"Brilliant!"
Bought these five years ago when I was sailing Transatlantic and they were brilliant! All my clothes stayed dry and I could reduce them to barely anything at all with the air squeezed out which is important when storage on your yacht's at a premium! They did me proud for three crossings and time spent in the Carribean and though I'm land-based now I still have the bags and use them for holidays, they were a great investment.
