Under Armour Women's Pure Stretch No Show Thong 3-Pack (Style 9CBY)

In this review of the Under Armour Women's 3-pack Pure Stretch No Show Thong, the bottom line is simple: these thongs are built for people who want barely-there underwear that stays discreet under tight workout gear while still feeling soft all day. The standout reason to buy is the new super-soft microfiber stretch fabric, which combines four-way stretch and moisture-wicking performance so the pair works equally well for training sessions and long days on the go.

Key Features

• Super-soft microfiber: New no show microfiber stretch fabric provides a soft, second-skin feel that reduces chafing during activity.
• No-show construction: Flat seams and a mid-rise fit create a smooth, invisible silhouette under leggings and fitted dresses.
• Moisture-wicking: The breathable 4-way stretch fabric draws sweat away from the body to keep skin drier during workouts.
• Stable fit: Designed to stay in place for many users during running and training thanks to the stretch pattern and cut.
• Sustainable packaging: The new packaging is fully recyclable, reflecting a reduced environmental footprint for the product delivery.

Who It's For

These thongs are best for active women who wear fitted bottoms and want underwear that remains invisible and comfortable under tight clothes. Runners and gym-goers who need moisture management and minimal bulk will appreciate the soft fabric and breathability during workouts.

They may be less ideal for those who prefer full coverage underwear or who consistently experience front ride-up with thong cuts; a brief or hipster may be a better everyday choice for that audience. Also, shoppers seeking heavy shaping or compression should look at other styles.
