It’s wind resistant rather than windproof with the pay-off being better breathability than a fully windproof fabric. The thin lining means that it’s around a light baselayer’s worth of extra warmth compared to a single-layer equivalent. Whether than makes it too warm for bike use is probably down to how cool or warm you run, I find it good in temperatures around 8?C or lower.
One of the the other pluses of it being relatively breathable is that you can layer it, for walking or mountaineering, under a waterproof if you need to. It only has a little water resistance after a bit of use and repeated washing anyway.
I’ve had mine for around three years now and it’s been deceptively durable. There’s pilling under shoulder strap and hip-belt areas, but while it looks messy the fabric hasn’t worn through despite being pretty light.
Mine’s a VR Lite Alpine and the wiring in the hood has a sharp bend in it now and it feels like it’ll break there eventually. Close fitting hood that you can, in really nasty conditions, layer under a helmet.
If you want something more breathable, the VR Flex has very permeable side panels, so doesn’t run as warm. Then again it’s a little less protective and doesn’t have a hood.
Overall it’s a great bit of kit, surprisingly durable and definitely not ‘too nice’ 😉 to wear on bike unless you’re some sort of fashion tart…
