Alex, you are a gentleman. Thanks for looking.
The splash top is not quite what I am looking for; would it be worth a trip to have a look? There are both Musto and HL shops in Lymington (where else!) but the prices are through the roof. The HL place wanted £480 for their Ocean Pro Dry Top smock. OK it comes with neck and wrist seals, but.......
HL have the red offshore looking smocks with yellow hoods for £130 and they are Gore-Tex. it's always best to ring before you travel as they may not have your size.
If you need me to pick something up for you just let me know
