After extended use of this adjustable weighted vest, it remains a highly effective tool for enhancing endurance, strength, and overall workout intensity. However, one notable consideration for long-term wear is shoulder discomfort. Key Observations: ✔ Effective for Shorter Workouts – This vest performs exceptionally well for high-intensity training, such as sprinting, calisthenics, and bodyweight exercises. The adjustable weight system allows for versatility in resistance training. ✔ Good for Hiking & Rucking – While beneficial for outdoor activities, prolonged wear may cause noticeable shoulder fatigue due to the pressure of the added weight. ⚠ Shoulder Strain Over Time – Extended use, especially with heavier loads, can lead to discomfort in the shoulders and upper traps. Adjusting the straps can help distribute the weight more evenly, but prolonged wear will still exert pressure on these areas. Best Use Cases: • Short-to-medium duration workouts (30–60 minutes) • Strength and endurance training • Weighted hikes or rucking (with mindful breaks to prevent excessive strain) Final Verdict: This vest remains a high-quality, effective training tool, particularly for short-duration, high-intensity sessions. However, for longer workouts, users should be mindful of potential shoulder fatigue and consider adjusting the load accordingly.

40 pounds, Easy to lighten, well-made sandbags, a vest that will last a long time. Just be careful not to toss it around carelessly, lay it flat or hang it on a sturdy hanger. I'm happy with my purchase, although the shoulder straps aren't very padded, and I spent another $9 to buy two thicker ones.

I wear this RunMax pro 40 ib vest mainly when I hike up mountains and go bike riding. First thing I want to mention is putting this on really adjusts your posture to a very natural position. I have had minimal pain wearing this, even when hiking long distances. No pain in shoulders or lower back as of yet. It might help if you use your phone or a mirror to properly strap this vest on and adjust as necessary. If you do so, you might not need to buy the non-including shoulder straps they sell for this. I think it's so well designed that it really isn't necessary, but experiences do vary, and I suggest just adjusting it slightly as needed, but just getting the straps across as straight as possible should do it. I will say, despite it's apparent simplistic aesthetic, I think the design of this vest itself is excellent for usage. The quality overall is very good, but I have noticed that maybe after the 4th hike the velcro straps did start to wear out, but I suppose that's to be expected with 40ibs of T A C T I C A L S U P E R I O R I T Y bouncing all about. Well, it's not quite tactical as it could use more pockets. However, you do have a front pocket that'll hold your precious livelihood (yes, your cell phone) there's a metal ring I use for my keys, and even a whole water bottle holster to arm yourself to the teeth with liquid rehydration. ...Yeah... Well, there's not much to say about this vest really. It's relatively comfortable, it doesn't feel too constraining or put you at risk of overheating due to it's very airy design... Somehow, despite the RunMax name, I'm not sure this is the most aerodynamic of designs 🤔 but I digress. This vest does have the option to remove sandbags so I suppose you COULD have "added storage" for the removal of weight, but I'm just not sure what you'd be putting in those kinds of pouches aside from the occasional candy/granola bar 😳 In all seriousness this vest is great, even despite it's very basic exterior. Compared to other vests, it's comfortable for many different sizes, you have lowered risk of overheating, lowered risk of pain and it's adjustable to your needs as you become a chiseled masterpiece overtime. If it ever did just have more pockets, this would be quite sublime. If you need, you can consider buying a drawstring backpack, and items with very appealing names such as "wAtEr bLaDdEr" and "fAnNy pAcK" to keep you hydrated AND storage friendly. And maybe some sort of solar external battery (that's right I just called you out again!) And I'm not saying anything about anything, but in a pinch, if in case of a pesky zombie apocalypse this thing IS still 40 ibs. You do the math... What are you waiting for? For 50 bucks go get those glutes in shape err get your butt in gear

Bulkier than I expected. Fits fairly comfortably, however lots of impact/bouncing is a lot on the shoulders. Love it for weighted walks and runs, definitely a workout.

The weight vest arrived packaged well and as described. The vest is as comfortable as you would expect. If you have thinner shoulder/lat areas you may want to opt for the extra padding. If you have some muscle up there the vest is fine the way it is. I used it on a couple of 3 mile outings with no shoulder marks, with only a t shirt underneath it. What I really like is the vest has 5 weight pouches up front and in the rear. I believe each pouch is 4 pounds. So you can easily adjust the weight and maintain the correct balance very easily for different workouts. Another nice feature is that the weights (soft heavy pouches, loose material sand?) are held in place very securely. I have had other weight vests that while putting them on weights would fall out, not this vest. The vest is warm, but that is to be expected, just dress accordingly. Overall a really well thought out and manufactured product. It also has a pouch in the front to hold your phone or other smart devices, music etc.

For the money you can't go wrong. Really nice quality. Everything is heavy duty stitching and fabric. Weight bags slide in and out real easy. I don't wear a shirt under and no irritation so far. Use for indoor activities at home. Couldn't get heart over 100 anymore this did the trick. Now I had muriatic acid spill in my Work van a few years ago. Don't have a sense of smell so can't comment on that one. If you tighten straps correctly does not seem to move at all. Has pockets in the chest. And a water bottle holder. Like store 16.9 bottle. Was worried about the head hole but not an issue. Don't even need to take ear buds out. Pretty easy and I got a big dome. Now only con for me is your not going to get any air circulation at all. So plan on wiping it down after each use. Otherwise awesome.
