Nathan O.wrote a review of Craft Siberian Split Finger Glove on March 12, 2015
Familiarity: I've used it once or twice and have initial impressions
I rode these once and was hoping that these would be my new winter freezing temp gloves. However there are a few 'notes' that i'd like to bring to light on these. They do have some fleece inside and are quite warm while wearing them around the house or whatever, but the issue with these and other gloves too, is that the outer shell isn't wind proof* (different than resistant). This for gloves is the big issue for me if you are looking to use these while riding under 32F. Letting in air is the heat zapping part. Standing around in these gloves not moving, your hands will be warm no doubt.
Secondly i the idea of lobsters were awesome, until i started to ride with them. My hands are kinda small but when i shift (on sram shifters) I use my middle finger to shifter the RD, not my index finger. If you can imagine this in your head, it makes it weird and not ideal when your index and middle fingers are essentially 'tied' together because of the lobster effect. Maybe if the glove was 1/3 split and not 2/2 split, but still.... not ideal for me personally.
these two factors made me return them. I think they are warmer standing still than my Assos Fugu gloves, but while riding , i do not think the craft are noticeably warmer nor 'better performing'.
