I bought these for their windproofness. I've worn them a couple of times and they certainly protect from the wind. They're not insulated on the topside (palm side has a little insulation) and that means I had to wear Decathlon's silk liner gloves with them to keep my hands warm as well as wind-protected. Very happy with the layering capability though.
Only downside is the touchscreen capability doesn't seem to work for me. It works for my other half though so it's either that my hands aren't big enough to fill the fingers and provide good enough contact or there's some other factor (e.g. hand sweatiness) that impacts the performance of the touchscreen capability.
Typical Decathlon quality. Light but warm with pad on finger to enable smart phone use. Fit is snug.
Nice gloves but didn't really keep my hands warm.
Good fit and ideal for a chilly day
Poor touch screen tips and nor ideal for cold days
