Water Bottle

● Bottle Height. Keep in mind that some bottles are too tall to fit into coffee machines or the water dispenser of your refrigerator. Think of the different appliances you might want to use your bottle with and measure them accordingly.
● Interior Angles. The other consideration for a bottle's shape relates to ease of cleaning. If the bottle has sharp corners on the interior or a noticeable “bottleneck” it can be more difficult to clean. The bottle's mouth size can also impact your ability to clean your bottle.

For narrow mouth, because the shape of the bottle is fixed, you will have great difficulty reaching inside the bottle to clean it. You will be less likely to splash yourself when you drink the water, but this can be solved in a number of other ways, such as purchasing a straw or sports lid.
For wide mouth, You can insert ice cubes. You can insert a capsule-style water filter. You can fill it with other snack items like nuts or even crackers. You can also dip your bottle into a stream and quickly fill it up in the outdoors. Bottle brushes fit inside easily when you need to clean your bottle. And when you air dry your bottle, there will be enough airflow to ensure your bottle dries out.

There are mainly two types. Screw-top lids are often the default for an insulated stainless steel water bottle, while sporty plastic bottles often come with nozzles or spouts.
● Screw-Top Lid. Obviously, with a screw-top lid, you'll have to open the bottle each time you drink. You'll want to find a bottle with a durable lid that has a handle, so it won't fly out the window easily. Screw-top lids are most common for wide-mouth bottles, so you can easily gulp water from the bottle if you're thirsty or splash water over your head, if you're too hot. If possible, choose a bottle with relatively large ridges where the bottle screws on, so grime and gunk won't stick in the grooves.

● Sports Cap With Nozzle. These are most common on plastic bottles made of a soft, flexible material. You can pull them up with your teeth and then squirt or drip water into your mouth by tipping the bottom of your bottle up into the air. The nozzle is essentially used like a short, thick straw. Sometimes, you'll have to bite the end of the nozzle for the water to come out. One advantage of this type of lid is that it prevents water from splashing on your face. It also eliminates the likelihood of spills if the nozzle has its own automatic closing valve. As for disadvantages, water does not necessarily come out quickly. The nozzle also makes it easy for grime to form or for the smell or taste of flavored beverages to linger. Essentially, they're a breeding ground for germs from your saliva, so try not to share your water bottle with friends.

● Sports Cap With Spout. A variety of options that involve a flipping mechanism of some kind and a small straw-like spout or opening are available. Sometimes the short straw itself flips up, other times, a lid over the small spout flips up. The flipping may require you to pull the spout up to drink from it, or to push a button to make it appear. Unlike the nozzle, this style tends to have fewer nooks and crannies where grime can build up. Anyone who has accidentally dropped a nozzle-style bottle in the sand knows that sand can get stuck between the rubbery folds for a long time.

The handles on most water bottles are attached to the lid. The reason is that the lid is that one essential detachable part that you won't want to lose sight of. Think of it like the camera lens of your bottle. If you lose that lid, you'll be very disappointed.
● No Handle. Bottles with lids that don't have a handle are usually designed that way for a minimal look. However, by eliminating the lid handle, you're losing an important part of the bottles functional design. You'll never want to lose the lid of your bottle, so if you choose a bottle's with a lid that doesn't have a handle, do so at your own risk.
● Flexible Handle. Flexible handles can feel soft on the fingers. However, they may not hold up well over time. It also means that you'll have to grip the lid itself for a screw-top lid to open the bottle, which can be tricky if you've screwed it on too tight.
● Rigid Handle. A rigid handle makes the bottle more sturdy and durable, as well. With a rigid handle, you can easily clip the bottle to a backpack without worrying that the handle will break.

● Clips and Carabiners. Metal clips and carabiners are a great way to make your bottle more portable. With a durable carabiner, you can hook your bottle to the outside of a backpack, a belt loop or even a bicycle basket or frame. Keep in mind that clips work best with a water bottle that comes with a rigid handle.

● Water Bottle Slings. To enable hands-free movement and reduce bouncing, shoulder strap slings are another way to carry your water bottle on walks, hikes and day trips. Slings come in a variety of different styles, such as small pouches or straps. Try to find a secure sling with a durable, adjustable shoulder strap.

● Metal Straws. These days, protecting one another health is of utmost importance. When you carry a reusable bottle, remember that germs can spread very fast if you share it with others. You can eliminate this problem by stocking up on a set of metal, reusable straws. That way, your family or friends can drink from the same bottle without spreading contagious diseases.
