The pics with your hand and glove, lying on the gridboard, is very helpful.
Looks like your suede gloves are 10" long, 5" wide at the cuff, a bit less in the middle. The longest finger is a bit under 3.5".
Found another outfit that has numerous offerings in XXL, XXXL, and XXXXL. AND, they're having a big discount going on...

...The carhartt gloves are certainly wide enough but the finger length looks a little short to me ...maybe 3.5 " ?
They're just a bit over 3.5", maybe 3.7".
I like the deerskin gloves although they may be a little inflexible for motorcycle use ?
Actually, deerskin and goatskin is more supple and stretchable than cowhide, deerskin being one of the more preferred for motorcycling. However, cowhides can be stretched/shrunk to fit better. Some info and videos on "fitting leather gloves". There's other hides out there, like sheepskin, kangaroo, ...etc, but I have no experience with those.
The schmit heavy duty look very interesting as they are the only work glove I've seen in black , I like the palm reinforcement too. presumably they are suede ? its difficult to make out .
Yeah, those look nice, black suede with tanned leather reinforcements, but that's the largest size, and much too small.
I also like the suede gloves a lot they are probably the most flexible I would image.
No, rather stiff compared to the better skins. They're the budget $10 gloves.
I do have some suede gloves which are really difficult to get on and off but are nice and supple and warm.
the problem as always is that even though they are the largest size they produce the fingers are only 3.5" long . Consequently the gloves always feel like they are cramping my finger tips just like wearing a pair of tight shoes cramp you toes.
The West Chester deerskins, above, $20, in XXL, have 4" finger length.
I think the answer is going to be with a pair of suede gloves preferably dark in colour and an xxl size if such a beast exists...
