I can assure you that at 100 km / h, I saw no difference between the two at the cold and wind protection.
On a long drive by these temperatures, it will add a sub silk glove, but it is like my motorcycle gloves, so equality.
Anyway, I do not recommend to make the bike because I'm not sure they are pretty abrasion resistant if dropped.
A book for which they were designed: winter sports.
The presence of a wrist strap to tighten securely holds the glove when falling (skiing, sledding ...).
They climb high enough on the forearm to coat the sleeve of the coat or snowsuit.
M size is good (it's the one I usually take), finishing (cutting, stitching ..) is is excellent.
I have tested you in the rain but a previous review demonstrates their seal.
So a product without faults.
If you do not have your gloves for this winter, you can go.
I know this brand recently (I also have a jacket) they have the area to make quality products! To discover.
