADE BY JUST ONE COMPANY, THAT COMPANY IS "ALS ENTERPRIES, INC." SCENTEK ODOR ELIMINATION TECHNOLOGY. THEN SCENT LOK, AND SCENT BLOCKER PUTS IT INTO THERE CAMO PRODUCTS. LOOK AT EACH COMPANIES BROCHURES, YOU WILL SEE "ALS ENTERPREIES, INC." BOTH BROCHURES ALSO HAVE SAME PATENT NUMBERS.

I USE SCENT BLOCKER'S NOTHERN LITE, FOR THE FACT WHAT THEY HAD IN THE WAY OF JACKET/ BIB WAS A BETTER DEAL $$$ FOR ME AT THE TIME. EITHER ONE IS A GOOD CHOICE BECAUSE THEY ARE REALLY ALL THE SAME.
