As you can see I bought the Wee Space version of the Pace Rival crops. Currently, these are only in US stores. This material is regular luxtreme and like most Wee Space luxtremes tends to feel lighter than regular luxtreme and a lot lighter than full on luxtreme. The Wee Space is opaque and gives good camouflage to leg imperfections. It also buttery soft but a bit less compressive than other luxtremes. I like to use my Wee Space run crops in the summer because of the lighter material. The Pace Rivals were decently cool, given how long they are. The circle mesh on the back of the leg gives some nice cooling. I did find myself becoming a little warmer once I turned inland and lost the ocean breeze but if you like to run in crops these are a good choice for warmer weather running. All in all, the Pace Rivals are a very nice successor to the Inspires though I do find the styling at the leg opening a bit generic, unlike the Inspire's easily identifiable arc.
PS - On a related note, the Mesh What the Sport Tees have become my favorite run top - great wicking, breathability, and they don't ride up. You can wear a Ta Ta Tamer without it showing. The lighter colors are a bit see-through, though. I've already bought all three colors and would love to get more.
