How waterproof is this item?

GORE-TEX (GTX) is a high-performance membrane used in motorcycle clothing to protect you from rain and wind while still allowing your body to breathe. It is waterproof and windproof, and transports moisture away from your body. This helps you stay dry, comfortable, and protected in a wide range of conditions, from daily commuting to long touring rides.

The main function of GTX is to block external water and cold air without trapping heat and sweat inside your clothing. This balance between weather protection and breathability is what makes GORE-TEX one of the most trusted materials in premium motorcycle gear.

Depending on how the garment is constructed, the GTX membrane can be integrated in different ways, influencing comfort, drying speed, durability, and weight. In every case, the goal is the same: reliable waterproofing, effective wind protection, and consistent comfort while you ride.
