The most important aspect of a scuba snorkel is of course that you can easy breath from it. The easiness of breathing is affected by the diameter of the tube (bore), the length and the shape of the tube and mouthpiece.
Generally speaking, you look for a large bore that you don't breathe like through a soda straw. The tube should not be too long or to short. 45 cm/17inch, give and take, is about the industry-standard. To short snorkels might not stick high enough out of the water while to long ones make it hard to clear them and you re-inhale too much already used air (also called dead air).
The bends if the snorkel has to be smooth and round as sharp edges will increase the breathing residence.
Another feature of today's popular snorkel is a slightly bended tube so it stays closer to the contour of your head to minimize drag. Most new designed Snorkel have also an optional self-draining one-way valve at the bottom of the tube. That makes it very easy to clear water from the snorkel as you simply need to exhale. The top end of the tube should be marked with a bright red tape to make it easy for boats to recognize the snorkeler.
Some snorkels have also a flexible lower portion what makes the use if it more comfortable. It also makes the snorkel drop away from the mouth area when changing to the regulator on the surface.
Most snorkels are a combination of plastic for the tube and silicon for the mouthpiece and the lower portion and available in many colors to match our mask and mask strap.
