Excellent for my sea fishing son in law

He finds it very comfortable to wear and My daughter and I are more at ease knowing he is wearing it while coastal fishing

Note these will auto inflate when you wade too deep into the water and cost you £15-20 to recharge... but that is what they are supposed to do. Overall decent value for a functional product.

Re-arming kit NOT available at Decathlon

Decathlon Hong Kong does not stock the re-arming kit so this jacket is useless after one use.

Dear David,

Firstly, we apologise for the inconvenience created by our range of product.

The issue has been already passed to the production line and the production of this product is currently unavailable. 

On the other hand, we do not recommend you to reuse this life jacket as the purpose of the jacket is for immediate life-saving.

You may visit another sailing gears store to purchase another jacket which is specifically used for training. 

Thank you again for giving us this feedback and we will discuss with the production line about the related production issue.

We hope to see you again and wish you will keep supporting our product.

Please contact us should you have any further cause for concern.

Thank you so much.

Stay healthy.

How to rearm the life jacket?

Follow the order of installation instructions carefully:1. Replacing the salt bobbin2. Replacing the CO₂ cartridgeIf you do not follow this order of installation, there is a risk of hitting the new cartridge if the trigger system for the salt bobbin has been previously used.
