Yep, failing to do round the world on this pony. I seem to remember falling off doing round the world most weeks. Something about 1970s pony saddles and slippery jodhs.
I sound like a broken record, but the Uvex Exxential has a removable liner, and is light, well vented, adjustable and available in colours other than black. Get one from a UK seller and it will be kitemarked & VG1 so street legal for most but not all activities.
Ok, so, different dogs are built differently, but this one is 17kg at 7 years old. Something corgi-sized that is her weight plus 3kg must be in a terrible state. Poor dog.
For those who haven't seen it before, this is an interesting, measured and helpful article which explains how all of us can be blind to other road users, and what to do about it.

Ebay and / or FB Marketplace is your friend, if second hand clothes don't give you the heeby jeebies. For the cost of a new pair at RRP you can buy a few, keep the one(s) you like and sell on the ones you don't. If you buy from FB, only ever pay PayPal Goods & Services or cash on collection.
