I had to ride without a noseband at first 😂
My PRE def has this head. He wears a BR rolled leather bridle for his snaffle in Full and a Schockemöhle Venice for his double, also Full. The Schockemöhle has a generous noseband, so perhaps their snaffle bridles would too.
I tried Bridle2Fit (the customer service was a bit rubbish) when I was looking for a drop and none of their nosebands were big enough. Otherwise, these types of companies where you can piece together something would work.
I’m not a fan of Eponia, but the bridle I had from them also had a roomy noseband (Frost bridle).
A Full size browband just fits him, so no oversize needed, but browbands are so easy to find nowadays.
Not sure how short yours is in the neck, but I found using Cob size reins (from PS of Sweden, in this case) quite suitable. Just the right length and doesn’t leave so much extra when you shorten the reins.
