Pro Tips for Ultimate Warmth:
- Keep your core warm with our BasePro or Jacket for full-body heat retention.
- Stay hydrated to help regulate body temperature and maximize your comfort.
- For the best performance from our socks, we recommend pairing them with our BasePro layers or jackets to maximize warmth. We're also updating our online info to emphasize that keeping your core warm first is the key to preventing cold hands and feet.
NEW IMPROVED DESIGN AND FIT
Men's Sizing: S: 5-6, M: 6-8, L: 9-10, XL: 11-13.PLEASE NOTE: For those with sensitive feet, we recommend wearing a thin wool or Merino non-cotton sock as a first layer under the SockPro.
