Dewi Lake and Jac Morgan have been selected as co-captains as Wales announced their 33-player World Cup squad on Monday.
The 33-player squad is made up of 19 forwards and 14 backs with an average age of 27. A total of 17 players have previous World Cup experience.
Hooker Lake and loose forward Morgan have rotated the captaincy during the warm-up games and will share the responsibility in France.
George North, Wales’ most-capped back with 114 appearances, will compete in his fourth World Cup.
Flyhalf Dan Biggar, Wales’ second most-capped back with 109 appearances, scrumhalf Gareth Davies, tighthead prop Tomas Francis, blindside flanker Dan Lydiate and fullbacks Leigh Halfpenny and Liam Williams will all compete in their third World Cup.
Flyhalf Gareth Anscombe and No 8 Taulupe Faletau have both made the cut, despite not featuring in the warm-up games.
There is no place for New Zealand-born loose forward Taine Plumtree, who made his Test debut for Wales this year.
“The toughest part of the job is always selection and this is particularly the case when it comes to picking a Rugby World Cup squad,” said Warren Gatland.
“Over the past three months the whole group of 48 players in the wider training squad has been outstanding in terms of attitude and effort, so having to reduce the squad down to the final 33 has been really hard and there have been some close final decisions in the last 36 hours.
“But we can only take 33 players and those we have selected we think offer a good combination in terms of talent and experience.
“We have a few more training sessions here in Wales before we depart for France on 3 September and we cannot wait to get out there and get started in this tournament. We look forward to what lies ahead for this group.
“This will be a very proud moment for these players, their families and friends and I’d like to congratulate them all on the achievement.”
Drawn in Pool C, Wales’ World Cup campaign in France begins against Fiji in Bordeaux on Saturday, 10 September. The squad then travels to Nice to play Portugal on 16 September, before facing Australia in Lyon on 24 September, and meeting Georgia in Nantes on 7 October.
