Comments: Nice & lightweight but it shifts around a bit when I wear it.  I've been wearing it though over just a sports bra as it's been so warm outside so over a shirt I'm sure that it would be fine. I wish for my purposes that it was a little more fitted around the bottom (I'm 5'5" 123# and bought the SM/MD size.)  Even on the tightest velcro fitting it's still pretty loose on the sides. Cars start pulling over through when they see me a decent distance away, so I guess that's what ultimately counts!

Comments: Great vest! It fits perfectly, even though I am rather small framed (5'5", 100 lbs). With its adjustable straps, the vest fits both over just a shirt, or over a jacket, winter or rain gear. When I run on roads with some traffic, or late in the evening, the vest is an absolute must!
