Overview

The Gruper NBR-01 is an exercise mat made from nitrile butadiene rubber (NBR) foam, weighing about 1.8 pounds in a brown colorway. NBR foam is generally softer and more cushioned than TPE or thin PVC mats.

NBR is the closed-cell foam commonly used where extra padding matters more than minimal weight, so this mat prioritizes cushion over the ultralight portability of a TPE mat. It sits at a middle weight for a home exercise mat.

  • Nitrile butadiene rubber foam
  • 1.8 pounds total weight
  • Brown colorway
  • Model NBR-01

Who it's for

Works well for floor exercises, stretching and mat routines where knees and elbows contact the ground often. Travelers wanting the lightest possible roll-up mat may prefer a thinner TPE option instead.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • NBR foam gives extra cushion for knees and elbows
  • Suited to general floor and stretching work
What to check first
  • Heavier than thin TPE travel mats
  • Single color option listed

Performance notes

NBR foam compresses more than TPE or PVC of similar thickness, which softens impact on knees and elbows during floor work. At 1.8 pounds it is heavier than the lightest travel mats, a direct tradeoff for the added cushioning.
