Keep your eyes out for the waterproof breathable fabrics many shells are made of these days. Whether walking at dawn, dusk or night, these clothes may make it easier for vehicles and other pedestrians to see you. Regardless of how you get enough water before, during and after your walk, experts emphasize how important it is to drink. Water not only cools your body, it also helps carry oxygen and energy to your muscles and waste away from your muscles. If you're not properly hydrated, you risk a bad walk, cramps and, sometimes, even heat stroke.
Many people walk with water bottles in hand.
The benefit of Camelbaks is they allow to you stuff extra layers in the backpack part and provide hands-free drinking access. A good rule of thumb is to drink one glass of water about 10 minutes before you set off. While on your walk you should drink approximately one cup of water for every 20 minutes you walk. Keep in mind that if you're thirsty, it means you're already dehydrated, so if this formula doesn't work for you, adjust it to suit your needs. Also remember that drinking a lot of water all at once can lead to cramps.
