When looking at a snorkel, there are two factors to consider. The first one is whether it has a valve or not. A valve at the bottom makes it easier to clear the snorkel of water.
The second thing to look for is whether it has a wave breaker at the top. A wave breaker reduces the amount of water flowing into the snorkel during use.
Additionally, the snorkel should be of good quality to ensure durability. All our snorkels are of high quality exclusively!
