THE NORTH FACE Men's Thermoball Traction Mule V - Warm

In this review the Men's Thermoball Traction Mule V is judged as a cozy, easy-wear winter mule best suited for outdoor-oriented men who want insulated slip-in footwear for camp, cabin, or quick errands. The single biggest reason to buy is the ThermoBall Eco insulation, which delivers dependable warmth even if conditions get damp, paired with a fleece-lined collar that makes each step feel cushioned and comfortable.

Key Features

• Slip-in comfort: The collapsible heel and stretchy side panels let you slide the mule on and off quickly while the Oso fleece-lined collar adds soft, secure cushioning at the ankle.
• Water-resistant durability: A ripstop upper made from 100% recycled polyester with a non-PFC DWR finish sheds light moisture and snow to keep feet drier than a standard slipper.
• Reliable insulation: 100% recycled polyester ThermoBall Eco insulation holds heat in wet conditions better than uninsulated options, making these suitable for cold, mixed-weather use.
• Steady traction: A grippy rubber outsole with up to 20% recycled rubber provides confidence on slick surfaces like icy walkways or wet cabin floors.
• Sustainable construction: Multiple recycled materials reduce waste while still offering long-lasting wear for casual outdoor needs.

Who It's For

The Thermoball Traction Mule V is aimed at men who need a warm, durable slip-on for short outdoor tasks, campsite chores, or as a cozy second shoe at base camp. It works well for people who value easy on/off convenience and want insulation that performs when damp.

Shoppers who need a fully waterproof hiking shoe, structured ankle support for long walks, or a formal-looking winter shoe should look elsewhere; this mule is built as a casual insulated clog rather than a technical mountaineering boot.

Pros & Cons

Pros

Our Verdict
