Review: Durable Swim Jammers That Handle Serious Distance - I put these TYR jammers through serious testing this summer - over 100 km of swimming in Lake Michigan - and they held up incredibly well with no issues. The Durafast One material lives up to its name; after all that distance and exposure to sun and water, they show no signs of fading or wear. They feel great on during long swims, providing good compression without being too tight or restrictive. The fit stays secure without riding up, and the adjustable drawcord keeps everything in place. The 4-way stretch is comfortable and allows full range of motion, which is crucial for longer distance swimming. They dry quickly after getting out of the water, and the 50+ sun protection is a nice bonus for outdoor swimming. For the durability and performance you get, these are excellent value. Review: Great for swimming laps - These are great jammers, I've had these for about a year, and I swim laps pretty regularly, probably average twice a week. These things have held up really well. I've been swimming regularly for a few years and this was my first pair of this type swim suit. This TYR jammer fits me amazingly well. I've read reviews on all these type swim suits, that they can be tight just above the knee, yeah maybe, but you either get used to it, or it loosens up, or its not really that tight. The liner inside works well as far as keeping things up front positioned, and the stitching seems strong, like you don't have to worry about the seams splitting like in the butt area. The draw string works well, not that you really have to use it that much, but its some added security I guess. These are so much better then swimming laps in board shorts or even shorter standard type swim trunks, you definitely notice the difference as far as gliding thru the water, What else; the color has held up (I got black), it has not faded much considering all the chlorine in the pool water. As far as size goes, I was confused with reviews saying order a size larger then you are. I ordered my waist size and they fit fine. One thing, I'm not sure if this type swim suit comes with a small pocket to store a lock key, that might be nice, but I realize these are made for competition/speed so maybe they don't make them with that option. I will buy these again in the future. ## Features - 100% Polyester - Imported - DURABLE and SLEEK: designed for today’s athlete, long-lasting swimsuit built to withstand the rigors of chlorine while providing swimmers and performance athletes with unrestricted mobility - FIT: above the knee, compression fit with adjustable drawcord waist.

I've read that some Jammers are so thin that "nothing is left to the imagination". I was hoping these are relatively discreet** A: No, you can't see through them at all. But the jammers are tight. **Q: Having trouble figuring out sizes. my son is 11, 55 in tall wt approx 90 lb. Thoughts?** A: The sizing is by waist size. Your best fit will be measuring his waist and ordering the nearest size. My 11 yr old is 85 lbs and very lean and wears a 28. **Q: Does this item have a jock suport sewn in? Tried others that don't, and it looks like a camel toe.** A: No I can’t say I’ve ever seen a men’s swim suit with jock support sewn in. **Q: Do these fade?** A: My husband has been wearing these (this brand) for years and he said "They are awesome and no they never fade!" ## Customer Reviews ### ⭐⭐⭐⭐⭐ Durable Swim Jammers That Handle Serious Distance *by T***M on November 4, 2025* I put these TYR jammers through serious testing this summer - over 100 km of swimming in Lake Michigan - and they held up incredibly well with no issues.

At the time I purchased the Speedo, I wore a size 38 waist, and so I purchased one size down because in the past, I've found that one size down from my pant size usually works for competition suits. In the four months that I used that suit, I dropped down to a 36, and so when it came time for a new one, I figured 34 ought to be the right size. In retrospect, I should have purchased the 36 for the TYR brand. What I love about this suit: The material is a polyester blend which holds its form and color very well. The material also dries very quickly, and this is important because putting on a wet suit is a pretty awful feeling. The suit is tight enough to keep my business in place without being restrictive. When I get out of the pool, the suit doesn't suck up against my man bits to reveal a profile of what I've got going on, even after it's broken in. What I don't love about this suit: The waist is a bit tight, but I have myself to blame for this problem. The closure on the thighs are very tight at first almost to the extent that I would have to cut my workout short to avoid a complete cutoff of circulation, but this ameliorates over time. Even swimmers with smaller waists than mine could have more muscle mass in their thighs, and this makes the design problematic. For this design flaw, I drop one star. How it measures up against Speedo's Endurance Race +: I would give Speedo the nod overall, but not by much. When I purchased my Speedo, it was less expensive than it was when I bought this TYR. I would feel comfortable buying either again, and cost will be the sole factor in making that decision. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/1566759-sandblasted-jammer-swimsuit](https://www.desertcart.jp/products/1566759-sandblasted-jammer-swimsuit) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-09*
