looking for a good pair of bike shorts but do not know what size to buy.
have never bought bike shorts before.
57 year male with a 34-36 inch waste.
@joe0802 Thanks for reaching out!
Bike shorts tend to run fairly true to size, so based on the sizing guides for each brand we would recommend going with a size large, which fits a 35"-38" waist, depending on the brand. Take a look at the Pearl iZUMi Escape Quest Bike shorts or the REI Co-op Junction Bike Shorts. Also, if you're looking for bike shorts that have an outer short and inner chamois liner with them, check out the REI Co-op Link Double Bike shorts.
Lastly, this Expert Advice article, What to Wear on a Bike Ride, has some good information about bike shorts that you may find useful.
Hope this helps!
Should be just like sizing regular pants, but beyond that it's just a matter of trying them on to see how each brand is cut differently. As you try some on, just keep in mind:
