Fit & Sizing

Find the shape that works best for where you sweat.

The Under

2" high × 12" wide × 1" thick

Designed for under-boob sweat. Offers a discrete fit under low-cut tops and sports bras. Of all our styles, we find the Under to be the most compatible with traditional bras. As with any insert, comfort and fit can vary depending on the bra’s construction and support.

The InBetween

4" high × 7" wide × 1" thick

Designed to absorb sweat between the breasts, reduce cleavage friction, and target center under-boob sweat.

The AllTheThings 3"

3" high × 10" wide × 1" thick

Designed for balanced coverage, targeting under-boob and cleavage sweat while helping eliminate friction and chafing.

The AllTheThings 4"

4" high × 10" wide × 1" thick

Designed for maximum coverage, targeting under-boob and cleavage sweat while eliminating friction in between.

Extended+ Under

2" high x 18" wide x 1.5" thick

Targets underboob sweat for women who want more coverage. Designed with a longer length and an extra 1/2" of thickness for increased separation and absorption.

Extended+ The AllTheThings 4’’

4" high x 18" wide x 1.5" thick

Targets underboob and cleavage sweat for women who want maximum coverage for larger melons. Designed with a longer length, 4" of coverage in the cleavage, and an extra 1/2" of thickness to increase separation and maximize sweat absorption.

What is it made out of?

Our Sweatparators are crafted from premium antimicrobial, sweat-wicking fabric and cutting-edge sweat-absorbing foam. All materials are selected for comfort, durability, and effective moisture management.

Designed for Every Body

Every body is different—and every shape works with every body. Our styles aren’t about sizing; they’re about where you sweat. Pick the shape that targets your problem area for the most absorbent, comfortable experience possible.

About the Thickness

For most shapes, the Sweatparator is 1 inch thick. This thickness helps keep the melons separated, reducing friction, preventing chafing and discomfort, and maximizing sweat absorption.

How It Fits

Designed to tuck comfortably in-between and under the breasts—full coverage to the outside of your melons isn’t required for effectiveness.

Materials

We use a high-quality polyester-spandex fabric paired with a carefully selected polyurethane foam—materials that have been safely used for decades in athletic wear, underwear, medical textiles, and personal-care products.

Once manufactured and fully cured, both the fabric and foam are chemically stable, non-toxic, and safe for prolonged skin contact. They do not leach chemicals or absorb into the body and are widely regulated and trusted for everyday use.
We chose these materials intentionally because they:
• Wick and absorb moisture effectively
• Dry quickly and help reduce sweat buildup
• Resists bacteria buildup
• Are soft, flexible, and comfortable against the skin
• Maintain structure and performance over time

Best Bra Pairing

Works best with a sports bra or any other high-compression bra.
