UltraLyte™

Meet UltraLyte™, our lightest fabric yet. We've taken our four best-selling underwear styles and remade them in a silky-soft, seamfree bamboo fabric so light, you'll barely know you're wearing it.

 

Made from 89% viscose made from bamboo and 11% elastane, with no nylon in the main fabric, UltraLyte™ has superior stretch for an airy fit that moves with you. Each pair is finished with a soft bamboo and Australian cotton blend gusset. It's lightweight underwear for women that keeps up with warm days, travel and everything in between.

The Lightest of Ultra Light Underwear

UltraLyte™ is made for the days you want to feel like you're wearing nothing at all. The breathable fabric is naturally moisture-wicking and temperature-regulating, helping you stay comfortable when the weather heats up, and odour-resistant for all-day freshness.

 

If you already love our Bamboo Seamfree underwear, think of UltraLyte™ as its lighter, silkier sibling: the same seamfree comfort, with even more stretch and a barely-there feel. It's also OEKO-TEX® certified and made without PFAS, so it's gentle on skin from the first wear.

Shop Lightweight Underwear for Women in Our Best-Selling Styles

Every UltraLyte™ style is an exact replica of a Boody best-seller, so you already know the fit. Choose our No. 1 best-selling Full Briefs for a high rise and full coverage, or the mid-rise Midi Briefs for full bum coverage without the high waist. For less fabric, the low-rise Classic Bikini offers moderate coverage, while the minimal-coverage G-String is designed to minimise visible underwear lines under clothing.

Each UltraLyte™ style is an exact replica of one of Boody’s best-selling underwear shapes, with a lighter, stretchier fabric. Its innovative seamfree construction and bamboo filament fabric offer superior stretch, allowing the underwear to move comfortably with your body.

To keep your Boody UltraLyte™ Underwear feeling soft and comfortable, machine wash cold with similar shades on a gentle cycle. Do not bleach, tumble dry, iron or dry clean. Line dry in the shade to help maintain the fabric's softness, stretch and shape, so you can enjoy lightweight, seamfree comfort wash after wash.
