The idea is great: adding evenly distributed weight close to your body's core, to make it work harder without adding stress in any one place. An ergonomic advantage of this particular vest is that the thin weights lie flat against your body. It's lightweight, the cut is comfortable, and the look is almost stylish, so I don't feel too dorky wearing it for a walk in public. The shoulders are nice and wide -- also good for weight distribution -- so I haven't felt tugging or pressure there.

The disadvantages: because the weights are tallish, their tops hit my ribs in an uncomfortable place, so when I move there's friction and poking. (And I'm long-waisted, so I wonder how it fits on shorter waists.) I can slide the weights around some and move them to different pockets, but it's still a problem. The other major problem is that I have looked everywhere for additional weights (the starter kit is just that, including only four out of a possible sixteen pounds) with no success: nothing has turned up in local stores, or on Amazon, Google or the Gaiam site. The Walkvest site has been out-of-stock for weeks. So I'm stuck with four pounds, which is really frustrating. I'll be interested to see if it becomes more or less comfortable with additional weight.

One other note: I found the vest runs a bit large. I usually wear a medium or bigger, but my WalkVest medium is quite loose on me.

Advice: Before you buy, see if you can find additional weights. And since a good fit is critical, best to try on different sizes first.

Update 5/7/08: I just got an e-mail from Debbie Rocker saying the new weights won't be available for ordering from walkvest[dot]com until the middle of June. 3 stars

Vest is a lightweight cotton/canvas comfortable washable material.
Vest has refective safety strip accents.
Seems somewhat stylish although I can't explain why!!
Sides are mesh for breathability with comfortable arm holes.
Has lots of small long pockets with snaps for weights.
One large pocket on the upper back of the vest.
There are two clips on the front that are easy to adjust while walking for fit and comfort.
Sometimes I clip the clips to pull weights into body and sometimes I open them to adjust the feel of the weight- I can do this as I am walking easily.
Weights are small and sturdy are easy to arrange- they snap into pockets.
*You'll probably want more weights soon.
You'll work up a sweat without the strain of carrying weights because of the overall distribution of small weights.
I was worried about possible strain in my back but haven't noticed any difference.
Easy to use straight out of the box.
**It would be nice if it had a larger pocket for keys/phone. 5 stars

I have increased the weight of my vest to 8lbs. It is one of the best pieces of exercise equipment I have ever used. You can feel the effects of the weights on your body. I have had it for about 2 weeks, and have lost 2 inches and 5 lbs. I started with the 4lb weights that come with the walkvest and have increased to the 8lbs, today. I suggest that if you are not used to exercise you start with the 2 lbs and work your way up.

It's a lot easier then the 10lb free weights I am used to lifting. I use the dvd that comes with it and also wear it when I am walking outside or using my Gazelle air walker.

It's a great way to use weights and fight the bone loss of aging. I am 57 yrs young. 5 stars

I just purchased this vest so I cannot make a judgement on how well it works, but I was very disappointed that I purchased this vest believing that I was getting a 20 lb. vest when in fact the only weights that were included were for a total of 4 lbs. The information included in the package said you can "purchase" weights when you're ready to add more. Great. I didn't realize I had to spend even more money to get what they said was included in the purchase price anyway. Very misleading. 3 stars

The walkvest is great for making you keep good posture while walking. It is also wonderful for building strength when you are retired like I am. I especially love the MP3 player pocket. It is a little hard to get to but at least you have music while walking. I ordered the L and found it to run large. I have now ordered the S and hope it works.I have also found that my body adjusted to the 4lb weights and need extra weights, however you cannot find them on the internet to purchase.Great price for a great workout. 4 stars
