Sweat Absorption

Sweat absorption refers to a yoga mat's ability to take in perspiration rather than letting it accumulate on the surface. This property determines how a mat performs during hot yoga, vigorous vinyasa, or any practice where sweating is significant.

Two Approaches to Sweat

Absorption (open-cell/fiber materials): The mat surface soaks up sweat, keeping the top relatively dry and maintaining or improving grip. Microfiber, faux suede, and open-cell rubber surfaces work this way.

Repulsion (closed-cell materials): The mat surface does not absorb sweat — moisture stays on top. PVC and many TPE mats work this way. This is actually hygienic (easy to wipe clean) but creates a slippery surface when sweat accumulates.

Why It Matters for Hot Yoga

In a hot yoga class, the difference between these approaches is dramatic. A practitioner on a non-absorbent mat (PVC) in a humid 105°F room will have their hands and feet sliding on a wet surface within 20 minutes. A practitioner on a microfiber-top mat in the same conditions will experience improving grip as the surface absorbs sweat.

The Yoga Towel Solution

For practitioners who prefer non-absorbent mats (PVC, standard rubber) but practice in sweaty conditions, a yoga towel placed over the mat provides an absorbent layer. This is common practice in Bikram and hot yoga studios worldwide.

Saturation Limits

Absorbent mat materials have limits — they can become saturated in extremely sweaty conditions. Mats with high absorption capacity (thick microfiber layers) handle more sweat before performance degrades.
