MY KILOMETRE Jammer Swimsuit Mens Solid Endurance Long Training Jammer
Product description
What this is and what it’s for
The MY KILOMETRE Jammer is a men's training swimsuit designed for regular swim practice and fitness sessions. It’s a solid, long-cut jammer intended to stay comfortable through repeated laps and tough pool workouts. If you value longevity and practicality in a training suit, this model aims to provide a dependable option for routine sessions.
How it’s made and what it does on paper

On the fabric front, the jammer blends 81% Polyester with 19% Special Spandex. The combination is aimed at resisting sagging and bagging, which helps the suit keep a look and fit closer to new for longer. An important practical detail: the front lining and a drawstring waist offer additional support during sets and starts. The four-way stretch technology is there to support movement in all directions, with soft, comfortable wear as a follow-on benefit.
Quick take on durability and maintenance
A core claim is chlorine resistance, with the fabric promoted as able to handle regular pool use without significant shape loss. The care guidance is straightforward—hand wash in cold water, hang to dry or lay flat, and avoid hot water or direct sunlight. Practically, this means it tends to be a low-fuss option for weekly training if you follow the care steps.



What stands out in everyday use
It’s designed for training and fitness swimming, not triathlon or racing specificity. The internal front lining together with the drawstring allows for a personalised fit during long sessions. The emphasis on dry-fast performance and shape retention suggests fewer interruptions due to discomfort or bagging mid-workout.
Possible limitations and who it’s best for

This isn’t a premium race-cut option, so if you’re chasing the absolute lowest drag or the lightest fabric for competition, you may want to review other options. The fabric composition is fixed (81% Polyester / 19% Spandex) which provides durability and stretch but may not suit swimmers seeking high-end, lightweight materials. It’s likely well-suited to regular pool workouts and beginners to mid-level training rather than elite racing situations.
Who it’s for and who may want to skip it
Consider this jammer if you prioritise value-for-money, durability, and consistency in fit for routine training. If your focus is cutting-edge performance wear or you swim in very chlorinated pools daily and demand maximum long-term chlorine resistance, you may want to compare alternatives with different fabric technologies or cut profiles.



What to check before buying
- Confirm your approximate inseam length and waist size to ensure the jammer’s fit aligns with your body and preferred feel.
- Be aware of care requirements: avoid hot water and direct sun to maximise fabric life.
- If you have a particular sensitivity to lining or waistband comfort, consider how the front lining and drawstring arrangement will suit you over longer sessions.
A practical comparison in context

For everyday training, this jammer sits between basic entry-level suits and more specialised endurance options. If you swim several times a week and want something that holds its shape and dries relatively quickly, this could be a sensible middle-ground choice. If you need ultra-light racing gear or advanced chlorine inhibitors, you might look at other fabrics and designs.
Practical example of use
Picture a mid-length lane session: you dive in, settle into a steady pace, and appreciate the security of a drawstring that stays adjusted through a rigorous set. The lining helps prevent chafing on the front, and you notice the fabric remains comfortable as you push through intervals.



Is it worth it?
Final verdict: It makes sense if you prioritise durability, ease of maintenance, and a dependable fit for regular pool training rather than top-tier racing performance. If those are your priorities, this jammer delivers practical value for daily use. If your needs lean toward advanced materials or race-specific shaping, you may want to explore other options.
FAQ
- How durable is it in a busy chlorine pool? The fabric is marketed as chlorine resistant with shape retention, but real-life longevity will depend on pool conditions and care.
- Can I machine wash this? The guidance provided emphasises hand wash in cold water, machine washing isn’t mentioned, so it’s safest to follow hand-wash practice.
- Will it fit true to size? The presence of a front lining and drawstring suggests some adjustability, but exact fit will depend on personal measurements. If in between sizes, consider sizing up for comfort during longer sessions.
What to know before purchase
It’s a straightforward training jammer with a focus on durability and wash-and-wear practicality. It isn’t presented as a premium racing suit, so if you’re seeking lightweight speed or cutting-edge fabric technologies, setting expectations accordingly will help you decide.
