TMT Core-Heat Sweat Belt - Compression

Size Guide

Start here: our sizing runs small

Most of our activewear is manufactured to Asian sizing, which runs roughly one size smaller than standard US sizing. If you normally wear a US medium, our large will usually be the better fit.

If you are between two sizes, take the larger one.

The reliable way to get this right

Do not convert sizes. Measure a garment you already own and like the fit of, lay it flat, and compare those numbers to the measurements on the product page.

Every product description lists the measurements we have for that specific item. Where we have a full chart, it is printed on the product page itself — because a shorts chart and a leggings chart are not interchangeable.

How to measure yourself

• Bust — around the fullest part of your chest, tape level and snug but not tight.
• Waist — around the narrowest part of your torso, usually just above the navel. This is where a legging or short waistband sits, not where jeans sit.
• Hip — around the fullest part of your hips and seat, feet together.
• Inseam — from the crotch seam straight down to the ankle.

Measure over close-fitting clothing or bare skin, not over a jumper.

Example charts

These are the full charts we hold for specific products. Use them as a guide to how our sizing behaves, but always check the product page for the item you are buying.

Scrunch Biker Shorts (cm, laid flat)

Skinny Summer Shorts (cm, laid flat)

Loose-Fit Yoga Tank (cm, laid flat)

This one runs particularly small — our L sits closer to a US small or medium.

Allow for measuring variance

All measurements are taken by hand and laid flat, so allow 2-3cm either way. On items with a built-in bra or heavy compression, allow up to 4cm.

Still not sure?

Email info@gearrup.com with the item and your measurements and we will tell you which size to take.

And if it arrives wrong, our returns policy covers you for 30 days. On items under $30 we refund in full and in most cases you will not need to send anything back.
