Head coach Chris Horsman has named a group of 27 players to compete in fixtures against South Africa Schools, England and France in three different locations across the Western Cape. Horsman will be joined on the coaching staff by fellow former Wales internationals Geraint Lewis and Richie Rees, with Dragons' James Chapron completing the set-up.
The 2017 edition of the U18 International Series saw Wales record impressive wins against England and South Africa Schools. A sizeable portion of that season's squad wasted little time in stepping up to the U20s, nine of whom - including captain Tommy Reffell - featured at the recent World Rugby U20 Championship in France.
