I have several pairs of cycling shorts....everything from shorts to bibs to knickers. Most are Pearl Izumi, one is Castelli and one is DeMarchi. They are of varying price and quality from moderate to fairly expensive. All are road oriented. So, the other day I went out to buy a long sleeve jersey and ended up at a bike shop in Mystic, CT. It's a place I've been to only once before. I found a nice LS jersey and noticed that they were having a 75% off sale on some Pearl Izumi Tri skinsuits. I'm about 15 lbs. over my ideal cycling weight but I thought "what the hell, I'm gonna' try one on." So, I tried a PI Elite suit in large and damned if it didn't feel great. Kind of minimal padding but really comfortable and actually looked pretty good. So, I went back to the rack and found a PI Pro in large. Ended up buying them both. The Elite retailed for $120 and cost me $30 and the Pro was $200 and cost me $50. Went home and went out on a ride with a pair of PI knickers I bought last year. One of the higher cost chamois and I found myself constantly adjusting and generally not as comfortable as I thought it should be. The next two days I went out wearing each of the Tri suits and found them to be really comfortable even with the thinner chamois. All of these rides were in the 20-35 mi. range. It never occurred to me that thinner might work better for me but I guess it does. And, damn I really like those Tri suits.
