Product Information

Full details

The Fox Flexair Race MTB Pants are designed for elite mountain bikers who prioritize breathability, mobility, and a lightweight feel during intense climbs and technical descents. These pants excel by offering a highly tailored, non-restrictive fit that integrates moisture-wicking technology and all-way stretch fabrics for maximum comfort on the trail, though they may feel slightly too thin for riders who frequently navigate dense, thorny brush.

FAQs

Are these pants waterproof?

No, they are water-resistant. The DWR coating will shed light moisture and trail spray, but they are not fully waterproof or seam-sealed.

Can I wear knee pads underneath these?

Yes, the pants are designed with a tapered but flexible fit that accommodates most slim-profile mountain bike knee guards.

How do I ensure I get the right size?

The Flexair pants feature a race-fit. Refer to the standard waist sizing guide, and remember that the ratchet system offers significant adjustment room at the waist.

Are the pockets large enough for a smartphone?

The bonded zip pockets are sized to hold essentials like keys, energy gels, or a small multi-tool. A large modern smartphone may fit, but it might feel bulky due to the close-fit nature of the pants.

What is the primary difference between these and casual MTB shorts?

These pants provide full leg coverage for protection against foliage and trail debris while offering superior breathability and a more aerodynamic profile compared to loose shorts.

Troubleshooting

Ratchet buckle becomes stiff or difficult to operate

Clean the ratchet mechanism with water to remove grit or dried mud, then apply a tiny drop of silicone-based lubricant if necessary.

DWR coating seems to stop beading water

Reactivate the DWR treatment by tumble drying the pants on a low heat setting for 10-15 minutes or using a spray-on DWR replenishment product.

Pros and Cons

Pros

  • Extremely lightweight and breathable construction
  • Excellent range of motion due to TruMotion fabric
  • Secure and easily adjustable race-ratchet waist
  • Effectively sheds dirt and light trail moisture
  • Minimalist design avoids getting caught in the bike

Cons

  • Material is thin, offering limited protection against heavy abrasions
  • Not intended for cold weather without thermal base layers
  • Higher price point reflecting premium race-oriented materials

Setup, Compatibility & Care

To ensure the best fit, utilize the race-ratchet system to dial in the waist circumference before hitting the trail. These pants are designed to work well with most slim-profile knee pads; however, if you wear bulkier, heavy-duty knee guards, you may want to test the fit to ensure there is no binding behind the knee.

For care, machine wash the pants in cold water using a mild detergent. To maintain the DWR coating effectiveness, avoid using fabric softeners, as they can coat the fibers and prevent the water-repellent properties from working. Always hang dry these pants to preserve the elasticity of the synthetic fibers and the integrity of the bonded pockets.
