Really too individual to tell. Some need the padding of a DeSoto 400 mile short and others just a thin tri short lining. Also depends on race distance for sure.
The Sugoi tri shorts are pretty “in between” as well a couple of the newer Oomph models (I’ve never tried them). You will like find the Zoots too thin and the Pearls too bulky IMO. Definitely order from a place with a return policy if you have no local shop in your area.
The “more expensive” shorts in their line carry a lil more padding. 1st Tri short I can wear for 112 miles COMFORTABLY. But, DO NOT wash in the washing machine.
You won’t be disappointed…unless you like flashy colors.
