Looking to get a new training jammer for your time at practice? Here’s a breakdown of our favorite jammers, for lap swimming and training.
Jammers are comfortable and a more modest option compared to regular “Speedos”—aka swim briefs.
The look of the suit is similar to bicycle shorts, the fit is designed to be snug on your thighs and groin, and they provide the same amount of coverage as your average pair of swimming trunks, making them a popular option when it comes to training and lap swimming suits for men.
There are some key things to look for when picking out the best swim jammer:
🔑 Fabric: Most training jammers, unlike the Lycra-based racing jammers, are made of long-lasting polyester. The trade-off is that they do cause a little more drag, but they are far cheaper and will last much longer. Training jammers with a little bit of lycra in them will give the suit some stretch, but they will degrade faster than suits made of 100% polyester.
🔑 UV protection: Many swimsuits are UV-resistant. This means they will stand up to the sun and not fade prematurely. Particularly helpful for swimmers who have the luxury of training outdoors.
🔑 Drawstrings: If you are a competitive or experienced lap swimmer, you are going to be diving into the water, pushing off at full-force, and swimming at higher speeds with fins and paddles on. Drawstrings are a necessity to keep your suit snug around your waist, especially as the suit begins to naturally loosen and stretch out with repeated use.
🔑 Color: If you are swimming in open water, and the water temperature doesn’t necessitate wearing a wet-suit or swimskin, consider brighter colors in your suit to keep yourself visible and safe while paddling away.
Alrighty, with all of those things out of the way, let’s dive into our favorite swim jammers for training.
Speedo Endurance+ Solid Training Jammer
Speedo is the most well-known swim manufacturer on the planet, and for good reason—they’ve consistently put out great swim products tested and worn by some of the fastest swimmers on the planet.
When it comes to basics, the Speedo Endurance+ Jammer has got you covered.
The suit is made of a 50% polyester and 50% polyester, making it the most durable when faced off against the harsh pool chemicals in the water. Even after months of repeated wear, it will not lose shape, color, or pile. A four-way stretch keeps you comfortable and the suit dries relatively quickly for a polyester-based fabric.
The Speedo Endurance+ has got our top pick for best training jammer as it is super long-lasting, stays true to form thousands of hours of swimming later, and is available in a variety of colors and cuts (handy if you want to shift to a square-cut or brief at some point).
For you bigger fellas out there (including myself), you will be happy to know that the suit comes in up to 38”.
Speedo PowerFlex Swim Jammer
Yup, another Speedo jammer for ya!
Unlike the Endurance+, which is designed specifically for lasting as long as a 400m individual medley feels, the Speedo Powerflex Jammer has more Lycra in the suit, making it a little stretching (hence the name “PowerFlex”) and a little construction, making it marginally lighter and more hydrodynamic.
The increased Lycra does mean that the life of the suit will be less than more polyester-heavy suits, but if you are looking for something that provides the maximum range of motion, a suit that is lighter, and something that is a little faster than polyester training jammers, than the Speedo PowerFlex Jammer is your pick.
TYR Durafast Endurance Swim Training Jammer
TYR is another heavy-hitter in the swimming gear market, with top-tier athletes including Katie Ledecky, Ryan Lochte, and Cody Miller on their roster of sponsored athletes.
The Durafast is the training alternative to their popular racing jammer, the TYR Venzo, which I also reviewed recently. Unlike the Venzo, however, and its hefty price tag and wildly hydrodynamic fabric that lasts only a few dozen races, the TYR Durafast Training Jammer is designed for longevity.
Made of 94% polyester, and 6% lycra, it has enough to stretch to make moving your hips internally (as you do in breaststroke) easier. It has drawstrings (key for going ultra-fast), is available in three different solid colors, and will last you the season.
TYR Miramar Jammer
Another jammer from TYR is on our list, simply because this suit is tough. Made with TYR’s most durable and long-lasting fabric, a proprietary material they call Durafast Elite, the Miramar Jammer sits comfortably on the waist and provides plenty of range of motion for your swimming.
The suit comes in a variety of color combinations that are sure to make you stand out, and the poly fiber and circular knit construction is a solid 1-2 punch of stretchiness and durability.
This jammer is rated “chlorine proof” (let’s not kid ourselves, the suit will fade eventually, especially if you aren’t rinsing the suit after training) and provides UPF 50+ sun protection.
Arena Mens Spider MaxLife Panel Jammer Swimsuit
If you are looking for a no-frills practice jammer that is made of 100% polyester, the Arena Spider MaxLife Jammer is your ticket.
The suit has all the standard stuff you would expect from a lap training jammer: Adjustable drawstrings to keep your suit comfortable and secure, a long-lasting fabric designed to withstand pool chemicals, and plenty of colors and solid colors to choose from.
Nike Men’s HydraStrong Swim Jammer
Although Nike isn’t the swimwear brand that comes to mind when talking about swimming gear, they do make some pretty solid training equipment.
The Nike Men’s swim jammer, with its bright colors, front lining, and a wide variety of sizes, accommodating boys (22”) to us bigger guys (38”), is an excellent choice. These jammers are also available in a variety of vibrant prints and solid colors.
