The Scubapro Apnea Snorkel is lightweight and foldable, and comes at a really attractive price point. It is made from non-toxic silicone, and the upper breather part can be removed, if you prefer a shorter breathing tube, for maximum streamlining effect.

You can wear it by using the mask clip attached to your mask, else, you can remove the mask clip, and tuck the snorkel tube under your mask strap.

Dive instructors will like this snorkel, so that they can fold the snorkel when not in use, and will not violate most organisations' training standards of not using a snorkel to teach. Spear fishers and free divers usually hold the snorkel under the mask strap.
