🧣 Customizable PLA Thermal Underwear Set by Sincdoo – Soft, Warm & Eco-Friendly
Sincdoo offers customizable PLA thermal underwear sets designed for both men and women who seek warmth, skin comfort, and sustainability. Crafted from our proprietary PLA fabric—derived from corn, sugarcane, and straw—these garments are biodegradable, breathable, and microplastic-free, offering a thoughtful upgrade from petroleum-based thermal wear.
Ideal for cool to moderately cold seasons, this collection provides just the right thickness for insulation, without compromising on softness or breathability, making it suitable even for sensitive skin.

✔️ Thermal insulation with breathability: Keeps you warm while preventing stuffiness
✔️ Soft and non-irritating: Gentle on sensitive skin, no stickiness when sweating
✔️ Moisture-wicking & quick-drying: Perfect for day and night wear
