users should wear appropriate flotation devices with
the dry suit. Water rescue is inherently dangerous.
Users should be aware of risks associated with water
rescue and complete training in the use of water rescue
equipment and techniques.

in the industry. To order a suit that fits you best, please follow the
instructions below:
STEP 1 – MEASURING

All measurements should be taken with a ”tailors” (flexible) tape
while wearing garments and any accessories such as body armor
usually worn under the dry suit

(belt) line.

Measure the horizontal circumference around the hips
and buttock at maximum girth.

the chest, measure the distance from the center of the

the wrist.
