What to wear on a warm outdoor climb

Here I am doing an outdoor climb in the Spanish mountains looking very happy because I'm having a lovely little rest. Probably shouldn't have done that. Probably could have done that route without rests. Made for a cool snap though.

So Spain was SUNNY. However, being up in the mountains of Spain means you don't always feel the sun, so you will be a bit chilly if you go for just shorts and a sports bra.

What am I wearing here?
From the top down:
A trusty loaned orange helmet from Warwick University - good for climbs and also for the approaches where you feel particularly anxious.
A Nike sports bra, one of my outlet store purchases from Resorts World.
A Big Moon T-shirt, always great to represent your favourite bands when you doing abroad climbs.
Some 3/4 length leggings from Decathlon, very nice and comfortable with a great wide waistband that does a good job of holding you in BUT if you are taking a lengthy ground rest and forget to reapply suncream, it will be a bit embarrassing having pink shins looking like you haven't actually done that much climbing. Trying to pull off 'I was climbing up backwards I PROMISE' is actually quite tricky when you're this much of a novice.
The classic Boreal Jokers. I.e. My only climbing shoes. They did the trick.
