Windproof & Waterproof Jackets

Of course! On decathlon.com.gr you will find a huge variety of technical waterproof hiking and mountaineering jackets that cover every need and every hiker! Choose the ideal one for you, ranging from lightweight waterproof jackets for a sudden summer shower to heavy-duty, technical 3-layer jackets for demanding mountain trails.

The ideal solution to stay covered all year round is a 3-in-1 hiking jacket. These jackets consist of two independent pieces zipped together: a 100% waterproof and windproof outer layer and a warm inner layer (fleece or padded synthetic jacket). In winter you wear them together for maximum warmth and protection, while in autumn and spring you can wear just the outer waterproof layer for the rain. On cool summer evenings in the mountains, you can wear just the warm inner jacket.

A key feature that sets technical waterproof hiking jackets apart is proper breathability. At Decathlon, we measure breathability using the RET index (Resistance to Evaporative Heat Transfer). The lower the RET index, the more breathable the jacket is:
RET < 6: Extremely breathable, ideal for intense hiking and running.
RET between 6 and 12: Very breathable, ideal for classic hiking.
RET > 20: Low breathability.
Extra tip: Look for jackets with ventilation zippers under the armpits, as they allow for manual and immediate heat expulsion when hiking uphill.

Waterproofing is measured in millimeters (mm) based on the "Schmerber" standard. This indicates how much water pressure the fabric can withstand before it starts leaking.
2,000 mm: Basic protection for a brief, light downpour (approx. 2 hours).
5,000 mm - 10,000 mm: Good waterproofing for classic hikes in normal rain conditions.
15,000 mm - 25,000 mm: Top-tier protection, designed for multi-hour storms, torrential rain, or mountain blizzards.
Consult the description on each product page to check your hiking jacket's specific waterproofing rating and choose the one that suits you best!

Yes, provided you choose the right model! For heavy and prolonged rain, it is crucial that the jacket features 100% taped/heat-sealed seams so that water does not penetrate the stitching, as well as waterproof zippers. Decathlon's technical hardshell jackets with a rating over 15,000 mm are tested in a dedicated storm chamber for hours to guarantee you remain completely dry, making them the perfect choice if you are looking for a jacket to protect you from heavy rain!

Technical waterproof hiking jackets require specific care to retain their properties. First, wash your jacket in the washing machine on a delicate/synthetics cycle at 30°C, and remember to close all zippers and velcro fastenings and turn the jacket inside out. Use liquid detergent only, preferably one specifically formulated for technical apparel, and never use fabric softener or bleach, as they will clog the membrane pores and destroy breathability. When it comes to rinsing and spinning, set a double rinse cycle to remove all soap residues and set the spin speed to very low (maximum 600 rpm).
To maintain and renew your jacket's water-repellent properties (DWR), you can reactivate the coating by placing the jacket in the tumble dryer for 10-15 minutes on a low heat setting, or by using the specific DWR renewal sprays available at Decathlon.
