For 150 years, Chantelle has innovated in the fabric space, using this innovation to drive product design forward to the benefit of women’s comfort. For many women, part of that comfort is not being overly aware of their undergarments. We want to know our bras are doing their job, but not necessarily feel them doing it. Wearing a bra that’s heavy on the body, especially in warmer months, feels oppressive, sweaty, and hot. Thankfully, newer fabric technology means never having to peel a sticky bra off your body again. 

That’s where spacer fabric comes in. Sounds futuristic, right? Well, as a literal 3D fabric, it kind of is. Unlike traditional 2D fabrics, which consist of a single layer, spacer fabric is a highly engineered material made of two separate fabrics joined by a layer of vertical yarns that create space between the two fabrics, and, with that space, air. The result is added breathability and lightness, with air flowing freely between the layers, which helps regulate temperature for a cooling effect and prevents moisture buildup.

Within the world of spacer bras, Chantelle offers a variety of coverage levels and wardrobing solutions. Check out some of your sure-to-be-favorites below.

The newly launched Belle Plunge T-Shirt Bra is light in both feel and coverage. The spacer t-shirt bra cups provide a low plunge neckline, plus the airy feel that spacer is known for. The low neckline plus j-hook functionality make this style a travel must-have - it goes under everything and the cups won’t get crushed in your suitcase. Perfect for everyday and those summer travel plans, up to an H cup.

The Norah Comfort Spacer is comfort first, putting soft fabrics and that spacer-lightness to good use. The full coverage cups fully contain the bust using a jacquard spacer fabric featuring the Norah floral pattern woven into the cup. The integration of this pattern gives the cup just a touch of added rigidity for a recentering effect through the bust. The buttery soft knit band smooths the back, and straps have a j-hook for convertibility, for ultra comfort and wardrobing versatility up to an I cup.

Both the cup AND the band of the Magique Seamless Unlined Minimizer are lined with a light spacer fabric that has a firm stretch to it, so in addition to being breathable and light, it also works to smooth and shape, while providing softness and comfort. Magique provides side and back smoothing, minimizing and contouring without compressing. This cooling and minimized, but not flattened, style is available up to a J cup.
