Unfortunately it is no longer on sale, but this is a review based on my experience using it.
I mainly use it for shopping by bicycle, but it's not a problem because it doesn't get cold.
I wonder if it will be made of synthetic leather and how long that part will last.
I've been using it for about a year now, but since I only use it during the winter, it looks like it'll be usable for the time being.

It has a three-dimensional shape, so it has a good fit. I gave it a minus 1 because I can't use my smartphone while wearing it, so I have to take it off. It's waterproof, so you can remove snow from your car's windshield without getting wet. Since the temperature has not yet reached freezing point, I will not be able to evaluate it yet. I don't know if they can be used as motorcycle gloves. It's comfortable in the car, and snow removal seems to be no problem.

Men's Endeavour Gloves

First of all, if the speed exceeds 80 in the morning at around 0 degrees Celsius, it will have no effect at all and your fingertips will hurt, so it is suitable for city riding.
And the deciding factor was that it said (completely blocks rain and snow from the outside), but I was building a kamakura out of powder snow while camping in Hakuba during the year-end and New Year holidays, and I thought it was kind of cold. The snow seeped into it and hurt my fingers, rendering it unusable within a few minutes.
I changed them to ski gloves and they worked better.
After purchasing the Endeavor jacket at Makuake, I bought it to match with gloves and a hat, but I'm very disappointed.

I use it on my bike when commuting to work in temperatures of minus 1 degree.
I definitely feel the effect of the insulation.
It's not warm, but it's a strange feeling that doesn't make you feel cold.
Of course, if you put in a pocket warmer or something, it will keep you warm and be more comfortable.
However, even M is too big for my hands.
The gloves are large and leave room for your fingers, making them unsuitable for riding.
Also, the part that covers the cuffs is too small to fit over the sleeves.
I was a little disappointed that they didn't use Velcro or a drawstring.

Overall
I am very satisfied with these gloves as they keep me warm.
Of course, I think there is a lot of room for improvement, but I look forward to future improvements.
