Review: ***** GREAT VEST for men or women - It's difficult to put the weights in the vest because the Velcro is so incredibly strong (if you don't have strong hands, it's difficult to do) I had to get to somebody to do it for me. I have tendinitis in my hands and wrists. The weights go in the vest from the bottom up - which makes a person think that the weights could fall out and break your foot. I guess this is where the strong Velcro comes in to play. I noticed throughout the descriptions and the ratings - that no one mentioned a "woman" wearing the vest. I was a tad worried that it would be too big for me, after all, the video does show a great big strong man using the vest. I'm a 68-year-old woman with loads of medical issues (pain) and I'm extremely pleased with the vest. It is very sturdy and I think it will last a lot longer than my lifetime. I'm 5.5", weigh 150 pounds and I wouldn't describe myself as strong. Once my friend installed the weights, he said, how are you going to get it on? (lol, hadn't thought of that before) ... I laid it on my bed and basically crawled my upper body into the vest. I did the same thing to take it off. The vest fits me without having to do any adjustments.. it's a tad loose, which I like! I'm carrying 11 pounds + the vest weighs 2 pounds. I wore it the first time today for 2.5 hours as I putzed around my home. It felt good. I have an atrophied rotator cuff muscle, which creates a lot of pain in the neck and shoulder region. Carrying 13 pounds and my shoulder pain was minimal. The shoulder pads are nicely padded. I highly recommend this weighted vest. I never buy anything without doing my research, and as far as I'm concerned, this is one of the best vest out there!!! I found others that I liked, but being a prime member, and getting free delivery, sealed the deal. SP Review: Great vest - I wanted to start rucking but didn't want to spend the money on the pricier brands, this works great. I'm 5'4 145 lbs. I've used up to 20 lbs in it so far, it definitely can handle more. Got some attachments for a water bottle and stuff. Oh and get the curved plates, definitely more comfortable. Shoulders can tire but I don't think you can really escape that. ## Features - Weight Plates Not Included With Purchase - UPGRADE YOUR WORKOUTS | BURN CALORIES FASTER.

SP ### ⭐⭐⭐⭐⭐ Great vest *by A***D on 28 August 2026* I wanted to start rucking but didn't want to spend the money on the pricier brands, this works great. I'm 5'4 145 lbs. I've used up to 20 lbs in it so far, it definitely can handle more. Got some attachments for a water bottle and stuff. Oh and get the curved plates, definitely more comfortable.

The quality is better than some of my more expensive carriers. It fits great and is comfortable. Would highly recommend to introduce to your workouts. ## Frequently Bought Together - POLYFIT (Fortify) Weighted Vest for Strength and Endurance Training, Rucking, Fitness Workouts, Running, WODs - POLYFIT Weight Vest Plates - Weighted Plates for Strength Training Weight Vests - 4lb, 6lb, 9lb, 14lb, 19lb Pairs - Antrix Embrace The Suck Embroidered Badge Emblem Patch Tactical Military Badge Hook and Loop Patches --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/486345422-polyfit-fortify-weighted-vest-for-strength-and-endurance-training-fitness](https://www.desertcart.jp/products/486345422-polyfit-fortify-weighted-vest-for-strength-and-endurance-training-fitness) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-12*
