Product Information

Full details

The MILLET Seneca 2.5L Waterproof Hiking Jacket is a technical outer layer designed for adult hikers who require reliable protection against wet weather. It features a high-performance 10K/10K DRYEDGE membrane and a DWR PFC-free finish, making it both waterproof and breathable. While it excels in rain-heavy conditions, users should note that as a 2.5-layer shell, it prioritizes lightweight mobility over the heavy-duty insulation of thicker mountain parkas.

FAQs

Is the hood adjustable?

Yes, the hood is designed to be fully adjustable to fit securely and provide protection during windy or rainy hikes.

Can I wash this jacket in a standard washing machine?

Yes, machine wash on a gentle cycle at 30°C using mild soap. Avoid fabric softeners.

What does 10K/10K mean?

It refers to the fabric's ability to withstand 10,000mm of water pressure while allowing 10,000g of water vapor to pass through per square meter, balancing waterproofing and breathability.

Does it have pockets for storage?

The jacket features two secure zipped hand pockets for storing small essentials.

Is this suitable for winter mountaineering?

It is a 2.5-layer shell intended for hiking. While it is windproof and waterproof, it is not an insulated jacket and would require appropriate layering underneath for winter temperatures.

Troubleshooting

Water is soaking into the outer fabric rather than beading off.

The DWR (Durable Water Repellent) coating has worn off. Wash the jacket and re-apply a DWR treatment spray.

Feeling damp inside despite the waterproof rating.

This is often due to moisture build-up from sweat. Open the under-arm ventilation zips to improve airflow and regulate internal temperature.

Pros and Cons

Setup, Compatibility & Care

To ensure your jacket remains waterproof, follow these care instructions: machine wash the garment on a gentle cycle at 30°C using mild detergent. Avoid fabric softeners as they can strip the DWR coating. For the best results, tumble dry on a low setting or air dry, and periodically apply a garment-safe DWR refreshing spray to keep water beading on the surface. When storing, keep the jacket in a cool, dry place and ensure it is completely dry before folding to prevent fabric degradation.
