Quality woman’s weighted vest

I got the black 10 pound size medium vest for my partner. She says it is well fitting for a medium, with a decent amount of flexibility for differing chest size. The fabric choice is comfortable, good stitch work, the zipper is smooth and reliable. There is a full spare of elasticized bands for each side included in a drawstring branded bag.
The pockets are roomy enough to hold the essentials on a jog or walk.
Overall, it is a true to size, comfortable, well made weighted vest.

Comfortable

I’ve tried different weight vests and this one is the most comfortable due to its weight distribution. For reference, I’m female, 5’6” and about 145lbs. I’m wearing the size medium (10lb) vest. The zipper is easy to zip and hasn’t given me any problems yet. I like the 2 front pockets. They are small but adequate to hold things like keys or small objects. My only minor issue is the excess draw strings. After adjusting to your body size, the strings kind of just dangle at the sides. Also, the price might be a bit high for some.

Good weighted vest for strength gains

Highly recommended for walking, rucking, bodyweight workouts, and gradual strength gains. Good quality material and the straps on the side allow you to snug it up or loosen for a good snug fit. Start with 10lb, progress slowly. Excellent entry-level vest; beats sand-filled competitors in comfort and consistency. No smell.

Quality Weighted Vest, Can Adjust The Weight, Good For The Ladies

I was drawn to this vest as a female with a large chest. The adjustable cords on each side means you can control how tightly it fits. It is contoured in the chest area and is much more comfortable than the other vest I have. The vest and the weights are flexible and they have thoughtfully included zippered pockets to stash your phone, keys or money in and a reflective stripe to keep you safe if you're out in the dark. The weights are easy to remove and reinsert and can be used to adjust the overall weight of the vest by simply using some or all of them. The vest is washable to keep it clean and fresh between workouts and came out fine after washing in cold and air drying. The zippers operate smoothly and feel like they are good quality. It is priced at $139.99, which while it seems a lot, is in line for a quality weighted vest.

Actually comfortable to wear/highly adjustable/NO funky smells

I ordered this weighted vest to wear while I am home, outside on walks, and while on the treadmill. Weighted vests are a great option to help muscle tone and challenge your body/metabolism in a gentle way. This is my second weighted vest and this one is SO MUCH BETTER than my other one.

What makes it better?
* NO funky chemical smells out of the box or while wearing
* ability to change out/store weights (I love the storage bag that is included for the weights)
* ability to adjust the fit with the size bungee chords (so this works for multiple people to wear)
* ability to wash and air dry this without sacrificing the form/function of the product
* It doesn’t dig into or put pressure on my shoulders or mid section like my other vest/the weight is distributed well
* nice zipper quality, comes with extra bungee, has zipper pockets to store small things
* good reflective striping and reflective logo by shoulders/neck. Nice for low light use

This has been a very durable and hardworking vest for me. The fit is wonderful and it makes it comfortable enough to wear all day if I so choose. All these factors make it worth it for me to spend the extra money compared to other lower quality/priced vest options. The value for the money is there if you are planning on wearing/using this daily.

This is an easy 5 stars
