Running

I have a waterproof jacket I got given at a race, it's ok for light showers but it's a nightmare to get off when it's wet. I have to make sure my watch is out of the sleeve as otherwise it gets waterlogged. It's white and so gets filthy easily too. Maybe you get what you pay for? (LOL just kidding, go to decathlon)

If you’re in hills or mountains or out for hours upon hours then a quality waterproof is sensible (more so if you have to stop or slow down)

For urban / park stuff for up to a couple of hours then I just use a cheap decathlon gilet if it’s raining - the wind proof one that breaths rather than the actual waterproof. It’s enough to act as a layer even when it soaks through.

Fwiw I use:

Remote = Montane Minimus over merino layer(s) depending on time of year.

Local = Montane featherlite (wind jacket) over Merino.

Last night the wind jacket came off as I warmed up and was carried scrunched up in my hand as it's tiny. Although wet the merino layer (long sleeve) kept me warm. In winter I'd do same with extra mesh layer under the merino.

If it's a shorter local run from & to home I'd likely not bother with waterproof.

Never bothered with a waterproof for running...just wear a cap to keep rain off the glasses

some decathlon joints looked ok, I recall their "trail" running one packed up into a little pouch with a handle that you could hold whilst running.

OMM Kamleika. Ticks all the boxes for me. Worn it on many long wet days out running in the hills.
