Industry Leading Carbon Alloy Technology



Our industry leading technology combines activated carbon, treated carbon and zeolite concealed between fabrics. The massive surface area of these natural particles target and adsorb odors and won't let go until you reactivate your gear in your dryer.

Moisture wicking fabrics



Wicking technology draws sweat away from the body toward the outer surface of the fabric for quick evaporation. Using hydrophilic (water loving) and hydrophobic (water repelling) fibers, pathways are constructed within the fabric that help the moisture move.

Fusix is printed coat of engineered carbon that will not wash out



A printed coating of engineered carbon (gold hexagons) fused directly onto the fabric that provides an additional layer of permanent odor protection. Fusix can be implemented onto certain fabrics that other scent control technologies cannot, allowing for more versatility and mobility.

Silver Alloy is permanently embedded into the fibers and will never wash out



Silver technology permanently embedded into co-extruded fibers that control the growth and sustainability of bacteria in the harshest environments. This implementation method ensures the technology will not wash out and lasts the life of the garment.

Rated 5 out of 5 by from Great Product!! These Merino Wool Scentlok base layers are awesome! If you have a hard hike in to your stand and get all sweaty…it’s not a problem! These base layers wick the sweat away from your body keeping you warm BUT they don’t let odor get you busted!! I’m hunting on the ground this year and twice now I’ve had 2-3 year bucks less than 10yrds away and didn’t get my wind! Sizing is accurate. They are super comfortable.

Rated 2 out of 5 by from Not worth it. Runs big. I'm 6'2 230lbs and I bought the XL. They could fit two of me in them. I had the same problem with the top. I returned them both, and tried different sizes that ended with the same results. I would not buy this product because the sizing is totally off. A base layer is supposed to be snug fitting but still allow you to move freely. In my opinion they missed the mark on this product. I currently own other Sentlok base layers that are far superior, and cost half as much.

Rated 1 out of 5 by from Absolutely terrible base layer! I’d give it a zero if that was an option. The fit is absolutely awful! I have never had any base layer that was a baggy fit. I have always ordered size large base layers because of the snug fit that you’d expect from a base layer. These are nowhere near being a snug fit! Glad I got them on end of season clearance sale and not at full price. Will not be wearing them other than the three hours I did for one sit.

Rated 1 out of 5 by from Good attempt. Priced right. Bad fit. Several problems with sizing and overall comfort. Waist elastic is for someone much larger than 33-34 waist. Crotch area isn’t right. It’s too short so you feel the need to pull the item up. Layered this will be very uncomfortable. When sitting and standing it will come down naturally. More discomfort. And finally. It’s not very snug.

Rated 4 out of 5 by from XL is TOO Big! Excellent quality, but I only give it a 4/5 because an XL was much bigger than I anticipated. I've purchased many ScentLok items as well as a variety of other hunting and fishing clothing items through other vendors/manufacturers, and haven't ran across such a size disparity. I would advise to buy a size smaller than you normally would.
