Review: Our go-to brand - This is my 3rd Flow Jammer purchase for my 9 year old son who is on a swim team. These are very well constructed and fit perfectly, they hold up very well against wear and tear and fading and they stay put and are comfortable. They are a great value for the price. My son is 71 lbs, 52 inches tall and I purchased a size 26 for him. He is typically an 8-10 in pants.
Review: Great for adults. Fits well - I am an adult who swims several times a week. I usually wear Speedo jammers but tried Flow. It compares really well to the more expensive Speedo suits. Fits well. Feels fast in the water

### ⭐⭐⭐⭐⭐ Our go-to brand
*by M***N on April 13, 2021*

This is my 3rd Flow Jammer purchase for my 9 year old son who is on a swim team. These are very well constructed and fit perfectly, they hold up very well against wear and tear and fading and they stay put and are comfortable. They are a great value for the price.

### ⭐⭐⭐⭐⭐ Great for adults. Fits well
*by S***P on February 11, 2026*

I am an adult who swims several times a week. I usually wear Speedo jammers but tried Flow. It compares really well to the more expensive Speedo suits. Fits well. Feels fast in the water

### ⭐⭐⭐⭐ Sizing is inconsistent
*by A***A on February 11, 2019*

It's been a quest to get a right pair of jammers from Flow. Overall, I ordered 3 pairs of jammers in size 25, 26 and 28 (I was in a harry when ordered sizes 26 and 28 without measuring my son's waist). At first, size 26 worked fine for my son maybe just a little bit loose around the legs but on this pair (as well on the size 28) was this horizontal seam on a front V-panel as it would continue from the back - you won't find it on the pictures or in the description. I didn't like how it looked like on my son (too many seams in the front, looks funny in the crotch area), so I decided to order smaller size to get more snag fit around the leg and with the hope that I will get a pair as on the pictures. Indeed, I get a pair as advertised with just a V-panel in front but this time size 25 was actually bigger then size 26 not dramatically but still noticeable. So, now I need to return all three pair and order a size 24, I guess, because I like the fabric and quality of these jammers and want to find the right pair for my son. And thanks to Amazon for free shipping and return policy!
