rear field bag rests

I have lost two camo Holland dog gone good field bags https://www.sinclairintl.com/shootin...prod33669.aspx

I quite liked these as they were small and fairly light but spendy at $28.00US fir what they are, then there is freight...
Googling turned up a couple of options available locally (there may be more)

These are well priced and seem very light.

Another option is Norway's bag available locally

I'm sure this would be good but it's 300g

Can anyone advise on their experiences with these bags or suggest any others that may be available locally for a reasonable price?

Cheers in advance

Mine involves a school pencil case stuffed with a spare pair of socks and thin gloves.... Seems to work well

Thlr ones are good, just don't let your dog get a hold of it though.

It's just dead weight though, better off practicing with a rolled up shirt/jacket etc
