I use the vest for walking and training our bernedoodle. There are plenty of pockets to store duty bags.

The side zipper pockets are large. I put kibble in a quart size storage bag in the right zip pocket, attached inside at top of bag with 5 safety pins so I can reach in easily. I keep a ball and the leash in the left zip pocket when we are at the bark park.

The website recommended a size up. I am slim and stayed with my regular size which is medium. It hangs well and does not bind at arms and shoulders. It is a little looser than I prefer around the belly and waste, but it is perfect for the activity I use it for.

Initially, I fumbled with the lefty front zipper but adapted...and now have a bit more appreciation for my left-handed friends.

Compared to the expensive vests marketed in birding magazines, this is a tremendous value. Looks very nice (khaki) and appears to be well made. More pockets than you will know what to do with (and complicates finding things). If you fill them up and carry a field guide and camera, the vest (like any) will feel heavy hanging from your shoulders and banging into your body. On the other hand, all those things crammed into cargo pockets on pants and shirts are heavy and awkward too. So the trick is to distribute the weight.

Even with the open mesh fabric, gonna make you a little warmer in the summer time, Hip pockets are large enough to hold standard sized field guides or a small (up to 8") tablet computer stored on it's side. I keep it stocked with a notepad, pen, field guide, and few small essentials (lens wipes, chap stick, tissues) and it is ready to go birding without a big production. However, if you are going to be away from a car for a while you may need to carry a water bottle and a rain jacket, in which case you are back to using a day pack.

As noted by others, zipper pull is on the left / lady style. A water bottle specific holder would be a nice modification. You can carry a water bottle in an open hip pocket but it would project up out of the pocket and could easily fall out. On the other hand,t a full water bottle would add a lot of weight. Another helpful modification would be some kind of synch or belt so that it could be made to fit more snugly around the body to keep it from moving around when you are bending, climbing, twisting, etc. Delivery took 3 weeks.

I am 5'10", 155 lbs athletic built male. large is loose over a shirt, but not so much as to be a problem. Wanted to err on the large side so I could wear over a thin jacket in cooler months. On the other hand, for only another $20 you could buy a second smaller one for summer!

.

Pockets are well designed, secure, and easy to use. I wear this daily when gardening and dog walking. It is very light weight and I almost don't know I am wearing it. I can bend and work and everything stays in place. So glad I read the reviews. I am female, 5'4" and 123 pounds. I purchased the Medium which fits perfectly over a very lightweight top when zipped. Normally I would have selected a small which would have been too tight.

I wear it when walking the dogs as it holds everything I need. Zippered pockets so nothing falls out.

This runs a little bit small so you may want to get a size larger
