UPDATE: As you can see from below description, a couple of the seams in the vest started to unravel with just 15 or so uses. However, I contacted the seller, and they sent me a replacement vest which seems to be holding up pretty well. As a result, I have updated my review to reflect: a responsive seller who stands by its product; a well-built and solid vest, with well-designed weight pockets that should last a long time. I can recommend this vest now. Aside from the initial quality control issues/problems I experienced, I think it's still the best weight vest I can find for a reasonable price. Original writeup is below; downgrade to one star due to the following: I used it only about 15 times and using only 30 lbs of the maximum 40 lbs capacity, and you can see from the attached pictures that the vest is already starting to fall apart. I've only used it for walking on my treadmill indoors, and you can see that it just doesn't seem to be very well made. I am writing the seller/manufacturer and will update this based on their response. If it's not favorable, my one star downgrade remains. Hopefully they'll do the right thing since I only bought it four months ago and it's received very light usage. In the mean time I DO NOT recommend it. OK, got that off my chest. I'll be 61 years old soon, hence, a senior citizen, AKA "an old man" as my daughters sometimes call me. I bought the vest to round out the equipment I have in my home gym. I wanted something I could adjust the weight on, and wear while working in my yard, around the house, or walking on my treadmill. Some say this chafes, but it really doesn't. Not if you wear a shirt. Of course it'll chafe if you wear it bare against your skin because it is solidly built, with very good seams, and heavy duty quality materials. The weights that came with it (I got the 40 pound vest) where all in the box, and they fit PERFECTLY into the various pockets for them. So this tells me two things: 1. The manufacturing tolerances for both the vest and the individual weight packs are precise, and demonstrative of good quality construction; and, 2. It's going to take a little bit of patience and care when you're putting the weights in. Taking them out is no problem. And putting them in is no problem either if you follow this advice: Start by putting the ones at the front and/or back bottom row in first while you're holding up the vest with one hand, or propped up against something; then move on to putting weights in the top row of the vest. This makes it so much easier and makes the job quick. It doesn't smell. But since I wear a cotton shirt underneath it while I'm working out, I think eventually some of the sweat may work it's way into the vest, at which point a light hand soaking/wash may be recommended. But this is normal for anything that comes into contact with the human body. It's a great buy and fits perfectly on my 5' 7", 145 pound frame.
