Hi Matt,
Thanks for the honest feedback—it’s really helpful and I’m sorry to hear the fit wasn’t quite right. You’re absolutely right: the Classic 165mm XXL is designed for wide heads, but the slight inward curve on the arms can feel tight for some face shapes.
Unfortunately, you’re also correct that the material can’t be heat-adjusted without risking damage, so we don’t recommend attempting that.
If your order was in the last 14 days, we can arrange an exchange for a different frame that offers a looser or more open fit—our Sport 165mm XXL or Gent 165mm XXL both have a straighter arm design and tend to give more room around the temples.
Just let me know which option sounds best, and I’ll help you get the exchange started.
