Vapour-X Microlight Short Sleeve (Women's)
Apart from the garish colour, which actually will be really useful once it starts to get darker in the evenings, this is a really nice t-shirt. It's lightweight and feels really soft against the skin, so I don't imagine there would be any issues with chafing!
The sustainable fabric is breathable, wicking and anti-microbial (so you won't smell!). It's Bamboo Charcoal Technology also boasts that it will protect from UV rays and promote cell activation and blood circulation!
Air Head Visor
While I don't appreciate having the label "Air Head" (haha), I do love this visor! Again it's quite bright, and would be great for reflectivity and visibility at night, but then again do you need a hat to keep the sun out of your eyes at night?! It is very comfortable though, and being a visor rather than a cap doesn't make your head too hot when exercising.
It also has a soft towelling stretch band so will fit any size head, and acts as a sweatband when exercising.
