Sorry, serious question. What are the major differences between $200 bike shorts and first cheapest choice of $20 ones from Amazon?

I find the pads are more comfortable, the bibs fit better, and they last longer.

I agree with this. The DeSoto 400 mile bibs are great for me on the road bike, but so are Castelli bibs and Pactimo bibs. On the tri bike, these are all way too bulky and cause a lot of chafing for me. The best shorts I've come across so far for the tri bike are Castelli Free Tri shorts.

For me bib shorts are so much more comfortable. A bit more inconvenient for bathroom breaks but other than that better in every way.

My current favourites are either rapha brevet or rapha pro team. Slightly different fit, compression and pad placement between the two but comfort wise they are my go to shorts for long rides.

DeSoto 400mi bibs.

"Two pairs of bibs got holes in the crotch after 18/24 months. The Tribibs ripped in the thigh pulling them up. "

Did you contact Emilio? I have had few problems with my dozens of DeSoto products, but when I have he/they have immediately made it right.

I have couple pairs of Emilio’s 400 mi bibs. I just prefer the riviera shorts with 7mm pad for any distance ride. Easier access, too.

YMMV

It took me a lomg time to realize that I should wear a different short on a road bike vs tri bike
On a road bike I love De Soto 400 miles short but too much material for a tri bike
I wear Huub short or Zerod Long distance short for triathlon!
It seems that fro triathlon position less padding is much better, at least for me.
