The traditional fly hasn't changed in decades. We changed it. The X-Fly is Crossfly's patented access system — a unique crossover opening that gives you fast, easy, one-handed access without the fumbling, without the exposure, and without the hassle of a standard button fly.
How It Works
Symmetry plays to our advantage, it is the natural way. Two overlapping fabric panels cross at the centre, creating a secure but instantly accessible opening. No buttons. No zips. No awkward angles. Just a natural, intuitive motion that works every time — whether you're at the urinal, on the golf course, or mid-run.
Why It Matters
Fast access — one smooth motion, no fumbling
Access from the top — Shortest distance to reach the Thumb Tab; in our opinion, side access just doesn't cut it.
No exposure — the overlapping panels prevent any accidental gaps
Works with any trouser — compatible with jeans, chinos, suit trousers, and activewear
Designed for Real Life
The X-Fly isn't a gimmick — it's a genuine improvement to everyday comfort and convenience. Once you've used it, a standard fly feels like a step backwards. It's one of the reasons Crossfly customers don't go back to regular underwear. It's so good, we've patented it.
Find It In
The X-Fly features across our IKON and PRO series — available in trunks and boxers, in multi-pack bundles for exceptional value.
