I first encounter the Regatta 'Isolite' waterproof jackets and trousers in a local store and was immediately impressed with their lightness and compactness. They are supplied with their own stuff sacks. I frequently carry a jacket and trousers with me in my shopping bag. Unfortunately the local store did not have my size in the jacket so I ordered an XXL size from Amazon even though there was a slight price disadvantage. The integral hood is generously cut permitting the wearing of a hat, if necessary. For example, a 'beanie' or a cap, but not a wide-brimmed hat.
What attracted me to the Regatta brand was the length (collar to hem) of the jacket. It is longer that most lightweight waterproof jackets and will totally cover a formal jacket, if one is worn underneath. I have worn shorter waterproof jackets previously only to find after a fall of rain the the hem of my formal jacket is soaking wet. Very annoying.
I have also found that the matching Isolite Regatta waterproof trousers are also generously cut. I can put them on without removing my footwear, even when I am wearing my work boots.
I cannot yet judge their durability but I can testify as to their waterproofness.
They are relatively inexpensive items of apparel so replacement is not really an issue.
