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 A must have I just got it in the mail and as soon as I put it on I was super impressed. Its light feels great and fits true to size the back stretch panel and tagless design and the warmth it’s going to add in the fall is a no brainer

Rated 3 out of 5 by from Good quality, poor fit. 6’2”, 220#, athletic build. After reading many of the reviews stating that this shirt runs short, I went a size up and bought the XXL. The arm length is still a little short (I have longer arms), but the body is now way too wide. So, the fit is off. It is a heavier shirt than my previous base layer, and does seem warm as well.

Rated 5 out of 5 by from Worth every penny Just bought this shirt and pants last week and hunted the same day they arrived. The main thing I would say about this product is that it exudes quality. Looks and feels well-made, and worth the price. However, it does not fit snug against my skin. I'm 5'7", 140 pounds, and ordered a small. I often struggle to find gear that fits me just right, but have never had an issue with baselayers if I buy a size small. That said, I absolutely love this product and will wear it every chance I get.

Rated 5 out of 5 by from Base layer proves effective Bought the Clima Fleece Base Layer (Midweight Shirt and Pants) for late archery season and was very pleased as deer approached from downwind and did not get my scent. This happened repeatedly so it was no conincidence. Very pleased with this purchase and will be adding to my Scentlok wardrobe as money allows.
