CompuDude:I know we tried the Aqualung Tyke (or was it the Tyke Midi, or both? I can't recall.) and it was very close, but the fit was not as good as the Sporasub.
Sport Chalet probably carried 30-40 different masks, but only a few are for small faces... and of those, only the one seemed to actually fit her tolerably well. We'll try more this weekend, however.
CompuDude,
There are a couple of masks out there for smaller faces and I've tried most of them because I too have a long narrow face LOL!
If possible let her try out these masks:
Cressi Lince
X Vison Mid
The X Vision and Pure Vision both broke on me and their replacements failed too so personally I'm not too keen on getting another mares mask soon but they work for some just not for me.
Although these masks are not designed for smaller faces they tend to fit most very well:
Atomics
Poseidon 3D
Surprisingly there are many masks out there that although not designed for specific faces do fit quite well and no harm trying out as many as you can instead of just focusing on the few designed for smaller faces. Don't forget the freediving masks too.
