Unlike traditional undershirts, Numi is designed with innovative Contemporary Cotton™ sweat-proof technology, providing all-day protection against sweat, odor, and stains. Our moisture-wicking and breathable fabric prevents sweat from soaking through to your outer layers, keeping you dry and confident.

Absolutely! Numi pieces are made for real life. All our garments are machine washable, so you can toss them in with your regular laundry. No special detergents or dry-cleaning required. Our high-performance fabrics are designed to maintain their softness, shape, and sweat-proof protection, even after repeated washes. Simply follow the care instructions, and enjoy long-lasting wear.

Feeling great starts with the right fit. Numi pieces are designed to fit snugly yet comfortably, ensuring a smooth, invisible fit under clothing. We recommend checking our detailed size guide, which includes measurements for bust, waist, and hip to help you find your perfect fit. If you're in between sizes or need extra guidance, our customer support team is always happy to assist you.

Numi is made with premium, sustainable materials that offer sweat protection, breathability, and long-lasting wear — helping you save on dry cleaning and keep your clothes fresh longer. Many customers find that our garments are an investment in their wardrobe.

We want you to love your Numi pieces! If for any reason you're not satisfied, we offer hassle-free returns within 30 days. Simply ensure the items are unworn, unwashed, and in their original condition with tags attached.
