Primal Europe will provide the kit for Welsh Cycling's youth, junior and U23 programmes in a three-year deal, starting in April.
Welsh Cycling CEO Anne Adams-King said: “It’s a delight to team up with such an innovative and reputable brand who share our passion for cycling in Wales."
New kit will be unveiled in the Spring.
In addition to the Welsh athlete programme on- and off-bike kit, Primal will provide championship podium jerseys, which are awarded at eight Welsh cycling championship events per year within eight different disciplines, including road, time trial, criterium, track, MTB XC, MTB DH, cyclo cross and BMX.
Primal Europe director James Smith said: “We are delighted to be collaborating with a national governing body that reflects our shared values of innovation and performance."
