Built For Athletes: The Brand That Gets It
Built For Athletes made its name in the world of elite fitness, supplying gear trusted by professionals across disciplines like CrossFit, HYROX, endurance racing, and more recently, F1.

Their kit became the benchmark for durability, smart design, and no-nonsense performance. The Pro Series is their most technical bag to date — and if you’re familiar with the brand, you’ll be well aware that’s a big deal.
The Versatile Travel Backpack That Works Wherever You Do
This versatile travel backpack is exactly that — versatile. Use it for your gym commute. Take it to work. Pack your Sunday best for that week-long break. It’s made for people who don’t like to slow down.
With two size options, you can pick the build that suits your life:
- 25L: Ideal for the daily essentials — think office, gym, short getaways
- 45L: Built for the long haul — travel, long hikes, camping, heavy-duty workouts, and multi-day use
Both options are crafted with the same military-grade materials and thoughtful details, meaning you’re not compromising on quality, regardless of size.
Serious Features That Make a Real Difference
This isn’t a bag that’s all talk. The Pro Series is loaded with functionality that makes real-world sense. Here’s what you’re getting:
- 180° clamshell design for suitcase-style access (no more digging through chaos)
- Dedicated, ventilated laundry compartment to keep clean kit and sweaty gear separate
- 360° anti-shock laptop sleeve for maximum tech protection
- Dual bottle holders to house water bottles or shakers (up to 1L each)
- Removable wet bag — perfect for used gym gear or a spontaneous swim
- Multiple compartments, including a separate shoe space
- YKK reinforced zips and rip-proof, waterproof fabric
- Ergonomic back panel and padded shoulder straps for carry comfort
- Infinity-strap compression system to adapt based on how light or heavy you pack
- Available in sleek Black or statement-making Concrete colourways
It’s not flashy for the sake of it — every element serves a purpose. It’s an everyday utility piece disguised as premium fitness gear that goes hard.
Who Is It For?
It’s no secret that Built For Athletes is firmly rooted in the fitness space, and the Pro Series is specifically designed with the elite performer in mind.
However, that doesn’t make it any less universal. This versatile travel backpack is for:
- Athletes and gym-goers who carry more than just headphones and a towel
- Frequent flyers who are fed up with basic cabin luggage or wheel-buckling suitcases
- Hybrid workers who move between co-working spaces, coffee shops and training sessions
- Adventurers who want durability without the bulk of traditional suitcases
- Anyone who appreciates clever design and a backpack that doesn’t quit
If you’re someone who lives out of a bag more often than not, this is the upgrade you didn’t know you needed.
Worth the Investment?
Let’s be honest — the price tag isn’t budget. The 25L comes in at £189.99, and the 45L at £199.99. But then again, this isn’t throwaway kit. It’s gear that’s designed to go the distance and keep you organised, comfortable, and ready for whatever the day throws at you.
And right now, you can trim 15% off the ultimate versatile travel backpack with the code GYMFLUENCERSAGENCY at checkout, which sweetens the deal considerably.
