I used to buy the PI Touring Glove because they were comfortable to me and were one of the cheaper ones in the bike shop at $20. I figured a touring glove would be built to last. I went through two pairs, and each pair wore out on me in six months, which included riding them for 2-3 months with holes in the palms. I guess by calling them "touring" gloves they mean they should last one short tour and then be thrown away.

I own several Sugoi clothing items and find Sugoi to make very high quality stuff, so the next glove I tried was a pair of their $30 C9 Gel Gloves which just happened to be on sale for $22.50. I've been wearing the C9 gloves for over a year and they are holding up extremely well -- I anticipate getting 2 years total use out of them before I have to replace them. Very good investment.
