Our crew often rides hard and we are here for you when things go awry. If you crash and trash your Kitsbow, get in touch with us.

If it can be repaired, we'll do that for a reasonable charge. If it can't be repaired (if you were really ripping it), we'll figure out a way to get you back on your bike wearing Kitsbow anyway. Just get in touch. The same policy applies to typical wear and tear: we'll repair it for a reasonable charge (if it can be repaired) or get you back into Kitsbow some other way if it cannot be repaired.

mesh briefs

They fit great; worked well on a bike packing overnighter. No chafing.

Goodbye padded shorts!

I’ve been riding without padded shorts now for 6months thanks to these boxers for all but the longest rides (4hr+) and it’s been amazing! So much more comfortable on and off the bike. It’s always preferable to get out of the riding gear completely after a ride but if you can’t and you’re sporting these it’s no problem as they do a great job of getting the moisture away from you. They might seem expensive if you think of them as just boxers but if you compare them to padded liners they are CHEAP!

Yes to these

As someone who doesn’t ride in bibs or padded shorts all that often, the entire line of Kitsbow boxers are among my favorite. The overall construction and thoughtful placement of seams on their boxers are more intentional and innovative than any others I have used. With the mesh boxers the added breathability is a major bonus. I highly recommend these.

Inseam too short (for me)

These feel amazing and I was excited to try them. Unfortunately, the fit is not a match for me. The sleeves rise up my legs and bunch up nearer to the crease of my hips/pelvis. If you have ever experienced this with a boxer/brief, you recognize that it is awful. If you have never experienced this, you are more fortunate than me. My height is at the tail of the distribution, (195cm), so this product may be a wonderful option for more common heights.

Ditch the chamois

The early days of riding my mountain bike had nothing to do with a chamois. I've been incredibly stoked to have a comfortable moisture free layer to wear under my baggies. These boxers have revolutionized the way I look at my underwear drawer. I am now disappointed when these, or the Kitsbow Trail Boxer aren't there. Get a pair of these or the trail boxers. Or both.
