After much research I decided upon a Pearl Izumi Pro Barrier Lite. It was my intention to get the white, almost transparent version but I couldn't steal myself enough to get anything other than the orange version.
The first thing that struck me when I got the small package containing the jacket was how light it seemed. Was the jacket even inside? I knew beforehand that the jacket had a claimed weight of just 73g but actually picking up 73g of jacket felt rather strange. It is incredibly lightweight! The material is similar perhaps to that of a parachute. It does feel quite strong despite its micro thinness.
Full length zip with a zip garage. This can be used for venting.
Elasticated hem and cuffs.
Reflective elements for low-light visibility.
Takes up virtually no room as it is very packable and can be stowed in a rear pocket with ease.
This jacket isn't going to withstand a heavy thunderstorm but if I was out and about and it started to rain, I can see its uses. Similarly if I was out and the weather was on the chilly side, this jacket would act as a great little windproof.
Recently it was voted the best lightweight cycling jacket by a well thought of cycling magazine and from my first impressions I can see why. I had it with me yesterday evening when it started to rain and it did keep me dry and warm for the two miles left I had to cycle to get home. At between £49 - £69 it isn't cheap but for me it is already worth it for that unbelievable low weight.
Tomorrow night/ Saturday morning I am going on a night ride from London to Brighton. This jacket is definitely coming with me and I am pleased that I managed to get it in time. I suspect this jacket with be with me on many a ride to come!
