Hardshell jacket Millet Trilogy Icon GTX Pro — waterproof breathable membrane, model 725459, size M, color saphir

Millet Trilogy Icon GTX Pro is a technical hardshell jacket designed for alpine and high‑intensity outdoor activities. It integrates a waterproof, windproof and breathable membrane to protect from heavy rain, snow and wind while allowing moisture vapour to escape. The jacket has sealed seams, an adjustable helmet‑compatible hood, articulated patterning for freedom of movement and a durable water‑repellent (DWR) finish to shed surface water. This model in saphir, size M, is intended to be used as an outer shell over insulating mid layers.

Advantages

The Gore‑Tex membrane provides reliable waterproofing and breathability under sustained aerobic effort. Sealed seams and taped zippers increase protection at critical points, while the DWR treatment helps water bead and run off the fabric. The articulated cut and adjustable closures enable layering and fine tuning of fit for climbing, skiing or fast alpine approaches. Lightweight reinforcement at high‑wear areas extends durability without adding unnecessary bulk.

Suitable for

• Alpine climbing and mountaineering where weather protection and mobility are required
• Technical trekking and multi‑day backpacking in wet or variable conditions
• Snow sports and ski touring when a waterproof breathable shell is needed
• General outdoor use as a reliable rain and wind shell over insulating layers

When it may not be suitable

This hardshell is focused on waterproof protection and technical performance rather than insulating warmth; it is not intended as a standalone warm jacket in cold conditions. For low‑intensity activities in mild, dry weather a lighter softshell or non‑membrane windshirt may offer better comfort and breathability.

Key specifications

• Membrane type: waterproof, windproof, breathable membrane
• Seam construction: fully sealed seams
• Hood: adjustable, helmet‑compatible design
• Finish: durable water‑repellent (DWR) treatment
• Cut: articulated for layering and mobility
• Closure: front waterproof zipper with storm flap
• Pockets: hand pockets compatible with harness or hipbelt access
• Fit: sized for layering (size M shown)

How to use

Wear the jacket as the outermost layer to protect against wind, rain and snow. Adjust the hood and hem to limit air and water ingress, and use ventilation zips during high exertion to regulate internal moisture. Combine with a breathable mid layer for thermal control; if wetting of the DWR occurs, refresh the finish with a suitable product following garment care instructions. Machine wash and reproof according to the manufacturer’s care label to maintain membrane performance and water repellency.

What to consider before purchase

• Intended activity: choose a hardshell for alpine, wet‑weather or technical use
• Fit and layering: ensure sufficient room for mid layers without excess bulk
• Hood compatibility: check helmet compatibility if using for climbing or skiing
• Care requirements: membrane jackets need correct washing and occasional reproofing

Usage recommendations

Use the Millet Trilogy Icon GTX Pro as a dedicated outer shell for wet and windy conditions, pairing it with breathable insulating layers. Maintain the DWR finish by regular cleaning and reproofing, and ventilate during activity to preserve comfort and membrane function.
