The NORDCODE Pulse blue is a beautiful lightweight Polyester jacket, but you can't really call it "summer". It's quite warm for summer. Maybe for a summer evening. But for a hot and sunny day, you can't wear it at all! You will sweat. You will get soaked! It doesn't have vents for air circulation and cooling like the Nordcode Aero-R II, which is a truly summer jacket. The Pulse is more of a lightweight 2.5-season jacket, i.e. for spring, autumn, and mild winter when it's not too cold and when it's not raining (it's not waterproof). It has internal protectors for shoulders, elbows, and back. It has 4 external pockets with zippers, but they are not very spacious. It has one internal pocket that closes with Velcro (no zipper) and another smaller one for a mobile phone, which also closes with Velcro. It has plastic (not fabric) Velcro straps on the wrists and an adjustable drawstring at the bottom. You can wear it off the bike for a walk or a stroll.
