If you're looking for a jacket for gravel or bikepacking, then the Castelli Unlimited Puffy Jacket could be what you're after. Castelli say this option is ‘for when the challenge is distance rather than speed’, but that suggests you shouldn’t put any effort in lest you overheat. I’d describe it as a great ‘messing around all day’ jacket. Wearing it in winter and spring between about 3 and 12C with just a base layer underneath, you could pretty much forget about it. And that’s even in light rain, despite it only being a windproof, because it stays pretty warm when damp, and dries out super fast.
It packs down easily too – it would just about fit in a jersey pocket. The secret to most of its magic is the super-light Polartec Alpha Direct insulation, but Castelli has done a nice job of designing it into a good-looking and very usable top.
