Touchscreens work inside ziplock bags
Touchscreens do work inside ziplock bags, and this can be a cheap way to waterproof your phone. However, it is important to ensure that the ziplock bag is sealed tightly to prevent leaks. Some people double bag their phones for extra protection.
Ziplock bags can be a good option for waterproofing your phone when running in the rain, working on your car, or even at the beach. They can also be useful in the kitchen to protect your phone or tablet from splashes, ingredients, and dirty hands.
While ziplock bags can provide some water resistance, they may not be completely waterproof. Condensation can develop inside the bag from hot water and hot air, and it is possible for moisture to get in, especially if the bag is submerged or exposed to heavy rain.
It is also important to note that using a ziplock bag as a waterproof case may affect the cooling of your device, especially if it is in the bag for an extended period or if the device is working hard. Therefore, it is recommended to avoid intensive activities on the phone while it is in the bag.
Overall, while ziplock bags can be a cheap and convenient way to protect your touchscreen devices from water and dirt, they may not provide complete waterproof protection and should be used with caution.

Snack-sized ziplock bags are best
Snack-sized ziplock bags are a great option for a waterproof case. They are an inexpensive and effective way to keep your valuables dry when you're out and about. Whether you're going for a run, a hike, or just facing a rainy day, these bags can be a handy solution.
One of the key benefits of using snack-sized ziplock bags is their portability. Their compact size makes them easy to carry in your pocket or bag. This means you can always have one on hand, ready to protect your phone or other small gadgets when unexpected rain or water exposure occurs. Their small size also ensures that they don't add bulk to your belongings, which is especially important if you're engaging in physical activities like running or hiking.
Snack-sized ziplock bags are also advantageous due to their versatility. They can accommodate a variety of small items, including phones, MP3 players, and even small digital cameras. This makes them a flexible solution for protecting your valuables in a range of situations. Additionally, these bags are not just useful for waterproofing but can also help keep items clean and contain any residual wetness or mess, making them handy for various outdoor activities.
While snack-sized ziplock bags offer a good level of protection against mild wet conditions, it's important to note that they might not be sufficient for sustained or intense exposure to water. In cases of prolonged rain or activities like canoeing or fording rivers, it is recommended to use something more waterproof or consider double bagging to ensure your items stay dry.
To enhance the effectiveness of snack-sized ziplock bags as a waterproof case, there are a few tips you can follow. Firstly, ensure that the bag is properly sealed. Check that the opening is completely closed to prevent water from seeping in. Additionally, consider using a straw to suck out the air from the bag before sealing, as this improves touchscreen responsiveness. It's also worth noting that while touchscreens do work through the bag, it's advised to avoid intensive activities on your phone while it's inside, as cooling can become an issue.

Double bagging for extra protection
While using a plastic bag as a waterproof case can be a cheap alternative, it is not always the most effective method for protecting your items. Double bagging is a way to increase the protection of your items.
One user on Reddit mentions that they double bag their phone and use a straw to suck out the air before sealing the bag. This method increases the responsiveness of the screen. However, they also mention that the bag can act as an oven for the phone, especially when playing music, which can lead to overheating.
Another user on Backpacking Light recommends using two Ziplock bags for sustained rain and wet conditions. They also suggest that the opening of a single bag can come loose, the plastic can get worn out, and water can find its way in, so using multiple bags can provide extra protection.
It is important to note that while double bagging can provide extra protection, it is not a foolproof method. There is still a risk of water damage, as some users have experienced. In addition, it is recommended to avoid intensive activities on the phone while it is in the bag, as cooling can be an issue if the phone is working hard or in the bag for an extended period.
Overall, double bagging can provide extra protection for your items, but it is not a guarantee against water damage. It is essential to consider the conditions you will be facing and choose the appropriate level of protection for your devices.

Avoid intensive activities with the phone in the bag
While using a plastic bag as a waterproof case for your phone can be useful, it's important to avoid intensive activities with your phone in the bag. This is because the plastic bag can cause chafing during intense movement, such as running. Additionally, the plastic bag may not provide sufficient protection from moisture and sweat, which can damage your phone during intense activities.
If you're running or engaging in other intense exercises, it's best to avoid relying solely on a plastic bag to protect your phone. Instead, consider investing in a sweat-proof running belt or armband that can securely hold your phone and provide better protection. These options will allow you to maintain access to your phone while minimizing the risk of damage.
For runners, there are a few alternative options to consider. One suggestion is to use a running backpack, ensuring that your phone is placed in a pocket to avoid bouncing around. Another option is to choose a tank top with a concealed side pocket, made from breathable and stretchy fabric, to securely hold your phone during moderate exercises.
If you prefer to keep your phone close at hand, a running belt, such as the SPIbelt, can be a good solution. It features an expandable pocket that can accommodate phones up to 6.5 inches long, along with other items like keys, gels, and credit cards. However, it's important to ensure a proper fit to prevent bouncing and potential chafing.
In summary, while using a plastic bag as a waterproof case is an option, it's not ideal for intensive activities. Opt for specialized running gear or clothing with dedicated pockets to safely carry your phone during intense workouts or runs. These alternatives will provide better protection, comfort, and accessibility for your phone while you focus on your active lifestyle.

Ziplock bags are a cheap alternative
Some people double bag their phones and suck the air out of the inner bag with a straw before sealing it, as this makes the screen more responsive. However, it is important to ensure that the Ziplock bag is sealed properly and has no leaks, as water can still get in through the opening. For this reason, some people use multiple bags to protect their phones in sustained rain and wet conditions.
Ziplock bags can be used in conjunction with non-waterproof cases to provide an extra layer of protection. They are also useful for keeping items clean and containing any residual wetness. However, they may not provide sufficient protection for expensive items in very wet conditions, as some people have reported their phones being damaged despite being placed in Ziplock bags.
Overall, Ziplock bags can be a cheap and effective way to protect items from mild moisture, but they may not be completely waterproof in heavy rain or full immersion.
