Storing your gear in a ScentLok pack is an important step for success in the field. Every piece of gear you use picks up ambient odors from its surroundings and these can often be alarming to deer when you bring an unnatural smell to the woods. To achieve the best results in your hunt those odors must be minimized with odor controlling sprays and storage. 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. DWR, or durable water repellent, is a fabric finish that helps repel light rain and snow. It keeps the top fabric from becoming saturated while also decreasing the amount of time it takes for the fabric to dry, keeping you comfortable and dry. ScentLok Technologies is a leading worldwide designer of performance, hunting and casual odor-controlling apparel, footwear and equipment. ScentLok is the only company with access to all scent-controlling technologies including their patented activated carbon technology, which is consistently proven to outperform other technologies tested.
