Fresh from recently being crowned Arnold Clark Women’s Premiership champions, Stirling County duo Holland Bogan and Ceitidh Ainsworth will co-captain the side this weekend.
In the front row, Megan Hyland will pack down alongside props Freya Gracie and Imogen Spence.
Stirling County locks Bogan and Gemma Thomson will link-up in the second row, while Samaanther Taganekurukuru, Gemma Bell and Emily Coubrough make up the back row.
Rianna Darroch and Ainsworth will pull the strings at scrum-half and stand-off respectively, with Briar McNamara and Nicole Flynn chosen as the centre partnership.
Hannah Smyth and Sky Phimister will line-up on the wings, with Poppy Mellanby completing the back three at full-back.
Speaking ahead of the opening match of the season, Head Coach Smith said: “I’m looking forward to the match and I know the players are excited as well. It’s a great opener to our Celtic Challenge campaign as we finished the last season against Brython so it’s a good opportunity for us to revisit that fixture.
“We know that the Welsh sides love the contact area and will bring physicality to the contest. I think that is something we will need to match and be better than them in certain areas of the field.”
