This new style of snorkelling mask allows you to breathe through your nose or mouth and actually remains higher out of the water than normal snorkels. A float in the top of the snorkel rises to close it off when you dive or in choppy water. But it’s the panoramic views from the full face mask which will appeal to many while also protecting the face from a jellyfish say… The Subea 500 Mask is from sports kit specialist Decathlon and is on sale for £24.99.
What’s more, the adjustable elasticated textile strap ensures it is comfortable to wear, and prevents it from pulling on hair strands. Meanwhile, the air circulation function prevents fogging, allowing reefs and underwater treasures to be enjoyed with thorough clear vision. Available in two sizes and several colours – featured is dark petrol blue, though we also found this on Amazon in a more sober black at £22.99 (prime) – see: HERE
Also check out the Decathlon Subea SNK 520 Adults or children’s Snorkelling Fins – at £8.99. These are described as being designed for adults who are still beginner snorkellers. The small bladed fin easily penetrates the water so that users can swim further underwater and explore even further when diving. 
The foot pockets are made of soft material to make the fins easy to slip on and off, perfect for when children want to dip in and out of the sea.
