High-performance Odor-Free, Long-Lasting, Anti-Bacterial Base Layers

The secret is in the fabric. Propper base layers feature a Polygiene® treatment that incorporates silver salt (silver chloride) into the weave of the fabric. Polygiene prevents the growth of odor-causing bacteria and fungi at the source, permanently. Not only does it prevent odor, it also extends the life of the garment by preventing bacteria from eating away at the fibers over time (think holes in socks).

The performance of these base layers goes beyond the fabric. Propper utilizes flat-lock seams to lay flat against the skin to avoid rubbing or chafing. These flat-lock seams are sewn offset from the shoulder for increased comfort. This is beneficial when carrying a bag or wearing armor that would ride on the shoulder and dig a traditional seam into the skin.
