STEP 1: Measure the length.

Measure the length of the dressing please allow extra for the seal either end.

STEP 2: Measure the circumference for a watertight seal.

Measure the distance around the leg above (A) and below (B) the cast or dressing.

STEP 3: Check the size chart.

Based on the knee sizing chart, choose the Bloccs® cover that will fully fit over the cast or dressing whilst still forming a tight seal.

Note: Always measure for a watertight fit.

Size is determined by the seal size not the length. The larger size knee
protectors have larger seals around the leg and are shorter in length.
