The shorts ride up and create chaff age.

I bought this very excited and spend the whole run pulling them back up. I went for large as medium boxers I find tight. I am constantly pulling the shorts down. I was looking forward to running with these.. Very disappointed

Perfect fit

Comfortable shorts, perfect to wear with running briefs from short to long distance didn't encounter any chafing
10/10 for me

Rundawear rocks.

Absolutely love the shorts and underwear.

Comfortable, but not perfect

I've been running with a size M grey pair of these for about 2 months, with a (measured) 32" waist. They're light and comfortable, and pretty much unnoticeable when running in typical conditions.

There are a few things that are a little off though:
- not sure what the tie string in the waistband is for - I've just about managed to get a knot into it, but I'm not sure what that actually achieves as it doesn't seem to make any difference to fit
- they ride up a little over the first quarter mile or so, I guess as my (Runderwear) merino boxers find their place. They don't seem to move after that, but can need manually moving back down 2 or 3 minutes into a run.
- they've got a bit of a funny shape in the genital area, in that they don't have any shape there - this means that they don't leave much to the imagination, and, in cold weather, don't give any air space between the end of your equipment and the shorts, which can result in the little chappy getting a chilly head, even through merino boxers. The shape of the shorts generally looks strange if you don't have a top covering the top half of them, due to the shapeless front.
- the size recommendation that Runderwear gives is definitely on the small side - they suggested an S for me, but I went for M, as I'm on the size guide boundary. I'm pretty sure an L would have been fine, if not better. This maybe depends on your upper leg circumference, but I definitely wouldn't want any smaller, and an L might have been adjustable in the waist using the seemingly-superfluous drawstring?!?

I would still certainly buy a second pair of these, even given the above minor faults, but they've been out of stock for months... when will they be back?!?

Thank you for your feedback this is greatly appreciated and will be passed on to team and product team. These have been a big hit so we are currently awaiting more stock which we are due to get at the beginning of the new year. Thank you for your patience and feedback.

Good, but....

Very comfortable and light, generally a pleasure to wear. The waistband, though, is effectively unworkable, and my black shorts are quickly losing their colour, fading to grey.

Thank you for your feedback, Great to hear that you find the Ultra Light shorts a pleasure to wear. These have been a great seller and a favourite for many, I will pass your feedback onto the team about the waistband!
