The Mesh-Tech Armour Top is made of a wicking material so can absorb any sweat or moisture accumulated throughout the day. For this reason, we highly recommend these tops for outdoor people who like to get in the thick of the action, but want to remain calm, cool and calculated throughout. There is a thin neck collar and long sleeves to protect slightly more flesh than the 'Mesh-Tech Armour T-Shirt', at the cost of being a bit warmer. Being comfortable in your equipment is half the battle of staying effective in the field and pouring with sweat will only limit your performance.
