Review: I will buy again in the future - My son has been swimming for awhile, but just switched to this type of swim trunk because he needs them to wear under a wetsuit. He wasn't sure about them when he first tried them on because he was so used to the standard baggy style. After swimming in them the first time, he was a convert. He made the comment that "they don't ever seem to be wet". From toweling off beside the pool to 5 minutes later in the locker room, they were almost completely dry. He said he was surprised at how dry they were compared to how his baggy ones are always soaking when he was putting them into his swim bag. These are now his go-to trunks for swim practice. I cannot yet speak to durability since we've only had them a short time, but so far they are just what we were looking for. Fit well under his wet suit. Drawstring is extra help to prevent accidental overexposure. Nice sturdy, opaque fabric. Arrived in a timely manner. I'll buy another pair for the season to alternate daily. I'll also look to buy these again when he grows into the next size. Speaking of size, I followed the other (very helpful) reviews and bought the 26 (he's an 8/10 in the waist in boys pants), which was a perfect fit with a little bit of room to grow, so they should last him for awhile.The manufacturers tag attached to the shorts shows the following size guide for boys/men, which seems to correlate well with standard boys' clothing sizing: Us Size TYR size Waist in inches 4/5 22 22 6/7 24 24 8/10 26 XXS 26 12/14 28 XS 28 16/18 30 S 30 - 32 M 32 - 34 L 34 - 36 XL 36 - 38 XXL 38 - 40 XXL 40
Review: True to size, color hasn't faded after a month ** Update July 2019 ** - ** Update July 2019: My son has now worn these for 10 months, 3x a week, as well as at several competitions since my initial review in Oct. I haven't noticed any fading in the color, and the material is holding up well. No tears or rips in the seam despite regular use and weekly laundry. But most amazingly, the color is as solid and uniformly dark navy as it was the day we got it. The chlorine has had no effect on the color or durability of the material. They need to make swim caps out of this stuff. Those silicone caps are no match for 10 yr old boys. ** These are very well made and perfect for my son on the swim team. The material is thick and durable, and I haven't noticed any fading of the color over the past month despite constant exposure to chlorinated pool water (he swims 3x/week, 50 minutes a session). The TYR logo is embroidered onto the jammer so there's no peeling or cracking of a glued on logo. We ordered size 26 as his waist measured 26 inches, and the shorts were a good snug fit. There's definitely room to grow. I suspect that this will easily fit him until his waist is over 28 inches... giving him plenty of space to fill out. There was no mention of this on the listing, but the jammers come with drawstring ties for the waist.

### ⭐⭐⭐⭐ Summer swim team

Suit fit as expected and has lasted for the duration of summer swim league. There has been a little scratching/pulling on the rear end despite my son being careful about not sitting on concrete in them
