The Connacht squad gave amused fans a first glimpse of the huge jersey before inviting Mils Muliaina, as a 'welcome to Connacht' gesture, to be the first Connacht player to sign the jersey.
The Life Style Sports' sponsorship of Connacht Rugby includes exclusive branding of all playing and training kit for the Connacht senior squad over four seasons.
Commenting on the new partnership and his arrival to Connacht Rugby, Muliaina said: "It's great to finally be here in Connacht. The welcome I've received from everyone, including Life Style Sports today in the city, has been amazing.
"I'm really excited about settling into life in Galway, getting to know my team-mates, the supporters and working closely with partners like Life Style Sports.
"The season kicks off in just over a week and I'm keen to get stuck in straight away to the mentoring role Pat (Lam) has set out for me. I'm so hungry to play and will continue rehab work on my elbow so I'm fighting fit for the end of October."
