Hello. Most riders who are truly in between sizes tend to go with the larger size to start, just so that they're not wearing something too small/restrictive. But we're all proportioned a bit differently, of course.
Since these are bibs that extend up the torso, it would be important to take his body type into consideration here so if he is on the slighter side of the spectrum then the smaller (3XL) size may be more appropriate but if he is like us and has a bit of a beer belly, etc. then perhaps the 4XL would be best to start.
Please let us know if you have any questions at all and we'd be more than happy to help: 1-800-783-8326 or cyclewear@aerotechdesigns.com.
Thanks!
