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 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.

Rated 5 out of 5 by from Comfortable and warm Just like the shirt these pants are flexible and warm. Wore these under my voyage suit during 30 degree morning high of 50 day and was comfortable didnt sweat and didnt get cold. Highly recommend these baselayers i would say the sizing runs true im a 42/44 waist snd the 2xl fits nicely.

Rated 1 out of 5 by from Product Size Availability is Poor It would be nice if you have 2x or 3x sizes available for most products and not just random items

Rated 4 out of 5 by from Performance of the scentlok Trek base layer bottom It’s very nice to wear and scent free but it’s not as warm as I hoped. It was 50 degrees out and my legs got cold under the Scentlok Cold blooded pant so I returned them for a refund. However they are probably great for early season hunting

Rated 5 out of 5 by from Great baselayer I purchased this for late season sits and again glad I did! I was able to layer down and these pants are warm, soft and comfortable. They were a little shorter than expected but that won't effect my rating! Great baselayer
