The Good: thin palm, color options
The Bad: nothing really
Some riders go glove-less but I like gloves on my hands (thin palm only please). There are countless times I've been thankful I've worn them during crashes, etc. and the Fox sidewinder are the best I've worn over the past 9 years or so of mtb. I wear them on everything from local trails to the bike park.
I have to say that I wish there was a softer fabric on the backside which comes in handy when wiping sweat from your face, but the tough fabric found on the sidewinder holds up to abuse better.
The only thing that threw me off at first was that the glove comes up a bit high on the wrist but that doesn't interfere with anything and may just give a little extra support and protection for the wrist.
