Outdoor water bottles are designed for outdoor activities such as field exploration, mountaineering, and camping. They are usually drop-proof, leak-proof, and heat-resistant. They have a large capacity and can meet the water requirements for long-term outdoor activities. Most outdoor water bottles are made of durable stainless steel or plastic, which have good heat and cold insulation effects. Many models also have a hangable design, which can be hung on a backpack or waist for easier carrying.
