Materials
Fabric composition: 93%TENCEL™ Micro Modal, 7%Elastane
Crafted from fibres spun exclusively for the Just Peachy collection, it retains the same softness and comfort you love from our kids’ line, now reimagined with a denser weave and a higher weight. The result is a material that feels refined to the touch, yet structured enough for outerwear and supportive enough for men’s and women’s essentials.
Just Peachy Underwear is crafted in TENCEL™ Micro Modal, fibers extracted from naturally grown beech wood by an environmentally responsible integrated pulp-to-fiber process. The FSC and Oeko Tex certified modal is biodegradable, free from harmful chemicals and interwoven using Micro technology for a finer quality of lightness and the softest touch.
TENCEL™ Modal fibers are produced by Eco Soft technology, an integrated pulp-to-fiber process that predominantly uses surplus renewable energy from the pulp mill, generating low emissions. An environmentally responsible choice approved by the EU Ecolabel for textile products (license no. AT/016/001).
TENCEL™ Modal fiber types have been certified by TÜV Austria Belgium NV as biodegradable and compostable under industrial, home, soil and marine conditions, thus they can fully revert back to nature.

FAQs
Is the Long Sleeve Thumb Tee suitable for sensitive or eczema-prone skin?
Yes! Our TENCEL™ Micro Modal fabric is recommended by the National Eczema Association. It’s ultra-soft, moisture-wicking, and helps reduce skin irritation compared to synthetic or cotton blends. It's designed without itchy tags or seams, making it gentle on sensitive and eczema-prone skin.
What makes Just Peachy better than typical cotton or polyester tops?
Cotton absorbs sweat but doesn’t dry quickly, while synthetics trap heat and shed microplastics. Just Peachy’s plant-based TENCEL™ Micro Modal is 50% more absorbent than cotton, fast-drying, and completely breathable - ideal for hot or humid climates.
Can the Long Sleeve Thumb Tee be worn all year round?
Absolutely. Its breathable, thermal-regulating fabric keeps you warm in cooler months and comfortable in warmer weather, making it ideal for year-round wear.
What is the benefit of the thumb holes?
Thumb holes help keep sleeves in place under layers, protect wrists and elbows, and reduce unconscious scratching — especially helpful for sensitive skin.
Is the Long Sleeve Thumb Tee suitable for kids, teens, and adults?
Yes. The Long Sleeve Thumb Tee is available in styles designed for kids, teens, women, and men, offering the same comfort benefits at every stage of life.
Is Just Peachy really worth it?
Absolutely — and here’s why parents switch.
Most underwear is made with cotton blends or synthetics that trap heat, shed microplastics, and irritate sensitive skin.
Just Peachy is made with TENCEL™ Micro Modal, a breathable, moisture-wicking, dermatologist-approved fabric that’s loved by kids and trusted by parents.
