About UnderAir
Welcome to UnderAir.
UnderAir is here to provide high-quality underwear for men at the best price.
UnderAir underwear is made with their incredibly soft, odor-absorbing SeaWeev, a natural fiber made from Kelp. This incredibly sensational fabric has natural antimicrobial properties that translate to your ding-a-ling staying fresh for up to 5 DAYS!
Their quest for the most ultimate comfort will never end and we guarantee you will be satisfied with your purchase or your money back.
How to create UnderAir underwear?
It all begins with a Tree
Beech Trees are grown and harvest to make pulp for the base fabric. This process is more environmentally friendly and uses 20x less water than harvesting cotton.
Then UnderAir grows Kelp under the Sea
Kelp grows vertically in the ocean making it one of the most efficient crops. After harvest, they extract the essential materials to make SeaWeev with.
Pulped then Spun
The tree fiber is shredded and pulped, then pulled through a filter to make the ultra-soft fibers used in MicroModal. The essential materials from the Kelp harvest are added and spun into yarn.
Yarn becomes SeaWeev
The spun yarn is weaved into a soft, high-density knit and then dyed. It is now SeaWeev and ready for use in their production.
From Fabric to Underwear
From natural raw materials to comfortable apparel. Softer and more colorfast than cotton with anti-microbial and anti-odor properties.
