X 10 TRAIL VEST: MASSIVE 10L CAPACITY IN A RACE READY FORMThe Instinct X 10 delivers 10L of storage in a low-profile, ergonomic silhouette that hugs the body for a secure, bounce-free fit. Designed for speed and endurance, it offers plenty of space for long runs or fastpacking without compromising on comfort or freedom of movement.
What is the Instinct X10 Trail Running Vest?
The Instinct X-10L is a high-performance trail running vest built for endurance athletes who demand efficiency, comfort, and quick access to hydration and gear. Designed to sit high on the torso for unrestricted movement, it allows runners to store and retrieve essentials without stopping. Whether you're racing through rugged mountains or training on local trails, this vest got you covered.
What is it made of?
The X10 vest is constructed from Cordura Nylon 6.6 ripstop, a high-performance fabric engineered for durability and resistance to abrasions, cuts, and tears. This tightly woven nylon is widely used in technical outdoor gear because it balances toughness with a lightweight feel, ensuring the vest can withstand rugged trails and repeated use without wearing down quickly. The ripstop weave reinforces the fabric by incorporating a grid of stronger threads, preventing small tears from creating and spreading and significantly increasing the vest's lifespan in demanding environments.
The shoulder straps and back panel are made from 3D mesh, an open-structured material that allows superior air circulation and moisture management for enhanced breathability and comfort. Thanks to it, heat and sweat dissipate quickly, keeping you cooler and drier even during high-intensity efforts. Unlike traditional mesh, 3D mesh adds a cushioning effect, reducing friction against your skin and improving overall comfort, especially when wearing the vest for extended periods.
What are its features?
The Instinct x10 vest is about easy access, smart storage, and adaptability for ultra-distance adventures.
With multiple front and back pockets, including two XL zippered compartments, you can securely store energy gels, snacks, or your phone. An additional 150ml shoulder pocket with an internal cord ring and a built-in whistle ensures safety on remote trails.
The back of the vest features a horizontal 800ml pocket with an elastic cord for securing rain gear, plus additional compartments for gloves, headlamps, and other safety essentials. The 4L main zippered compartment provides ample space for bulkier gear, such as extra layers or emergency supplies.
You can carry your trekking poles however you prefer—front vertical storage on either side or horizontal/vertical storage on the back. This design allows you to quickly adapt to changing terrain and race conditions.
Adjustable chest straps and a refined side elastic lacing system allow for precise adjustments on the go. The auto-locking compression cords ensure your gear stays secure and bounce-free, even during technical descents.

Instinct X 10 Running Vest Review At Trekitt, we’ve seen a lot of running vests come through our doors, but the Instinct X 10 really stands out for one simple reason: it manages to carry a lot without ever feeling like too much. First off, the fit is superb. The low-profile, ergonomic design hugs your body like a second skin, no bounce, no rubbing, no fuss. Even when fully loaded, it stays put, which we found especially impressive during long, technical trail runs in the hills.
How many front pockets does it have for flasks, gels, or snacks? The Instinct X 10 Trail Running Vest offers ample front storage with five front pockets specifically designed for flasks, snacks, and quick-access gear:
2 high‑mounted soft flask pockets (≈650 ml each), positioned for effortless hydration on the move
2 lower stretch mesh feed pockets (≈600 ml each) ideal for gels, bars, or snacks
2 extra-large zippered pockets placed beneath the feed pockets—perfect for a smartphone or other valuables
And a small shoulder‑zip pocket (≈150 ml) on one side, complete with a whistle and cord ring for securing safety essentials
How Do You Care for the Instinct X 10 Vest? Looking after your Instinct X 10 is pretty simple—and worth it if you want it to last mile after mile. First things first: skip the washing machine. Just give it a gentle hand wash in cool or lukewarm water (nothing hotter than 30°C) using mild soap. After muddy or sweaty runs, a quick soak and rinse will do the trick. Then hang it up to air dry—no tumble drying or radiators, please! Once it's dry, store it somewhere cool and dry without cramming it into tight spaces, which can stretch out the mesh or straps.
