If you love the opacity of a contour cup but would prefer less bulk than the usual dense cup padding, then you're sure to love spacer foam bras! The actual fabric of a spacer foam bra has top and bottom layers with vertical filaments that join the two layers, yet let air flow through for breathable comfort. And because it's a knit, this technological wonder has a bit of stretch for a more custom fit. As in other contour bras, these innovative bras have a seamless cup for invisibility under knits like t-shirts. Cup overlays may be silky, smooth microfiber or patterned jacquards that lie flat. Maternity bras with spacer foam cups are especially comfortable for the nursing mother with their cooling, breathable comfort. Plunge fronts, strapless styles, lace trims -- all these can be found in this wonderful new bra innovation. Sports bras with spacer foam cups give you the breathability factor with the additional benefit of heat release to keep you from overheating. HerRoom carries a fabulous selection of spacer foam bras in white, black and fashion colors, also in plus sizes!
