Scrumhalf Aled Davies was the only uncapped player in an experienced 37-man squad named by Wales for the Six Nations tournament.
There were recalls for Cardiff Blues wing Tom James - six years since he last played for his country - and Josh Turnbull, who was last capped in 2014, in a squad led by captain Sam Warburton.
Backs Liam Williams, Jonathan Davies and Hallam Amos return after injury.
"We have selected a squad that rewards players form as well as picking a lot of experience and that continuity is important to us," coach Warren Gatland said in a Welsh Rugby Union statement.
"We have picked a larger squad than normal, we have a few injuries at the moment, those players aren't too far away from getting back on the field so we are happy with the mix," he added.
"Aled is someone who has been on the radar the last couple of years and his selection is reward for his form. Tom is playing very well for the Blues and we have been impressed with Josh's performances recently."
Wales kick off their campaign away to champions Ireland on Feb. 7 and host Scotland on Feb. 13.
