SeaCell™ is a premium material with antioxidant properties that does not irritate the skin. The minerals and amino acids from seaweed are preserved in the fabric, delivering natural moisturizing and soothing effects every time it touches your skin. Additionally, seaweed is harvested only from the regrown parts rather than being freshly collected each time, making it environmentally friendly.

Smartcel™ protects the skin with UV protection (UPF 50+) and antibacterial and deodorizing effects at the same time. It is not just a 'breathable sportswear,' but is designed to keep you comfortable even under the sun or during long hours of wear.










Many hands are involved before this garment reaches you. We respect the hard work and skills of everyone who makes NUVAIV products.'I Made Your Clothes' message began as a movement to bridge the gap between makers and consumers in the global fashion industry. In sympathy with this message, we introduce our makers. Every piece you wear contains someone's dedication and story.


Reason for Reward Development
It started with the idea of creating a new daily wear that combines both 'activity and style.' Comfortable like sportswear, yet maintaining a sophisticated silhouette for urban looks, we blended SeaCell™ extracted from seaweed and Smartcel™ yarn containing natural zinc to create a skin-friendly yet resilient top. We aim to make it not just simple activewear, but a daily fashion item that naturally follows your movements.
Frequently Asked Questions
Q. Is this product sportswear?
A. The NUVAIV off-shoulder top is more of a hybrid wear that connects sports and daily life rather than just 'sportswear.' It is comfortable for light activities such as yoga and pilates, but also designed to be stylish for casual outings.
Q. I heard the fabric is special. What kind of material is it?
A. This product is made from eco-friendly materials using SeaCell™ and Smartcel™ yarns from Germany's Smartfiber. SeaCell™ fiber, extracted from seaweed in the clean seas of Ireland, has antioxidant properties and excellent moisture absorption, while the zinc-based Smartcel™ fiber offers antibacterial and UV protection functions. Our self-developed eco-friendly fabric, utilizing these two components, reduces irritation for sensitive skin and provides comfortable wear all day long.
Q. What body types does it fit well?
A. It is a body-hugging design made from highly elastic fabric. Please choose your usual size, but if you prefer a looser silhouette, we recommend going up one size.
Q. What is the refund/exchange policy?
A. Finishing details that may occur during production (such as loose threads or chalk marks) are not considered defects. Damage caused by improper washing cannot be exchanged or refunded, so please be sure to check the washing instructions. For more details, please refer to the refund/exchange policy.
Maker Introduction
"Why do we have to choose between comfort and style in clothing?"
Nuvaiv began with this question.

Hello, I am Sunghee Um, the CEO of Nuvaiv. With 18 years of experience as a product planning MD at domestic and international fashion companies, I have always thought about 'how to naturally connect exercise and daily life with a single piece of clothing.'
As a result, the brand Nuvaiv was born.
Nuvaiv is a hybrid wear brand that combines comfort for movement and a sophisticated style, offering silhouettes that are as comfortable as sportswear and naturally suit any moment, such as walks, café tours, or short outings.
Nuvaiv also aims for a sustainable fashion ecosystem, producing more than 70% of all products with eco-friendly materials.
With the goal of reaching 100% by 2026, we are implementing processes that minimize environmental impact from the material stage, using self-developed materials including seaweed-based yarns.
Nuvaiv is a lifestyle wear brand with a new mood for people who care about the environment, offering the most natural everyday style made from good materials.
Reason for Wadiz Funding
Through Nuvaiv's first eco-friendly material line, the SeaCell™ & Smartcel™ Collection, we aim to connect with conscious consumers and spread the value of sustainable fashion more widely.
