Trail Shoes
Trail shoes with good grip are essential. Salomon offers reliable all-round performance, while Decathlon provides great value.
Hydration Vest
Essential for carrying water and nutrition. Salomon vests are popular for good reason, but Decathlon's alternatives do the job at half the price.
Trekking Poles
