sigberto wrote a review of Craft Siberian Gloves on January 4, 2012
I first ordered a pair of the Craft Siberia that came with some stitching undone on the side of a finger. I exchanged them for the same pair with no problem. I have been riding with that pair during all of my coldest rides for two winters now. No serious problems.
The medium-thickness insulation in the glove is warm enough for freezing temperatures, although I frequently bring thin wool or poly-pro glove liners to wear underneath these gloves once my hands are already damp and sweaty. That helps keep my hands warm for the second half of a long ride. (I rarely start rides that way unless the temperatures are under freezing.) Depending on your tolerance, these gloves are too warm for 45-50 degrees or nicer temps! The wind-proofing does what it says.
The leather palm is very soft (and works on my iPhone if I use a spot or finger without grippy dots), but has no real padding like a cycling glove. That takes some getting used to. It is arguably the biggest weakness of these gloves to me. The only other weakness is that the Velcro has frayed much over the past year and I sometimes have to re-stick it. One of the strengths, however, is that the thumb has great protection on the inside Ive used other gloves that fray after time from friction with shifter hoods. The leather on the inside of these protects them well.
The little dot grippers on the hand will wear down wherever your grip the bars tightest, or put the most weight on your hands. For me, thats primarily on the ball of the hand where the ulnar nerve is usually protected by most cycling gloves, and parts of the finger tips. Thats fine it doesnt really need them anyway.
Although these gloves have endured a few grand tours worth of wind, sweat, snot, and winter training miles, and I hope theyll last through at least this winter, I personally would consider a glove with more palm padding next time. If that is not essential to you, pick em up. Craft makes a nice product overall.
