The first layer you put on in the morning sets the tone for your entire day. Whether it’s a lightweight undershirt, a cozy tank, or a breathable bodysuit, your base layer determines how comfortable you’ll feel physically and mentally.
Why Base Layers Are Important
Synthetic base layers, like polyester or nylon, often trap sweat, causing discomfort, odors, and even skin irritation. Worse, they release microplastics with every wash, polluting our oceans. In contrast, sustainable fabrics such as organic cotton, bamboo, and TENCEL™ are breathable, moisture-wicking, and naturally hypoallergenic.
When your skin can breathe, your body regulates temperature more effectively, reducing stress and fatigue throughout the day. Choosing sustainable base layers is not only a health-conscious decision but also an eco-friendly one.

How to Choose the Right Base Layer
-
For everyday wear: Opt for organic cotton undershirts and bodysuits. They’re soft, breathable, and versatile.
-
For workouts: Go with bamboo or hemp-based activewear that wicks away moisture naturally.
-
For lounging or sleeping: TENCEL™ sleepwear regulates body temperature and promotes deeper rest.
Caring for Base Layers Sustainably
Cold washes and line-drying not only preserve fabric integrity but also reduce your household energy footprint. Spot-cleaning delicate fabrics helps extend their lifespan and keeps your clothing rotation fresh.
