Training thongs: the G-string built for the gym

Short answer: a training thong is a G-string built for the gym, not for looks. The whole point is a seamless, moisture-wicking pair that stays put through a workout, does not show under leggings, and keeps you dry when you sweat. If your only experience of thongs is a flimsy pair that rides and digs, a training thong is a completely different thing. Here is what makes one work.

What is a training thong?

It is a G-string designed for movement and sweat rather than a night out. Instead of thin elastic string and a decorative fabric, a training thong uses a breathable moisture-wicking knit, bonded flat edges so nothing chafes, and a cotton-lined gusset. It is the underwear equivalent of the difference between a fashion sneaker and an actual running shoe.

Why wear a thong to the gym at all?

Two reasons, and both are practical. First, no visible line: gym leggings are thin, and a seamless G-string is the only cut with no back seam to print through (why here). Second, no ride: with less fabric and flat bonded edges, there is simply less to shift, dig or bunch mid-squat. It is not about how it looks. It is about not thinking about your underwear during a workout.

Does a training thong help with sweat?

Yes, if it is made from a wicking knit rather than cotton. Cotton soaks and holds sweat; a breathable performance knit moves moisture and dries fast, so you stay dry through a hot class. The cotton-lined gusset keeps the sensitive part soft and breathable. Together that is a pair that handles sweat and VPL at the same time.

What if you have written off thongs?

Fair, most people who avoid thongs have only worn bad ones. A properly built training thong with bonded edges and the right fit does not ride, dig or feel like floss. If you want the full case, we wrote how to get comfortable in a thong. For the gym specifically, it is often the most comfortable option once it is a good one.

The best training thong, in short

Seamless G-string, moisture-wicking knit, cotton-lined gusset, bonded flat edges, in your size. That is a training thong that disappears under leggings, stays put and keeps you dry. It is exactly what we built the Anywhere G to be, from $21.90 a pair in packs.
