Mandatory requirement that XT Polo Shirts are worn when delivering lessons or at related ADI functions when representing XT.
The Polo Shirt  is Navy Blue and available in either normal or wicking material:

(Wicking fabrics are modern technical fabrics which draw moisture away from the body. They are made of high-tech polyester, which, unlike cotton, absorbs very little water. Cotton will absorb 7% of its weight in water, polyester only 0.4%. Cotton will therefore hang onto your sweat, making your garment heavy and unpleasantly clammy. Wicking polyester has a special cross-section and a large surface area, which picks up moisture and carries it away from your body, spreading it out, to evaporate easily on the outside of the fabric. So you stay cool and dry.

Some people will refer to wicking fabrics as being breathable – that is, they let air in and sweat out. Breathable showerproof and waterproof fabrics have tiny pores in the fabric, larger than water vapour molecules (so these can get out) but much smaller than drops of rain (so these can’t get in).

Note the use of BLACK Shirts is now deprecated. Existing ones may still be worn but replaced with navy.
