Wear it How You Want

With pulleys designed to double the pulling force, you can easily pull them together to adjust the tightness to your liking. The more you pull, the more tensional force you experience.

Tighter? Looser? Up to you.

The comfy adjustment strap lets you freely control the tightness of the belt. With strings that have been tested for over 330lb(150kg) of pressure, you'll know you’re in good hands (or strings) when you tighten these around yourself.

★★★★★

You can snug up the belt easily, and it holds your back very firmly. When your lower back pain is intense and you don't have the strength to pull, there are times when using any other lumbar belt is challenging, but the Guardner belt makes this very possible.

I work as a caregiver, and most of my duties involve either sitting or standing, with a majority of the time spent in half-waisted postures. It becomes problematic if there's pressure on my hip joint when I shift or squat, but this product helps me maintain stability without experiencing any uncomfortable pressure or shifting. However, I don't believe it's suitable for individuals who prefer not to draw attention to the fact that they're wearing it.

I wear this belt daily for quick hip stretching, comfort, and improved posture. Despite initial concerns about muscle weakening, it's reassured by experts. Its versatile design allows comfortable positioning on the waist, back, or hips. Although initially uncomfortable, I quickly adapted. I wear it daily during my commute or at home and highly recommend it.

I'm in my 40s and a parent to elementary and middle school students. When there's a school event, I walk for about 40 minutes back and forth, and I used to feel really exhausted afterward. Initially, I thought it was due to a lack of exercise. However, when I walked the same route while wearing this Gardner belt, I wasn't tired at all! I've noticed that I can walk faster than usual when wearing this belt.

I bought this belt because I saw it often on Instagram, and I was curious about it. The moment I put it on, I felt my posture improve, and walking became easy! It can be a bit tight for an extended period, but it might be a good idea to use it when you feel like it

 FAQ 

How do I measure myself and choose the size that fits me right?

The best practice is to measure your waist with a shirt and decide which fits you, and if you're unsure, go with a size above what you measure. Then, wear it halfway over your pelvis.If using it for multiple reasons, match your size with the chart. If unsure, choose one size larger. Sizes available: S (73 cm/~29 inches), M (83 cm/~33 inches), L (96 cm/~38 inches), XL (115 cm/~45 inches). Share with loved ones and friends of similar size.

Is the belt machine washable?

You can. Simply fold the belt, put it into the laundry net, and put it on a soft wash. If you don’t use the net, it might cause damage to your clothing. It’s also recommended to dry indoors to prevent color fading. 

How durable is the belt? Can the line be cut?

It depends on how much you use it. But it has been tested in Japan and withstood a 331lb pull test without a hitch. Even after 441lbs were applied, the line still held intact. But the line itself can be cut if you’re carrying sharp objects or leave it open for domestic animals to take a munching to. 

Does the belt come with a guarantee that if it’s damaged it can be repaired?

If the belt you get is defective, we’ll send you replacement parts free of charge. In some cases, we’ll even replace the belt with a new one.

The strings do have a warranty of up to 3 years. If anything happens in that time frame, we’ll send you a fresh set of strings free of charge. In the unlikely chance that the strings break, please shoot us an email at info@guardner.jp. Though the product (besides the strings) doesn’t come with a warranty, we do sell replacement parts. Also, please keep your order number on hand and be sure that the “Guardner” logo stays on the belt so we know it’s ours.
