I just ordered a some spares for the original Kubi gloves. While I find the original gloves to fit well (the 10.5 XXL) I threw in a few extras when I placed an order for some spares. Got these
Condor Chemical Resistant Rubber Latex Gloves, 29 mil, Size 11, Orange 48UP35 | Zoro.com and the same in 10. The orange 10 fit very close to the original 10.5. The 11s I listed are noticeably larger. Too large for me, but at $1.80 a pair I will find some use for them. Even if it is using them as a disposable oil change gloves for the truck.
I literally opened the box today so I can't say how they work in the water, but I expect them to work just fine. Already fitted one to one of the rings. Next dive is going to be an equipment fine tune/shakedown at the end of the year. Planning on running one orange and one black, see if there is any noticeable differences between the two.
