The Marmot Silkweight Crew SS Shirt is an ideal high performance base layer or on its own for warm weather activities such as backpacking, hiking, climbing, trail running, etc.
Silkweight Infinity will keep you warm, dry and odor-free permanently. Marmot's BacteriaStat with Anti-Microbial Yarns use a non-migratory silver ceramic polymer additive that is embedded into the polymer matrix of the polyester yarn before extrusion, finishing and knitting. The Silver Ions from the ceramic polymer of BacteriaStat shut down the the breeding process of bacteria to eliminate odor but cannot migrate to the skin.
Marmot DriClime denier gradient, plaited knit fabric that mechanically wicks moisture from your body and allows it to evaporate away from your skin to keep you dry and warm. Crew neck provides a comfort fit. Tag free neckline eliminates the desire to reach back and rip out an itchy tag. Shaped fit reduces bulk for layering.
*The History of Silver as an Anti-microbial Agent
The use of elemental silver as an anti-bacterial agent is nearly as old as the history of mankind. The ancient Egyptians mention the medicinal use of silver in their writings. Romans stored wine in silver urns to prevent spoilage. The courts of the Chinese emperors ate with silver chopsticks for better health. Druids used silver to preserve food. American settlers put silver dollars in milk to stop spoilage. Silver leaf was used during World War One to combat infection in wounds.Today, silver is used to treat serious burn victims, to sterilize catheters, to control bacteria as a disinfectant in fast-food chains, to filter and destroy airborne bacteria, to purify spas, pools, and municipal and airline drinking water systems, to control disease in shrimp aquaculture, and to topically, intramuscularly and intravenously kill antibiotic-resistant bacteria, virus and fungus in humans and large animals. NASA tested 23 different methods of purifying water for the space shuttle and selected a silver filtration system. Human skin has many surface bacteria present at any time; that is not a bad thing. During use, this surface bacteria transfers to textiles worn next to the skin. There, in a warm, dark and moist environment, the bacteria breeds, particularly after aerobic activity. Sweat and sweaty clothes smell because it contains bacteria effluent like ammonia. Anti-microbial agents in clothing can destroy these bacteria and prevent the breeding process.However, anti-microbial clothing must strike a balance to be both effective and safe. A migrating anti-microbial can destroy everything it contacts, including the good and necessary bacteria needed for healthy skin. The balance is to destroy the bacteria in the clothing, stop the breeding process but to leave the skin bacteria intact. |
