I am located in the UK. I first tried the UK distributor Oceanic and got no reply from them, I then came accross a website for Hollis UK and again no reply. I then sent 3 or 4 messages via the online form at the .com main Hollis site and again no reply at all. Eventually I did call Hollis in the US and was told It's nothiong to do with them as I purchased in the UK
I have been told since that the Hollis dx300 drysuit wich I had a problem with is only available via Oceanic in the UK and is manufactured in China, they just use the Hollis badge and logo and Hollis in the US despite putting their name on it don't want anything to do with aftersales.
The suit is an absolute load of rubbish, the seals split when just trying it on and overall the suit was of poor quality. The most annoying thing is that the dealers know there are problems but they just keep selling them.
