Best thing I've bought all summer, especially from the recent heatwave we've experienced. Fully vented jacket that is cool when riding and not uncomfortable to wear. I sized up from my regular 44 to a 46, based on that little bit of extra room if I wanted to get a sweatshirt underneath on cooler days. Sizing was perfect and comparable to other brands (as I usually wear Dainese). I will be also purchasing the optional back protector when it's back in stock as with this, it would be the perfect all round summer jacket. The push button collar is a nice option, given that most are velcro jackets that can rub if the sizing isn't correct. The adjustable cuffs are also great as you get plenty of ventilation up the sleeves with short cuff gloves, but would be also perfect for a longer race glove if you have them. SBS we're also excellent in sourcing the jacket given it was selling out quick with the weather we've been having. I've been commuting to work most days with this new purchase and its been faultless and comfortable. Would certainly recommend.
