Question: What are the dimensions of the vest?  Height by width when not on a person?
Document: They need to have a real XL-  I wear a size 46/48 jacket and this thing barely fits on- looks like a weird reflective Bra. I am not talking about height- it comes down to about the stomach area, which is by design-  this is width- ability to wrap around and fasten to bigger objects. Apparently the message they are sending is that either bigger people shouldn't try to run (how do I get smaller then?) or that fat people should get hit by trucks in the dark as part of natural selection.
The vest does everything it's supposed to. Which is... be bright in the dark. Used this for running the Ragnar relay, as did many other runners in the race, and at 2am in pitch blackness, I was able to see people long distances ahead who were wearing this.the only problem I can see with it, is that for someone my height (6'2&#34;) It's incredibly short.
i am a runner. i am a small person. sometimes i have to wear reflective gear for night runs. i hate borrowing other people's reflective vests because they are super uncomfortable and fall off. this vest fits and also reflects light so maybe you won't get hurt or die.
Take that into consideration. To see the actual color brightness, go to your local running store and take a look at the vest in person.The vest looks kind of dorky, but it excels in the department of visibility. I'm fine with that if that reduces the chances of a car plowing into me.
Vest was smaller than I expected, does adjust with Velcro at the bottom. Picture on package shows that it is not intended to reach your waist, more like bottom of your ribcage. Would not fit well over bulky sweatshirts for an average sized person (5 ft 7, 150 lbs).
Review seems a little smaller as large as your order.Height 179 weight 80 is Pointed.May be too small for those of you who are of a larger physique.
I've used this for a few years now. First bought for a Ragnar overnight relay. I do a lot of my running in the early morning before sunrise and this vest has done the job. I'm a small person (5'3" and about 95 lbs) so the only thing I don't like about the vest is that it is loose on the bottom - but it would be a bit loose for the average sized female runner, too, I think. The velcro only allows you to tighten it so far, so it does sway a bit as you run.
Have only been using it for about a month. Some reviewers complained about the short height, but the light weight and short height make you forget you are wearing it. The only issue I have is that this same light weight and short height let the velcro tabs on the sides have a mind of their own, sometimes twisting and other times just grabbing onto anything nearby. Hey, it's an extra few seconds or so chasing these tabs versus wearing one of the larger sandwich board type vests. I'll stick with this for running, thank you.
I purchased the large/ex large after reading reviews saying that it ran a little smaller than anticipated. So it was a bit too too wide. I'm 5'10", and weigh about 145. It hits right at bottom of my rib cage, which on a tall body frame looks weird. It is way too wide. Because of how wide it was, it made running a little uncomfortable,and wouldn't stay in place and you are unable to adjust the width. My advice is pay attention to sizing. I hope this helps.
This vest is very lightweight and adjustable. I do wish it had a few places to clip on lights though.
