Anyone happen to have these side by side to measure the top cuff?

I have a Premium Cart StaDry Bag that measures 27cm across the top cuff. This is the same as the top cuff dimension given on the Titleist site. Sadly, it doesn't fit in my car so looking for something smaller.

Looking on the Titleist site, the Cart 14 shows as having a 25.4cm top cuff and the Cart 14 StaDry shows as 20.3cm

Are they really different? They look identical, but I don't have them to measure unfortunately and struggling to get to a shop to measure. If that is the correct measurement, I'll be picking up a Cart 14 StaDry.

Thanks
