I had an Aqualite for a few years. (not the Extreme, and I’m not sure how they differ) Anyway……. The Aqualite was ok, but not great. Pack size is it’s major plus point, packs down small almost like a Pertex and it was reasonably waterproof. Breathability was poor, got sweaty very quickly – it won’t stack up against your Gill Event. It’s a very basic jacket, no pockets, no fleecey collar, just elastic at waist and cuffs. Cut is cycling specific and works alright, sizing is on the snug side. I had to go up one size from what I’d usually expect to be. :-)
