We get it. It's tough to decide which fabric of underwear to get, especially without touching and feeling it yourself.
Here, we'll help you get a feel for each option so you can confidently choose the best underwear for your needs.
Bamboo (Viscose): Soft, Silky, and Breathable
If you’re looking for something that feels ultra-soft and cool all day, bamboo (viscose) is a clear winner. Why?
- Soft – gentle on skin, especially sensitive areas
- Silky – smooth to the touch, feels premium
- Breathable – helps prevent overheating and irritation
Best for:
- Everyday wear
- Lounging
- Casual outings
- Warm climates or people who tend to run hot
We typically recommend bamboo for customers who want comfort first and foremost. It’s especially great for staying cool and dry throughout the day without feeling restricted.
Polyester: Durable, Quick-Drying, and Snug
Polyester is a performance-driven fabric designed for tougher conditions. Why?
- Durable – holds up to repeated wear and washing
- Quick-drying – ideal for sweaty or wet conditions
- Snug – offers a closer fit for added support
Best for:
- Exercise and sports
- High-heat or physically demanding jobs
- Travel and outdoor adventures
- Situations where you know you'll be sweating (since it dries fast)
Polyester is a great choice when you need underwear that can keep up with you and bounce back day after day.
What if I'm Recovering?
If you're shopping for post-surgery or medical recovery, both fabrics have their advantages.
We typically recommend bamboo for recovery because it’s softer, gentler, and less abrasive, which can be important when the skin is sensitive or healing.
That said, some people prefer polyester because of its more compressive, snug fit, which can offer a feeling of support or security around the surgical area.
As always, comfort is key during recovery. If you're unsure, bamboo is usually the safer bet, but if you’re looking for a little more structure and support, polyester may be the better choice.
Fit Tip: Bamboo vs. Polyester
Some customers notice that our polyester styles fit more snug than bamboo. That’s true, polyester fabrics generally have less natural stretch compared to viscose, which is looser and more fluid by nature.
If you’re between sizes or prefer a looser feel, you might consider sizing up in polyester or sticking with bamboo for a more relaxed fit.
Conclusion
There’s no one-size-fits-all answer — it really depends on your lifestyle. If you prioritize comfort and breathability, go with bamboo (viscose). If you need something tougher, more supportive, and sweat-ready, polyester is your go-to.
Still not sure? Many customers end up trying both and rotating them based on the day ahead.
