You can buy other custom one piece textile suits, yes. But they aren't going to offer the kind of fit that many women need (hips, waist, thighs!). Featuring great armor, front cargo pockets, waterproof zippers and more. The price point is definitely high ($899), but certainly appropriately priced for a fully custom suit measured to your needs and fit for a woman, not a man.
Even the SAS-TEC Armor that they used are sized and shaped specifically for women. No detail has been spared!
I haven't had any personal experience with one, but I do know that every effort has been made to make this suit truly fit and work for us.
