Optics Planet has the Scentblocker Men’s Performance 1/4-Zip Sweatshirt on sale for $29.99. It includes a travel bag with shampoo, bodywash, and a razor. Use the code WORK7 to get an additional 5% off, bringing the price down to $28.49. Shipping is free when you order $50+. I looked for quite a while trying to get more info on this performance top, but information is very limited. My best guess is that it is 100% polyester and is very similar to the knockout line. I believe the lack of info is reflected in the price and it’s a deal regardless of the fabric. It is available in Realtree Xtra and Max in sizes M-XL.
