Bought these gloves as my coldest weather gear. I like them a lot but they are a bit bulky and make finding my shifters a bit tougher. I wear them on rides getting down into the teens and they work, but I will often add in some hand warmers to assist. I bought a size large though I usually wear a medium so i could slip on some liners if needed. Material and construction are very good and are in keeping with Pearl Izumi's quality.
I have many gloves, but nothing that would keep my hands warm between 25-35 degrees. Worn alone, these gloves are just fantastic! If the temperature's lower and into the teens, I add a think liner glove underneath and have no problems whatsoever. For this reason however I would suggest ordering one size up to allow a thin liner.
I had the same pair of winter gloves for the last 10 years and they served me well, but they finally became unusable this winter. Since it had been so long since I had purchased any winter gloves, I was a bit uncertain which to get. I looked at several different types by different manufacturers. Riding all winter in Minnesota you need to have a glove that will not only keep your hands warm, but also dry and keep out the brutal winds that can be present in the winters here. I have to say that these gloves did not disappoint in any of the areas. My hands were warm from the start, which can be an issue when bitter wind chills are the order of the day. Also the second ride I had them I was out for over 2 hours with wind chills in the single digits and there was not even a hint of my hands or fingers being cold. These are by far the best winter gloves I have ever owned and I would highly recommend them to anyone considering riding in the winter.
These gloves work well and keep your hands warm until they get soaked through. They have good water resistance, but I got caught in an unexpected heavy rain hail storm. After about 30 minutes they soaked through then I might as well have thrown then away. But up till that point they ketp my hands warm.
This glove fits snugly but well, and it's precurved to follow the natural contourcurvature of your hand. I use it down to about 32deg F. Below that and I opt for PI's lobster gloves.
No problems operating Shimano STI shifters with these gloves!
These gloves are great. They work well for far more then just cycling. They are very warm, and fit me perfectly. I don't have to worry about my hands going numb when it is really cold out. I find I need to break these out for rides once the temperature gets down to about 20. Up until then I use a much thinner and lighter glove.
I really struggle with cold fingers during the winter months, having been known to wear cycling glove liners covered by disposable food service polyethylene gloves covered by a Windstopper or half-lobster outer shell gloves in the low 40s. The P.R.O. AmFib Gloves take me down to the same temperatures with just the one layer. The gloves work well and amazingly dont hinder Di2 shifting. My only complaint is that the liner material for the small finger can tend to bunch up, making entry somewhat difficult. Holding that glove finger while working your actual finger around usually allows it to slip on OK.
Relative to another reviewer who suggested sizing up to allow for potential glove liners in really cold weather, I did try on a pair one size up in a local store (only pair they had in stock). The XL really swallowed my hands, and Im concerned if the dexterity needed in the fingertips for Di2 shifting would be there.
