When we designed our Modal Cotton collection, we were on a mission to make our Thinx period underwear *even* softer and more sustainable. Oh, and spoiler alert: we did just that.

Using consciously-sourced materials, our unique cotton blend offers a more eco-friendly and cozy option for your period week (and beyond).

what is Modal Cotton?

Well, it’s 53% SUPIMA® Cotton, 35% TENCEL™ Modal, and 12% Elastane, to be exact. This upgraded cotton blend uses less water during production — a more sustainable choice than pads, tampons, & other period underwear.

SUPIMA®️ cotton is grown in the USA and constructed with higher quality raw materials, making it softer, stretchier, and more durable than regular cotton. TENCEL™️ Modal is a plant-based textile made from beech tree pulp, which is biodegradable. The resulting blend is an all-natural fabric with a superior feel — that just so happens to be our most breathable, lightweight, and planet-friendly fabric yet.

why SUPIMA® Cotton?

SUPIMA® Cotton is constructed with high quality raw materials, resulting in a silky smooth and buttery-soft texture. So not only is it inherently softer on your skin and more luxurious than regular carded cotton — there’s also the added bonus that it resists pilling and gets *even* softer over time. Our Modal Cotton period underwear styles also feature extended gussets in both the front and the back for extra leak coverage. Win-win-win.

Plus, the SUPIMA® cotton in our Modal Cotton period underwear collection is sourced through the Better Cotton Initiative (BCI). BCI is a non-profit organization focused on improving ethical global cotton production for farmers and environmental impact. They own and steward the Better Cotton Standard System — a system which encompasses a diverse range of activities and stakeholders from cotton production, through the cotton supply chain to consumer-facing retailers and brands.

what makes this blend more sustainable?

TENCEL™ Modal fibers originate from renewable raw material beech wood, sourced from sustainable forests, and are compostable and biodegradable. TENCEL™ Modal has a lower environmental impact than generic modal, using 3x less water and depleting 8x less fossil fuels. Plus, due to its natural properties, TENCEL™️ Modal retains superior quality & performance over time.

can I wear Thinx Modal Cotton if I have sensitive skin?

Our Modal Cotton collection is an excellent choice for those with sensitive skin. As an all-natural fabric, Modal Cotton should not irritate your skin if you typically wear cotton, and should only get softer over time with washing.

what colors & styles are available in Modal Cotton?

Our softest, most eco-friendly period underwear comes in five colors: 

1. Fir — a moody, mossy green

2. Canyon — an earthy, pink-toned terracotta

3. Slate — the hue of a mountaintop summit that's been smoothed by the wind

4. Black — like the sky on a starless night during a new moon

5. Houndstooth — our cool-blue-toned take on the classic print

Our Modal Cotton collection consists of four essential underwear styles in a range of absorbency levels, for cozy-comfy protection from your lightest to your heaviest days.

1. Cotton Brief — a classic full-coverage style, available in our super, heavy, and moderate absorbencies for cycle-long protection

2. Cotton Boyshort — a full-coverage, gender-neutral style with a lil’ extra length in the leg (absorbs 5 regular tampons’ worth of flow)

3. Cotton Bikini — an everyday bikini silhouette with a slightly higher rise (absorbs 3 regular tampons’ worth of flow)

4. Cotton Thong — a minimal-coverage style that’s perfect for those just-in-case days (absorbs 1 regular tampon’s worth of flow)
