TROY LEE DESIGNS ROCKFIGHT CE FLEX REVIEW

October 5, 2026

The Troy Lee Designs Rockfight is one of the first products that comes to mind when I think of body armor. It is the staple chest protector for those rocking exposed torso protection over a white T-shirt, which floods uplift queues every summer. Pitted against so many good options for chest and back protection on the market, implementing D3O technology has kept the Rockfight at the front of the conversation with the latest TLD Rockfight CE Flex. After abuse in bikeparks across the UK and beyond over the last few months, it’s time to share the final verdict on this torso protection.

ABOUT THE TLD ROCKFIGHT CE FLEX CHEST PROTECTOR

The Troy Lee Designs Rockfight CE Flex Chest Protector was designed to improve mobility over the other Rockfight torso protector models, without sacrificing the crucial protection elements. A removable D3O insert has replaced the traditional EPP back panel, giivng a flexible 40cm long back panel which offers CE EN1621 Level 1 Impact absorption. The CE EN 14021-certified EPP chest layer is designed to handle airborne trail debris and lower-speed knocks, with generous coverage wrapping around the torso.

TLD claim to have shattered safety standards whilst still retaining a slim and lightweight profile, coming in at a respectable 700g. The front panel is well ventilated, with minimal padding to ensure airflow. On the shoulders, extra padding is included where you need it to further aid in comfort and protection, and can be removed if you desire improved breathability.

The Troy Lee Designs Rockfight CE Flex Chest Protector comes in three sizes (XS/S to XL/XXL), with adjustability in the shoulder straps and flexible side-buckle straps. There is a choice of four colours, with a retail price of £160 / $185

THE DIRT

I’ve always been a big fan of D3O, and it performed as well as expected in the Rockfight CE Flex torso protector. It was lightweight, flexible, and provided excellent impact protection to keep me safe during some of the gnarlier moments.

In comparison, the EPP chest protector felt a bit crude and plasticky when first putting it on. However, in use, it proved to do its job very well. Thanks to an articulated panel design, the flex that the D3O offers wasn’t needed as much on the chest. Instead, the EPP layer did a good job of protecting the vitals while keeping the weight down. Yes, a D3O chest piece would be nice to cushion harder hits to the front, but the EPP “stone shield” layer still offered a suitable level of protection. It was able to offer this protection while maintaining a lightweight and more breathable experience.

Talking of the lightweight feel, at 700g there was an airy feel to the Rockfight when worn. I will happily admit that I personally prefer the fit and subtlety of in-built baselayer body armour in the winter. However, as the weather gets warmer, it can feel too hot for baselayer-style protection. Instead, the Rockfight offered an excellent lightweight and breathable option that I didn’t hate wearing when it was hot out. The airflow through the chest was especially good, and even the comparatively less breathable back panel didn’t leave me with humongous sweat patches at the end of the day. When it inevitably ended up getting sweaty, the removable D3O insert was easy to remove to let the remainder be and washed. As a result, it’s definitely my go to body armour on a warm day.

Even without being built into an undershirt, the Rockfight CE Flex didn’t chafe or itch when worn against bare skin. Whilst this is in part thanks to the extra padding where the straps contact the body around the shoulders, overall it didn’t feel abrasive or irritating, which surprised me.

There were a few complaints that cropped up over the testing time wearing the TLD Rockfight CE Flex torso protector. The back coverage is noticeably short: the D3O insert measures around 40 cm in length, so it left the lower spine somewhat exposed. The straps are also a bit bulky, which effected the subtlety when worn under a jersey. However, this bulk comes with 4 inches of adjustment to help dial in the fit. I also found that the Rockfight CE Flex had a tendency to ride up. It sometimes lead to an irritating tight-but-loose fit, which was far from a dealbreake, but worth mentioning. Choose your size and adjust the strapping carefully to prevent this.

At £160, you could opt for a more budget-friendly option, but the Troy Lee Designs Rockfight CE Flex is priced competitively. The base-level full EPP TLD Rockfight comes in at just over £100, but loses the comfort of the Flex version. £160 feels like a fair price for the D3O version considering the technologies used and its comfort.

The Wolf’s Last Word

Overall, I think there is a good reason why the Troy Lee Designs Rockfight is as popular as it is. It excels as a lightweight and breathable protection offering, with excellent airflow and an unencumbering feel. It’s not the most subtle piece of body armour visually, and I’d love extended coverage on the back protector, but on the whole I have been impressed with Troy Lee Design’s Rockfight CE Flex.
