Zelus’s Z-Fit Soft Iron Weight Vests instantly stand out: their features are ultra-thin, the design body-comforming, and the vests look sleek, ergonomic, and refined.
With the Z-Weighted vest, the weight is within the vest rather than outside. The vest is filled, from the straps to the back, with Z-fit Soft Iron material. The weighted material is an inherent part of the vest, in the interior layer.
But what do you stand to gain from these new vests that you wouldn't necessarily gain from traditional vests (filled with iron sand or removable weight bars)? Should you consider these vests?
Here’s the deal: while both can help increase intensity and calorie burn, the newly designed Zelus Z-Fit vests have certain particular features that make them stand out, especially if you value comfort and versatility.

Key Features of The Z-Fit Weighted Vests
1. An Ultra-Thin Design
The Z-Fit weighted vests are not just designed to be thin: they are ultra-thin. The shoulder straps, for example, are just 0.5 inches thick, significantly less thick than the traditional models.
- The ultra-thin profile makes sure the vest sits closer to your body; that way, it feels more natural and balanced when you’re walking, jogging, or doing more intense training.
- The thin nature of the vest is also crucial for the unibody design, which keeps the weight evenly distributed across your torso. The shoulder straps are wider, and the vest is wider across the back.
3. You Get Different Weight Options
Z-Fit weighted vests are not adjustable, but they come in 5 lb, 10 lb, and 15 lb versions. You can select the level that suits your current fitness, whether you are a beginner, intermediate, or professional.
- The 5 lb Z-Fit Vest is ideal for beginners who want to add a little resistance to daily walks.
- The 10 lb Z-Fit Vest works well for steady jogs or moderate workouts
- The 15 lb Z-Vest is a great fit for more intense strength and cardio sessions.
Since the weights aren’t adjustable within each vest, it’s smart to choose based on your intended activity level.
3. The Material is Comfortable and Durable
For the Z-Fit weighted vests, Zelus chose wear-resistant spandex, rather than the usual nylon-based material.
- The advantage of spandex is that it is softer against the skin and flexible enough to move with you. This makes it far more comfortable for longer sessions compared to rigid, nylon-based vests.
- On top of that, the vest is odor-resistant and hand-washable, which means you can keep it fresh even with regular use.
Comfort is a deal-breaker with weighted vests. If it rubs, chafes, or feels stiff, you’re less likely to use it consistently. With the
4. They are Adjustable For a Secure Fit
With the Z-fit weighted vest, you get a vest that is already filled to the appropriate weight, firm, and ready to use.
- The Z-Fit Weighted Vests come with an adjustable chest buckle strap and dual side straps, allowing you to customize them to your body.
- Any of these vests can easily fit chest sizes between 32.3 inches and 39.4 inches, so they are adaptable to a wide range of users.
The secure fit also helps reduce bounce and shifting: something you’ll definitely notice when running or jumping.
5. They Come with More Safety Features for Outdoor Use
The Z-Fit vests include reflective stripes on the front, back, and shoulders to keep you visible in low-light conditions. That’s a detail that many traditional weighted vests lack, but is crucial, especially if you are someone who enjoys evening walks, early morning jogs, or outdoor bootcamp workouts.

What is the Best Use for the Z-Fit Weighted Vests?
1. Walking
The 5-lb Z-Fit weighted vest is especially great to use as a weighted vest for walking.
Adding just 5–10 pounds to your frame during a brisk walk increases calorie burn, strengthens your legs, and conditions your cardiovascular system.
Because the ZELUS vest is thin and balanced, it won’t feel cumbersome or throw off your natural walking stride.
2. Running
The ZELUS vest’s streamlined design reduces bounce and evenly distributes weight, making it much more comfortable for jogs or sprints. The reflective stripes also add peace of mind if you’re training outdoors in the dark.
Running with a poorly designed vest can be a nightmare: the weight may shift, the straps might start bouncing around, and induce shoulder pressure. If you are in the market for a weighted vest for running, consider a Z-Fit Weighted Vest from Zelus.
3. Bodyweight Workouts (push-ups, pull-ups, squats)
The thin profile of these vests means you can do push-ups without the vest digging into your chest, or pull-ups without excess bulk interfering with your range of motion.
4. HIIT and Intense Training
A secure-fitting, non-bulky vest like this ensures you can train hard without constant readjustment. It stays in place, so you can focus on intensity instead of discomfort.

Why Choose This Vest Over a Traditional Weighted Vest?
- Comfort: Spandex and a thin design make it more wearable than rigid nylon or bulky designs.
- Balance: Evenly spread weight means less strain on shoulders and spine.
- Practicality: Hand-washable and odor-resistant, it’s easier to maintain.
- Mobility: Ultra-thin profile allows natural movement without restriction.
- Safety: Reflective stripes keep you visible outdoors.

It’s especially appealing for those who want to use a vest for walking, running, or versatile home workouts.
While Zelus' traditional weighted vests still have their place, especially if you want adjustable weight levels, this ZELUS vest delivers a sleek, comfortable, and practical solution for most fitness enthusiasts.
