Review on Proviz Reflect360: Boost Visibility with High Viz Reflective Resistance by Chris Hayes

Great backpack for cyclists (as expected): spacious, with a large pocket and a pocket for quick access to "little things" directly on the back. There are mesh pockets on the sides, big enough for gloves, headphones, a tire repair kit, a small pump, etc. I use it for cycling with a pair of shoes, pants, a shirt, a belt, sometimes with a jacket, etc. and it is still room for more stuff (if you're so inclined). Two complaints, one big and one small. One small complaint: the chest and waist straps are pretty flimsy. They work, but seem rather irrelevant. Big Complaint: The back of this backpack has no ventilation and gets very hot on the back. You'll find that even on cold days, sweat drips off your back. It's like driving with a thick blanket on your back.
