On top of your biking gloves?
Did someone try it to make it windproof/waterproof? Thinking on some cheap solution for the cold temps in the early morning

Sweat is the enemy of warmth imo. If your trying to minimize air flow I'd suggest bar mitts. Those latex gloves will just cause moisture to accumulate quickly, giving heat a rapid path away from your hands. Layering gloves that breathe is the best solution.

I can barely get those things on w bare hands, never mind over a glove

this used to be my inexpensive go-to cold-weather solution. the trick is finding another pair of gloves big enough to fit over your regular gloves

The Crab Trap Handlers off the Alaska Coast Use heavy neoprene gloves, 2 pair ,
seawater there is cold.

For just cold, not wet, get pogies ..

gotta let em breathe

At the right temperature/wind doesn't sound like a bad idea. You have to experiment with those ratios and let us know the results.

Is Vapor barrier, Perspiration is a way to lose excess heat, by evaporation,

Blocking that perspiration with a vapor barrier stops the cooling evaporation
and also blocks the insulation from holding the wet condensed perspiration vapor,
so when really cold your insulating layer retains it's loft.

an aluminized vapor barrier also reflects heat back in... your space blanket function..

For once I agree with fietsbob. Using latex gloves or in some cases bread bags for feet is an old winter hiking trick, for very low temps when it's so cold outside that the dew point is somewhere in your insulating layer. Meaning the moisture from your body doesn't make it all the way to the outside to evaporate and condenses too early WITHIN your layers, giving you a damp layer that facilitates heat loss. This kind of use is a little different from what the OP is suggesting though. Latex gloves would block wind but they would probably look odd on the outside, put them on first.

There's an explanation of VBL and a lengthy discussion from Andrew Skurka himself here:

Last week I actually saw a cyclist with ziplock bags sticking out of his shoes. It wasn't even in the 30s that morning - low 40s.

Sweat is the enemy. I have a pair of Specialized cold weather gloves from around 2008. They are a two layer system with the outer glove water and wind proof. Can only use the inner glove because my hands freeze with the outer glove on due to sweat buildup. Bar Mitts are a superior solution. You can easily make them yourself out of any waterproof material, too.

I found it was much warmer to wear the disposable gloves underneath your gloves. I learned about it a few years ago and since I have "sweaty hands", it helps me keep them much warmer. However, they get very wet inside the disposable glove after an hour........

I got ammex nitrile L size ones from a->z to try out.
On low 40F early morning ride, after some 20 min, it gets sweaty, then I just remove on my traffic stop and move on.
On last Sunday, I was riding under some rain, so had it on top of my bike gloves - after rain passed I just remove them and put into side of my socks.
Then when cleaning and lubing the bike I just used the same gloves and didn't get my hands dirty

So, 100 gloves for below 10 bucks seems a great cheap thing to have around and they are strong enough I can use multiple times without disposing after each use.

I've worn them under other gloves a few times for cool weather downpour conditions.

Something with a waterproof and breathable membrane (like Gore Tex) is likely a better long term solution. Not as cheap initially, but worth it if you're doing lots of cool/cold weather riding!
