Nice gloves, but not too warm
Let me begin this review by stating that I seem to have poor blood circulation compared to most people, and thus prone to getting cold hands. I've worn these gloves a handful of times (no pun intended) now in a variety of conditions: from completely dry to a downpour, and from 5°C up to 25°C. Pros: First of all, they have an excellent feel to them -- literally a second skin. They are also formed into a partially closed-hand position, so when you wear them, neutral hand position is already beginning to clasp the handlebar -- a nice touch. Additionally, the silicone grip on the palm and fingers is indeed very grippy. Again, absolutely no problems holding onto the handlebar even in the rain. Cons: The main disappointment I have with these gloves is that I cannot figure out when to use them. I found that in rain when the temperature is below about 15°C, the gloves do not provide sufficient warmth -- you end up with wet, cold, numb hands. These gloves are not waterproof. I don't know why the word 'waterproof' is even in the description. Rather, they absorb a small portion of the rain and hold that against your skin in order to capture heat -- the same as with a wetsuit. When riding in the dry and the temperature is above 15°C, you will probably find your hands sweating a fair amount -- and these gloves are not at all breathable. Thus you end up with hot, sweaty, uncomfortable hands. So when exactly should one use these gloves? In the rain when the temperature is over 15°C? You probably don't need any special gloves when it is this warm out unless there is a strong wind blowing. In the dry when the temperature is under 15°C? Again, I already have other non-rain specific gloves for this purpose. And for those of you thinking you will bring these along in your jersey and just pop them on when the conditions are right: be warned, these gloves are not easy to take on or off. Every try to take on/off a tight fitting rubber glove? These are like that. While you could probably do it while cycling, I wouldn't really recommended it as you run some risk of distracting or destabilizing yourself. Of course, you could probably stop and do this, but I'm generally hoping my gear helps to keep me going rather than requiring me to stop. Lastly, note that these gloves are very slow to dry (again, going back to the fact that they are not at all breathable). They are machine washable and seem to be holding up fine to the powdered detergents I use. But after that wash (or after getting caught in a good amount of rain), they take about 36 hours to fully dry back out. It's a similar story with drying sweat out after a ride. Conclusion (aka tl;dr): A nicely designed set of gloves with a good feel and aesthetic; but their lack of versatility and breathability makes me question their usefulness.
