The Liberty Stadium-based outfit begin their RaboDirect Pro12 campaign with an away trip to Benetton Treviso on Saturday.
And the 24-year-old is determined to build upon a testing summer with Wales in the scorching heat of Japan.
“It was 32 degrees and 67 per cent humidity in the early afternoon and as a front-rower running around I felt my insides were cooking,” said Bevington.
“It sounds ridiculous, but that’s how it was.
“We were getting in at half-time and having packs with crushed ice on our heads and slush puppies as well.
“We had ice on our wrists with the air conditioning on full blast and water thrown all over us. You cooled down but you went back out and five minutes later you felt ill again because it was so hot.
“Japan is a great country with a great culture and I enjoyed the tour. But I struggled with the heat.
“I played 55 minutes in the first Test and everyone loses a few kilograms in the heat.”
Bevington was left out of the second Test with Robin McBryde opting for Rhys Gill and Rhodri Jones in Tokyo.
And he admits he has a point to prove as the season gets underway.
“I was disappointed not to play in the second Test,” added Bevington.
“You are paid to play rugby so you want to play. I was not happy with my first Test performance — maybe conditions got the better of me.
“I spoke to Robin McBryde later and he said he was not too happy, either, so that was fair enough. That was the call and that’s that.
“I’m just looking forward to playing regularly in the campaign ahead.
“Last season was the first time for me to have regular rugby, because for years I was behind Paul James. I would have the odd 20 or 30 minutes each week but did not have many starts.”
