Hi Ummb..., I've done the Ragbrai, it does get hot! I bought these bibs here at TE last summer for my ride from Oregon to Jackson Hole. It was super-hot. These bibs are like airconditioned shorts - super comfortable chamois, nice fitting, very high quality and no pressure on your tummy. They are well worth a try, I know, they're black and white (I call them my penguin shorts) (or kind of tuxedo looking) If they still had my size, I would buy another pair, they are that nice for hot riding conditions! Once you try the high-end Louis Garneau shorts, you're kind of spoiled for anything else! http://www.teamestrogen.com/products.asp?pID=18029. Have fun at Ragbrai! Tokie
