"All 28 guys in our squad have earned the right to wear the black jersey, so there was a lot of discussion around our selection. We have chosen an experienced team to kick off the tournament," Philpott said.
"We expect Scotland to be direct, physical and passionate on both attack and defence, so we have picked our team accordingly.
"Obviously, we want to make a good start to the tournament. It's been the best part of three weeks since the Oceania championship, so we want to get back up to where we were at that tournament in terms of our attack and defence."
Scotland placed fifth in the Six Nations Under 20s, defeating only pool opponents Italy, though the scoreline was 20-19 against Ireland, also in their pool.
Other potentially interesting day one clashes see England take on Samoa and Australia versus Wales, while South Africa will clash with France and the hosts Georgia face Argentina.
The second round of matches is on Sunday, with New Zealand facing Italy at 11.30pm NZT.
Kickoff is at 9pm tonight.
