Our burliest pant, the Fat Jack moves from the bike maintenance shed to snowy trail rips on the fat bike with ease. These pants combine the toughness of workwear with the technical performance you need for cold weather rides. Whether you’re running errands on the cargo e-bike or tearing up singletrack, the Fat Jack has you covered with its stretch, water-resistant fabric and reinforced canvas leg patches.

These pants aren’t just tough—they’re smart, too. Side leg pockets provide secure storage, while upper leg vents help regulate temperature when things heat up. Reflective accents offer added safety for night rides, ensuring you’re visible even after the sun goes down.

Key Features:

  • Stretch, Water-Resistant Double-Weave Fabric – Flexible and protective for all conditions 
  • Durable Canvas Leg Patches – Extra reinforcement where you need it most Ventilated
  • Side Leg Pockets – Secure storage or open vents for airflow during hard efforts
  • Reflective Accents – Boost visibility in low-light conditions for added safety
  • Versatile Design – Performs equally well on snow, dirt, or pavement

Why You’ll Love It: The Fat Jack pants are designed to handle whatever you throw at them, from winter snow rides to spring dirt trails. The durable fabric moves with you while providing protection against the elements, making these pants as versatile as they are tough. With thoughtful features like ventilated pockets and reflective accents, you get all the performance you need in a stylish, hard-wearing pant.
