    • Helps with Sciatic Pain and Swelling- Finally Some Relief!!
Color: Beige Size: M/L(Waist:28"-31")
I am 5'6" female, 167lbs, and I have been dealing with sciatic nerve pain, tension, and lower body swelling for months. This brace has honestly been a lifesaver. It gives me the right amount of compression and support to get through the day, especially when the pain flares up during work or when I've been on my feet to long. I took everyone's advice and sized up to a large, and I'm so glad I did- it fits just right without feeling too tight or restrictive. It's also very adjustable and comfortable to wear, even under clothes. It stays in place and doesn't dig in, which is a huge plus. When I wear it regularly, I've notices less swelling, better posture, and a real decrease in daily discomfort. It's not a miracle cure, but it definitely helps. I still stretch, rest, and follow PT routine but this brace adds the extra layer of support I really needed. Highly recommend is you're struggling with sciatica, swelling, or lower back tension. ... show more

Color: Light Beige Size: S/M(Waist:26"-28")
Unfortunately I ordered the wrong size. I will say it looks well made and looks comfortable. Not bulky.

It isn’t the support I need. Will be returning it. It didn’t fit either. I went by there measurements, so was surprised it was 2 small.

    • SERIOUSLY, JUST BUY IT! GETTING ANOTHER!
Color: Beige Size: L/XL(Waist:31"-36")
I'm a therapist so I'm very picky about things like this. I find most back braces "overdo" and are so bulky they add a new level of discomfort. It's like "my back feels a little better, but this brace weighs a ton and is hitting my lungs when I sit down." I am having an SI joint issue, and I went looking for a lightweight and simple design. This was one of two that looked good, and the price here was great. So I ordered without expecting much. It just arrived and seems very well made. I went to put it on, and made sure to place it low enough to be directly over sacrum (since mine isn't lumbar pain currently). I immediately felt incredibly relieved. I walked around with ALL pain gone, and when getting up from seated, which is the worst with this, it's about 60% reduced now. If you know sacroiliac joint pain, you know that's a big deal. I'm going to order one in the next size up, because they run a little small. My waist is 34" which is average for women my age, and I weigh 132. So a large does fit me, but not quite as generously as I prefer. Still, at this great price, I can get 10 more if I want! Highly recommend, get it while you can!!! ... show more

    • Superb Design
Color: Beige Size: M/L(Waist:28"-31")
Superb Design! I have several styles of back braces, due to my compressed disc. THIS is what I've been looking for all along. It's THIN and is almost invisible under my clothes AND the bonus feature is It's COMFORTABLE SITTING ... while most brands are effective for giving me the support I require, many are too bulky when seated!!! As I'm writing this review, I'm seated and SO RELAXED! This will be my number 1 GoTo when I go out and travel. What a fantastic design! I could not be more grateful. ... show more
