This is the first time I've bought apparel like this and I'm blown away. It's incredibly snug and supportive yet surprisingly comfortable and unrestrictive. It even makes the upper body feel MORE agile! Can’t wait to take it for a spin.

Purchase top and pant Alpine gear, items were packed, shiped and delivered in a few days, great service & would buy again from Bike Biz.

I can’t speak for the supposed science behind it, but when taking on my first 500km interstate ride in winter (with rain😩) I stayed sufficiently warm, alert and comfortable for the duration. Next time it’s *really* cold, I’m looking forward to pairing it with my heated mid-layer.
