Triathlon Gear...underwear

Nothing gets between a triathlete and their shorts, except maybe a little Body Glide or Chamois Butter.

Seriously, nothing.  It seems weird but you will get used to it very quickly.

Female or male, an extra layer under the tri/cycling shorts is not a good idea.  It will get really uncomfortable if the layers rub together and start to bunch up.

I wouldn't even think of putting anything else on with my tri shorts!

In the winter I wear sport boxer-briefs under my sweat pants or sometimes under compression capri pants.

But this is to keep my man parts warm.

Though I know my wife does the same.

Guess rule is:

Workout gear longer than knee->underwear

Workout gear shorter than knee -> comando

I thought the whole point of triathlon shorts was so that you didn't have to wear a swimsuit. I bought a tri suit so that I wouldn't have to solve the problem of pulling on shorts over my swim suit. It seemed like it would be too much fabric in the crotchular area. 

But I always go commando in my running shorts and bike shorts now, so it just seems right. Once I discovered the joys of lined running shorts, I never went back to underwear. I also live in the rainforest (exaggeration) and prefer the least amount of clothes on as possible to manage my UHL.
