Ultralight poncho

I like using a poncho for rain as I just like it better than having a pack cover and rain jacket.

So I'm looking for a light but good poncho which is big enough for a 1.90m man to stay reasonable dry, while having the backpack under the poncho as well.

I currently have a 350g one that in emergency doubles as a tarp.

I have sadly not found one that is lighter and smaller.

The tarp function is optional as I luckily did not need to use it yet.( I carry a tent)

Additional I'm in the EU. So most of the high tech dynema companies are in the US and hard to get here.

Any recommendations?
