## Assos TRAIL Liner Shorts ST T3

This super-lightweight **MTB liner short** from the Assos TACTICA line is designed for less intense riding like touring, bike parks, e-MTB, and commuting. At its core is the new **OFF‑ROAD ST T3 Insert** with 6 mm of padding thickness — 33% thinner than the high-performance equivalent found in the HP models, yet thanks to its two-layer construction it still dampens vibrations and distributes impacts effectively. The ultra-breathable **Airflow.1299** knit fabric delivers maximum breathability, making these liner shorts ideal in warm conditions above +21 °C. The fit hugs like a second skin, layers smoothly under shorts or pants with minimal friction, and is built around a comfort-focused, secure **comfort‑Fit** design.

- **OFF‑ROAD ST T3 Insert**: 6 mm, two-layer, thermoformed to reduce edges and irritation
- **Airflow.1299**: ultra-lightweight, highly breathable warp-knit fabric
- **zeroPressure Waist**: soft, highly elastic waistband with no pressure points
- **Superlight Leg Grippers**: light, secure hold without digging in
- **3D Waffle**: patented, three-layer perforated foam for increased air circulation
- **goldenGate 2.0**: flexibly mounted panel that moves naturally with your hips and pedal stroke
- **Reversed Seams** and standard-length legs for low-friction layering
- Recommended use: touring, bike parks, e-bikes, commuting; breathability 5/5, quick-drying 5/5

## Technical Details and Features

The **Shock‑Absorb Damping Mono 6** of the ST pad uses compressive foam layers and is tailored to the more upright positions typical of off-road riding; the **Thermoformed** shaping noticeably reduces material edges. The insert combines **3D Waffle** for enhanced ventilation with **goldenGate 2.0**, where the front and rear edges are anchored while the sides and centre move freely with your body — so the pad follows your movement instead of rubbing against it. The main fabric **Airflow.1299** is the lightest TACTICA liner textile, anchoring its airy mesh structure with a stabilising zigzag binding effect. All primary seams are reversed to further reduce skin friction, and the leg length increases overlap with outer shorts for a clean, integrated system.

## Riding Scenarios and Benefits

As the base layer of the **TACTICA System**, these liner shorts work best worn under cargo shorts or lightweight trail pants — for example paired with the TRAIL TACTICA Cargo Shorts T3 or the **MILLE GTC ZEPPELIN Cargo Shorts**. The focus is on everyday versatility, minimal weight, and maximum **breathability**, keeping you dry and unrestricted whether you're on singletrack, riding to work, or out on a summer gravel adventure. The **zeroPressure Waist** distributes hold comfortably across your waist, while the **Superlight Leg Grippers** keep everything in place without pinching — perfect for long days in the saddle or back-to-back bike park laps. Recommended for warm conditions above +21 °C, with a clear strength in **quick-drying** performance and minimal insulation when heat management is what matters most.

Further commentary on the TACTICA platform from specialist media reinforces the system approach: Assos positions TACTICA as a modular off-road kit for gravel, bikepacking, and adventure riding, with a focus on durability, storage, and comfort. This fits perfectly with the role of the ST liner as a breathable base layer for **touring** and moderate trail riding, while HP models cover the performance end of the spectrum. Depending on your terrain — from the trails on Zurich's Uetliberg to the rolling paths of the Bernese Mittelland — you can mix and match precisely without compromising on feel. Media coverage and manufacturer communications consistently highlight technologies like the **zeroPressure Waist** and the refined **Shock‑Absorb** pads as key to long-distance riding comfort.
