So NIce They Were Stolen!
I recently bought the Speedo Men's Swimsuit Jammer in Endurance+, and let me tell you, they are fantastic! The fit is perfect, and they provide great support and coverage without feeling restrictive. Pros: Comfortable Fit: These jammers fit like a glove! The material is stretchy yet supportive, allowing for a full range of motion while swimming. Durable: The Endurance+ fabric is incredibly resilient against chlorine, which is essential for frequent swimmers like me. They look brand new even after several sessions at the pool. Stylish Design: I love the sleek design—these jammers look good on! I’ve received several compliments while wearing them. Cons: Price Point: They are a bit on the pricey side, but I believe the quality justifies the cost. Overall: I loved these jammers so much that I’m pretty sure they were stolen from the aquatic center! I had to buy another pair because they are just that good. Highly recommend them for anyone looking for quality swimwear!

Would buy again best I have had
Best Swim Trunks I’ve Ever Had I swim a mile every day in the pool and wear the same pair of trunks each time. Normally, after a few weeks, they’re so worn out you can practically see through the backside. Not with these! After five months, they’re still going strong and look like new. I rinse and dry them daily, and occasionally throw them in the wash. They do run a bit tight—I’m a big guy—so next time I’ll size up. But overall, these are hands-down the best swim trunks I’ve ever owned. Definitely buying more! Edit: May 18th 2025. Still going strong in the look almost new

Pretty durable; sizing is complicated
I bought these because I started swimming laps for cardio improvement. I'm 5' 11" and at the time of purchase, weighed 165 and wore waist size 33 jeans. I am thin but have a little muffin top because I am out of shape and only recently started exercising again. I was concerned about the mixed messages regarding sizing. According to Speedo's sizing chart, having a size 32 waist means that you're supposed to buy a size 30 but reviews suggested to buy the size corresponding to your pants size. Being a size 33, I bought both the 32 and 34 with Amazon's try before you buy program. I acknowledge that the proper fit is supposed to be skin tight and completely free of wrinkles but never having used anything but "swimming trunks", I felt more at ease with the size 34. The more appropriate fit for serious swimming would probably be the 32 or 30 but I felt uncomfortably exposed with the size 32 and I can't and don't want to imagine wearing a size 30. The inner lining is made of the same material as the rest of the jammers and smooths out the front panel to the extent that my children don't cringe. My old swimming trunks were Columbia water shorts and made of polyester so they held up but bleached out after about 2 months of 5 days/week 1 hr lap sessions. These Speedo Endurance jammers are holding up well after 4 months of comparable usage with only the stitching starting to fade out. As a comparison, my childrens' spandex/nylon swimsuits literally disintegrated in the same time frame. The best part is that I cut 2-3 strokes per 25m length just by switching to the jammers. On average, that savings comes out to ~195 strokes per 66 length mile. So for my swimming style, I'm saving about 9 lengths/mile just by using these jammers. Lacking experience, I had no idea that there would be such a difference. I'm gliding in the water and not dragging as if I'm pulling a parachute like with my old trunks. Now, after 6 months of steadily working out and swimming I'm replacing fat with muscle but I'm losing more fat bulk faster than adding muscle bulk. So I've dropped 10 lbs, my muffin top and I cinch up another belt notch on my size 33 jeans. The 34 jammers are now loose and the extra material leaves wrinkles in the front and clings when wet. I kept the 32 jammers and these now fit comfortably and I plan to use them until I can put some good weight back on. Long story short; I like and recommend the Speedo Endurance Jammers and would buy them again. They last longer than standard swim suits and significantly reduce drag. Took off one star because the stitching will eventually fail first and they should have used the same material for the stitching as for the rest of the suit. Hopefully, my sizing experience will help make informed decisions.

Quality materials are a much better value than cheaper competition.
Go with this great material, and perfect length and fit., rather than settling for cheaper but less durable suits. I swim a mile 3-4 times a week, and other suits wear out quickly.

Durable, Comfortable, Fit as Desired
These suits are great. There's a small internal lining in the front which helps keep things in place. The seam down the front is not super noticeable and the overall build of the suit is flattering. The internal drawstring works well and isn't too short. I'm 6'1", lean athletic build, 200lbs and the size 34 fit perfectly. It should compress a bit if you're serious about swimming. The black color is good, and I've only swam with this suit a few times, but so far I see no evidence of fading or stress on the seams. The "Speedo" logo is embroidered which is a nice touch as the suit maintains a good look.

Too tight
Good quality and nice thick fabric, but they weren't big enough in the butt or the leg openings, which make them uncomfortable. I'm 5'8" 180lbs athletic build and bought size 32.
