Product or Service Categories
Light Flow Underwear
This category includes underwear designed for lighter menstrual days or as a complement to other products. These styles generally feature thinner absorbent layers while maintaining the brand’s typical comfort-focused construction. They may appeal to those who want a subtle option early or late in their cycle.
Moderate Flow Underwear
Flux Undies offers mid‑range absorbency options intended for average flow days. Examples in this category combine familiar underwear shapes with discreet absorbent layers. This section of the range often serves as an entry point for new customers deciding whether period underwear fits their lifestyle.
Heavy Flow Underwear
Designed for users seeking higher absorbency, this category includes thicker protective layers suitable for heavier days. The brand maintains its basic silhouettes while increasing coverage in areas where additional protection is typically preferred. These designs position the brand as a practical choice for varied cycle needs.
Super Heavy Flow Underwear
Some Flux Undies products are structured for very high absorbency. These items aim to support users who prefer maximum protection in a reusable format. They tend to feature more substantial layering, making them one of the brand’s more specialised categories.
Period Shorts
A selection of period shorts provides an alternative to standard briefs. These items generally offer more coverage and can be suitable for comfort-driven use cases or overnight wear. The category demonstrates the brand’s effort to broaden style choices while keeping absorbency consistent.
Maternity and Postpartum Options
Flux Undies includes products designed for postpartum needs, offering absorbency suitable for post‑birth experiences. These items often feature gentle materials and fuller coverage, aligning with the comfort‑first positioning that runs throughout the brand’s offering.
Teen Range
Teen‑friendly designs form another part of the Flux Undies catalogue. These styles usually incorporate accessible silhouettes and straightforward absorbency levels. The brand presents this category as a user-friendly introduction to period underwear for younger individuals.

The brand offers swimwear incorporating light absorbency intended for use in water. These items generally mirror standard swimwear designs, with added protective layers suitable for lighter cycle days. This category demonstrates the brand’s attempt to expand its product groups beyond underwear alone.
