3 Reasons Why The "Long Shift" underwear is

A Game Changer

BEST FOR "LONG SHIFT" DAYS

Are you in need of underwear that will keep up with your long shift days? If so, these seamless bikinis made from a nylon and elastane hybrid are perfect for you. Unlike underwear designed for regular days, the SilverAir line has no cotton gusset—“that little pocket in the center that really doesn't have a purpose in activewear.”. Underoutfit uses Silver yarns in the fabric that prevents the development of bacteria, a key cause of infections. Cotton is not always breathable and may irritate some people.

NO COTTON GUSSET

Cotton is a great fabric for low-impact activities, but when it comes to sweating, it does not cut it. Did you know that 90% of everyday underwear is lined with cotton gussets that trap moisture and breed bacteria? The fabric used in Underoutfit's design is unique nylon-spandex, which has antimicrobial properties. As a protective barrier, it keeps moisture away from your skin and keeps you dry where it matters most. 

SEAMLESS PERFORMANCE

There is no rolling or shifting. There's nothing more distracting during a long day than constantly having to readjust what you're wearing. Underoutfit's wide, seamless band lays flat on your skin and stays in place even during the most intense days and movements. You can move freely, your underwear won't.

Natural Breathability

Next-To-Skin Comfort

Crafted with premium natural materials, our silky-smooth underwear stays so dry and fresh throughout the day, it's like going au naturel.

A TIP:

TRY AT HOME

Since you get free exchanges and free returns for a 100% full refund, why not try it out at home? At your comfort.


60 Days to wash and wear

You can order two different sizes or even a few colors to try at home. If you don't like it or it doesn't fit well, just send it back or exchange it for another size... It's free, and Underoutfit pays for the shipping too 😊.
