Product Information

Full details

The Fox Flexair Pro Mountain Bike Pants are designed for elite mountain bikers seeking a lightweight, high-performance solution for aggressive trail riding. These pants excel by combining durable Dyneema impact protection with an all-way stretch fit that keeps riders agile and dry, though they are specifically engineered for performance over casual lounging, meaning they have a more technical fit that some may find restrictive off the bike.

FAQs

Are these pants waterproof?

They feature a DWR (Durable Water Repellent) coating to shed light moisture and trail spray, but they are not fully waterproof.

Can I wear knee pads underneath them?

Yes, the Flexair Pro pants are designed with enough room to accommodate most standard mountain bike knee pads.

How should I wash these pants?

Machine wash cold on a delicate cycle. Do not use bleach or fabric softener, and hang them to dry away from direct heat.

What is the inseam length?

The inseam for these pants is 31 inches.

Do these pants have pockets?

These pants focus on minimalism to reduce weight and snagging, so they feature minimal storage options compared to casual cargo pants.

Troubleshooting

Ratchet closure not holding securely

Check for debris or dirt in the ratchet teeth; clean with a soft brush and water to ensure a firm lock.

Pants feeling stiff after washing

Ensure no fabric softener was used, as it can coat the fibers. Run a rinse cycle to remove residue.

Water is soaking in instead of beading

The DWR coating has likely worn off; reapply a technical DWR spray to the outer shell.

  • Superior ventilation for hot weather riding

Setup, Compatibility & Care

To ensure the longevity of your Flexair Pro pants, follow these care guidelines:

  1. Fitting: Adjust the race-ratchet closure while in a riding position to ensure the waistband sits comfortably across the hips.
  2. Compatibility: The 31-inch inseam is designed to work well with most knee pads; we recommend testing them with your specific guards to ensure no binding occurs.
  3. Cleaning: Wash in cold water on a delicate cycle to protect the DWR coating. Avoid harsh detergents or bleach.
  4. Drying: Air dry only. High heat from a tumble dryer can damage the stretch properties and the integrity of the Dyneema panels.
  5. DWR Maintenance: If the water-shedding performance decreases, reapply a standard outdoor DWR spray treatment after washing.
