The first way to wear it

The second way to wear

Attention must be paid when using life jackets:

1. No matter what kind of life jacket, all ropes must be tied as required. Don't be too lazy to tie it.

Don't take off the slipknot for convenience in the future. Be sure to tie the slipknot, and repeatedly check whether it is fastened, so as to avoid loosening due to water pressure impact.

3. Be sure to tie it tightly so that the life jacket is close to the body to avoid falling off due to water pressure impact after falling into the water.

4. Be sure to wear the side with reflective film and whistle bag outside. Reflective film is for search and rescue personnel to look for when an accident occurs. Whistling can be used to ask for help and avoid losing too much physical strength because of shouting.
