Scott's team jacket is a quality lightweight weather beater if you don't mind signing autographs.
The fabric is certainly faster sweating and more stormproof than most coats of this low weight. Having got caught out a couple of times in vile weather, it will eventually succumb to the most severe storms though, and you'll be noticeably damp if you're really pushing the pace. The long arms, long tail, high collar and hood all add to weatherproofing while riding or wandering round the pits though.
To keep weight low you just get the one stormflapped rear pocket, but it's big enough to swallow the jacket whole for easy stowing. The big reflective Scott logo gives a pro look too, but don't be surprised if folk are disappointed after thinking you're Nick Craig.
