Touchscreen Design and Anti-Slip PU Palm: These heated gloves feature touchscreen functionality with conductive leather applied to the index finger, allowing operation of smartphones, tablets, and other devices without removing the gloves. The non-slip PU palm material provides enhanced grip, ideal for driving, cycling, skiing, and motorcycle riding in cold weather conditions. Gloves are water-resistant but not waterproof; do not submerge in water or expose to prolonged soaking.

The advanced heating system ensures warmth reaches the fingertips, keeping hands comfortable during extended outdoor use. Ideal for winter activities such as skiing, snowboarding, snowmobiling, climbing, hiking, hunting, ice fishing, dog walking, and daily work in cold environments.
