I am also in the clydesdale "division"

Wore these: https://www.amazon.com/gp/product/B076PP83VP/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Wore them under my wet suit, then biked and ran in them. For the T1 I changed in to a bright yellow tank top from Target, Champion brand, and biked and ran in that. Worked great and family could see me a mile away.
