So, after running the London marathon in very warm conditions, I decided to invest in some headwear to give myself a little protection from the sun. I already own a cap, but this is of the waterproof / resistant variety and doesn't allow my head to breath.
Firstly, the cap had to be breathable. Secondly, it had to fit properly. I haven't got the biggest melon for a head and a lot of caps I briefly considered were just too big. So, after trawling through various websites I settled on this Ben Parkes Elite Running Cap. The information about sizing was key to my purchase and the fact it was really breathable made it a no brainer.
I've since tried it out on my local 10k race this year and I have clearly made the right choice. The day was bright and warm, so these were the perfect conditions to test it out. My face was shaded and the many airholes at the back ensured lots of airflow. The adjustment strap at the back does exactly what it is meant to do. There was quite a bit of wind on race day, and I never felt once that I might lose the hat with a strong gust of wind. I would definitely buy this cap again.
