UltraLyte™
Meet UltraLyte™, the lightest fabric we've ever made. Our four best-selling underwear styles, reimagined in a silky-soft, seamfree bamboo fabric so light, you'll forget you have it on.
UltraLyte™ is made from 89% viscose made from bamboo and 11% elastane, with no nylon in the main fabric (only in the trims), giving it superior stretch and an airy fit that moves with you. Every pair has a soft gusset blended from viscose made from bamboo and Australian cotton. It's lightweight underwear for women, made for hot days, travel and everything in between.
The Lightest of Ultra Light Underwear
UltraLyte™ is designed 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 as the temperature climbs, and odor-resistant to keep you feeling fresh all day.
Love our Bamboo Seamfree underwear? UltraLyte™ is its lighter, silkier sibling, with the same seamfree comfort plus extra stretch and a barely-there feel. It's also OEKO-TEX® certified and made without PFAS, so it's gentle on skin from day one.
Shop Lightweight Underwear for Women in Our Best-Selling Styles
Each UltraLyte™ style is an exact replica of a Boody best-seller, so you already know the fit. Go for our No. 1 best-selling Full Briefs for a high rise and full coverage, or the mid-rise Midi Briefs for full rear coverage without the high waist. Prefer less fabric? The low-rise Classic Bikini offers moderate coverage, while the minimal-coverage G-String is designed to minimize visible underwear lines under clothing.

SHOPPING MADE RELATABLE
Boody is committed to making your shopping journey as comfortable as our products.
From your feedback, we know it helps to see our pieces on someone who represents your shape and size. That’s why we’ve made it easier to shop for a more diverse range of body types. This isn’t a stock filter - it’s about visuals. We’ll display models across Small, Mid, and Plus size groupings, and you can always select non-model images too.
A style may still be available in your size, even if we haven’t yet photographed it in your selected size, so we recommend checking the product detail page or using our size filter to be sure.
It’s not perfect yet, but we’re listening to and learning from our community, and are committed to investing in more diversity in model shapes and sizes.
