Legit Swim Jammer - For Triathlon Training
Was a college triathlete and have tried the other mainstream brands like Speedo and TRL. These are a great swim jammer that looks and performs better than the other - I also like supporting a local Southern California company. Fit is true to size, feels comfortable and very little drag in water. This will be my go to brand going forward for lap swimming. They also work great as a compression short to wear under your wetsuit. I have two pairs now and am planning on grabbing a third one.

The best of eight brands I have tried
This review will be posted to 7 different Men’s Swim Jammers products. Over the past two years I have gone through several different brands in search of the some that will work well for me. Some were good to excellent, and some were poor to terrible. I normally wear XL swim trunks and swim over a mile per session. The Best: Onvous fit well initially and continued wear well over dozens of swim sessions. While they are showing some signs of wear the amount is acceptable considering use. This will be my brand of choice going forward. Be sure to order one size up. 361 is a close second with good fit initially and over time. They showed a bit more wear over time in the form of piling and thinning. Not a bad choice and I will probably keep a pair in rotation for a change of pace. Be sure to order one size up. Xioker had the best fit initially. Be sure to order your regular US size. They were good in the pool for a few sessions then the sizing deteriorated. They still fit well when dry, but they stretch out when wet and actually slide down. Not what you want when swimming laps. If you are just splashing around in the water, they are fine, but don’t be surprised if your back side gets exposed when you dive in with wet jammers. Speedo was probably OK, but I was not comfortable with the cut. They rode too low on my hips, so I returned them without ever swimming in them. Snowshin, DressyButtons, Kilometre, and Srnfean all had issues with fitting well when wet. They fit well when new and dry, but once they got wet, they went loose. Definitely avoid.

Very well made
bought size 28. My son is 5'8" 130LBS. It fits very snug which is ideal for diving in the pool. The color was very nice and the fit was about 2-4" above the knee. So far he has not used it in the pool but judging from the quality I feel it will hold up very well.

Excellent swim suit!
Great fabric, great look and great fit matching my exact waist size as advertised. I love them and find them perfect for my lap work. Thanks!

Last longer than others I have worn under the same conditions
lasted much better than others I have had (9 months). 1.5 years with 3 weekly mile swims. Now a little stretched out.

Some designs are great but some fail after first use
I own 4 pairs. 3 are fine, but one failed after only 2 swims. I like their designs. I like the fit. Sizing is great. However, the fabric can differ based on design (or maybe batch to batch). I have some gray ones which are holding up for months of weekly swimming. However, the one pictured here failed after 2 swims only. Returning.

Good fit and dries fast.
Should have bought more when they went on sale. Worth every penny. Definitely will be buying again with different colors. I’ve had Speedo and these fit and feel better in my humble opinion.

Material bobbling on rear
I swim every morning and then use the sauna. These are staring to bobble on the bottom. I’ve had these less than 1 week and used less than 7 times. I will be returning these and seeking a refund!
