Fox Racing Flexair Pro Pants - Black - 36
When you're seeking, and pushing beyond your ride limits, progressing and testing skills on ever-more demanding trails, the Flexair Pro Pants offer the very best balance of flexibility and low weight without making a sacrifice to durability. For those times you need to react quickly to trail and terrain, it's the TruMotion fabrics that allow you to move with optimal speed and mobility. This flexible fabric is also complemented by the performance fit. This sees a slim leg that tapers down towards the ankle, minimising both speed-sapping flapping and preventing chain catch and snags on trailside vegetation. When it comes to extra durability, it's the Dyneema knee and leg panels that give it a big boost. Incredibly light and yet incredibly tough, this will fend off attacks from overgrown trails and add slide protection in the event you get caught up in a crash. Trail riding comfort is enhanced via the use of TruDri technology, mesh panels to the back of the knees and strategically positioned laser-cut perforations. TruDri is quick to wick away sweat before you feel any discomfort while the perforations to both the front and back of the pants allow for extra airflow, keeping you cooler on a hot day. You'll also be pleased to find the pants have a Durable Water Repellent finish. This will shed dirt and moisture when you encounter damp trails. A secure and easy to adjust fit comes courtesy of the proven race-ratchet closure. And you can even adjust it on the fly for optimal fit. No annoyance from slipping pants to be found here.

Fox have absolutely nailed it with these pants. Material, fit, finish is excellent with an unbelievable feel and stretch- it's tough to put into words how good these are. Innovative step forward in MTB pants. Bravo

These are the first MTB cycling trousers I've purchased, previously Ive been a roady so moving away from lycra was going to be different. The fit is superb and quality ia almost 5 stars, however I did find the finishing on the inside of the leg zips was poor and rough which on my first ride rubbed on the back of both legs, this has been sorted by putting some tape over them. Perhaps not ideal for use in Jan / Feb months but impressed and no regrets in my purchase

Excellent fit, materials and style. Rugged material at the front knee. Knee pads easily fit under, I like the lower leg zipper, making it easier to put on/take off.

Pant fits on the slim side. It’s stretchy, so the ride uphill goes smoothly. There is no strain through the leg. The one area where this product could improve is adding dyneema to the back of the pant mainly for flat pedal riders. When riding sometimes the foot slips, and the pedal screws dig into the back of the pant, creating holes and rips.
These pants have a slim fit and are super lightweight. The knees have a reinforced texture and the bottom of the legs have zippered openings to keep them tight around your ankles. My only complaint is the sizing is a bit small and the waist does not have any stretch. I normally wear a size 30 and these barely fit with the waist adjustment so I suggest going up one from your normal size.
The pants is very breathable in hot weather. The stitching of threads semi durable for bike park. The knee patch is made of tear resistant fabric. The waist fabric is very smooth that cause the pants to drop downward. I have to add rubber waist band to pants to prevent it from sagging down. That is all
I like the tapered cut, not baggy yet not too tight even with my knee pads on. It is very comfortable and has an added layer for abrasion protection from branches or tall grass along the trails. I got it on sale so it's an added bonus.
Note that I am using these on my offroad motorcycle. I find dirtbike specific pants to be too wide and pricey for what you get.These are tight fitting - I'm a 32" waist and had to go up to a 36" when wearing padded protection shorts. So I would size up.Very light weight, breathe well and look good.
Form fitting, but stretchy, lightweight, and breathable. Almost as cool as shorts on a hot day and way more stylish. Dyneema panels on the knees help them hold up after a crash (I've tested them). Would love to see these offered in more colors, especially bright red!
Awesome pant, light weight, cool running, look great but beware the crotch is cut really short and much too close to the body so there really is not any room there at all. I guess that's fine if you like showcasing your package goods but I'm not so keen on that. Also, these fit tight so probably size up is in order. Im 5'10 175lbs and usually ride 32 - 34 waist. I had to order 36 waist just to fit the crotch (somewhat better) and will have my wife take in the waist to make that a 34 with her sweet sewing skills so the waist of the larger pant size will fit me.
