Our tester, Greg, described the iZip as very comfortable to wear. Adjustment was pretty straightforward using a single slider on the righthand side.

Just four seconds after hitting the water the jacket was fully inflated, with the casualty face up, making the iZip one of the fastest on test.

Once inflated the casualty’s head was kept clear of the water and Greg reported that the jacket was still comfortable to wear.

The sprayhood was a little tricky to find and get hold of but once located it was easy to put into place and offered good protection. Reflective strips were abundant, both with and without the sprayhood.

Seasafe-iZip-afterOther features include a fleece-lined collar for additional comfort and a separate zipped section for easy access to check the firing mechanism and gas bottle.

The colourful array of covers may make you think the iZip is a bit of a novelty product but that is far from true. Our casualty liked this jacket.


This was simple – just unscrew the old bottle and firing mechanism and screw in new ones. Replace the green manual fire-clip if required. Total rearming cost: £12.95


The iZip comes with a separate zipped cover and bladder. The slightly larger cover meant repacking was very easy, even with the extra material of the sprayhood to pack away. The iZip was the easiest jacket with a separate cover and bladder to repack to a high standard.
