The pouches are 8.5"x 6.2" and are made of a durable, soft pvc material (I compare it to the material of an inflatable intertube). The pouches have strong zip locks that creates a secure closure making them 100% waterproof. They are large enough to fit most devices, along with other valuables depending on the size of your device. The pouches not only protect from water, dirt, and dust; they can even protect your devices and documents from water vapor damage as well. There is an extra long, adjustable waist belt so the pouch can fit comfortably around your waist while you're on the go. There are two different colors of pouches in this set. One is blue and is somewhat transparent and a black one that isn't transparent at all. The blue pouch allows you the option of using your device while it's inside the bag. I personally put my phone in the pouch and tried this feature out. After doing so, I found that the touchscreen was very responsive through the pouch and when my screen brightness was turned up high enough I could easily scroll through my phone and was able to read it really well. The purpose behind the black pouch is to give you a way to protect your personal privacy. I put my phone in the black one as well and I could not see anything through it at all. I really like the idea behind these pouches and how well the idea was executed. The pouches feel sturdy and durable. I was impressed with how well the pouches are sealed. Once the zip locks are closed, you have to roll the top part down and then secure it with a Velcro closure. I think the company did a really good job at taking extra steps to make sure they are completely sealed. Overall, I think these pouches are well made and are a great way to protect your devices and valuables while you're outdoors! I would definitely recommend to others who are looking for a waterproof pouch. I received these products for free inexchange for a review, but all opinions are completely my own.
