Netting will rub your dick raw!

I exclusively run in 2-in-1 shorts that have built in spandex like liners. Some are more 'compression' than others. Most are just supportive, not compression. I like the Nike 2in1s and they last a LOT of miles. I've tried a few cheap amazon brands and not liked them nearly as much. The liners are never as supportive.

I only buy unlined shorts, and wear my own boxer briefs. The shorts last way longer than the liner does, in my experience, so it's easier to just separate the two functions into two separate items. It's the Unix philosophy.

Always underwear. Aside from the netting being coarse on my delicate skin down there other people don't want to see my cock swinging around so blatantly in my shorts. I've seen it on other people and it isn't a good look. Also swinging free like that is super uncomfortable for me, I want my shit locked down and not slamming into my legs!

No, it's uncomfortable to combine the two.

Race shorts with netting no undies. Regular shorts I wear compression shorts.

I run in leggings mostly, and underwear feels wrong underneath that

It’s a personal preference. For me, I only buy shorts without liners and wear my own from Saxx. I tried a bunch of different built in options about 15 years ago and ran into uncomfortable compression or chaffing issues.

I Kramer it up baby, I'm out there and I'm loving every minute of it!

Shorts and underwear. I don't have any fancy netting shorts

Does anyone have links to some good shots?

My Patagonia running shorts have built in firm boxers. So good.
