The Good: Thin, breathable, good fit.
The Bad: Durability of backhand, odd placement of palm padding.
Overall I really like these gloves! I bought them in April at Sea Otter for $10, and they have been very good to me. The back hand is very breathable and has suited well for the hot summer months and the terry cloth thumb is always a welcome feature. I own the white/green ones and they stay surprisingly clean with just a run through the wash, even after coating them in some real tacky red dirt. The grips on the finger tips have also stayed intact and don't seem to be wearing too quickly, in fact they grip so well they are rubbing the anodizing off of my Avid SD-7 brake levers!
I only have two gripes:
1. The palm padding seems to only contact the bars if you were to ride with your thumbs on top of the bars(which would just be silly), unless they were designed for crash protection, in which case they should have been a little thicker to do much good.
2. The price you pay for having a breathable back hand is a little less durability. I now have a small hole in the back of one of my gloves from a crash where my hand came in contact with a rock. They have however held up to getting snagged on blackberry vines.
I f you are just looking for a light summer glove for XC riding and don't plan on crashing too much this glove is perfect!
