Why these picks

  • Ordering is mechanical: customer rating first, then review count, then a stable tie-break. Commission is not an input, and no listing can pay for a position.
  • 0 of the 24 listings carry a customer rating. Unrated listings are not hidden — they sort to the bottom, where you can still see them.
  • No brand quota is applied. Generic holds 6 of the 24 places because that is what the catalogue contains, not because it was favoured.
  • Prices and availability were last read from Amazon UK on 2026-11-01; 14 of the 24 were in stock at that point. Always check the live page before buying.
  • The mask's skirt material must offer sufficient flexibility for a good seal without being overly stiff, allowing it to adapt to changes in water pressure. Check the listing for details on the materials used.
  • The snorkel tube diameter should be appropriate for your breathing style; wider tubes are generally easier to clear but may require more effort to fill with air. Consider your own lung capacity and preference here.
  • The mouthpiece material needs to be comfortable against your lips and shouldn't cause any irritation or interference with your breathing. Look for soft, pliable materials.
  • The overall buoyancy of the system – largely determined by the inflatable vest – should complement your swimming ability and the conditions you plan to snorkel in. A high buoyancy is beneficial in choppy waters.

Buying guide

What to look for

Buoyancy and Weight Distribution

Snorkelling requires a degree of buoyancy to keep your face above the water, but too much can make controlling your movements difficult. The distribution of weight within your mask and snorkel system is crucial; a poorly balanced setup will cause you to constantly shift your head, tiring you out quickly. Consider the volume of air in your inflatable chest vest – this impacts overall buoyancy, though it's not the only factor.

Snorkel Length and Diameter

The length of your snorkel affects how much water enters when you breathe out. Longer snorkels generally allow more water to pass through but can be harder to clear quickly. The diameter impacts airflow resistance; a narrower snorkel requires more effort to breathe through, particularly at depth. A wider snorkel is easier to blow clear, but may require more effort to fill with air.

Mask Seal and Fit

A comfortable and secure mask seal is paramount for a good snorkelling experience. The fit should be snug around your face without excessive pressure. Check the skirt's flexibility; it needs to conform to your facial contours effectively, but shouldn't restrict movement. Ensure no gaps exist between the mask and your skin – this allows water ingress.

Clearance for Breathing

Snorkelling demands a clear pathway for breathing without significant resistance. The snorkel should be designed to minimise water entry during exhalation, allowing you to quickly expel air and clear the tube. Consider the angle of the mouthpiece – it needs to align comfortably with your mouth's natural position.

Common mistakes

  • Buying a large buoyancy vest for use in calm conditions: Many inflatable vests are designed for choppy waters where increased buoyancy is needed. A larger vest will make you overly buoyant and difficult to control, increasing the risk of capsizing. Check the product description carefully – look for specifications regarding intended water conditions.
  • Choosing a snorkel with an excessively narrow diameter: While a narrower snorkel might be more efficient in certain situations, it can create significant resistance when breathing out, especially at depth or when tired. Ensure you have sufficient lung capacity before opting for a smaller tube.
  • Ignoring the fit of the mask: A poorly fitting mask creates leaks and discomfort, leading to an unpleasant experience. Pay close attention to the skirt's flexibility and ensure it conforms comfortably to your face without excessive pressure. Measure your facial measurements (cheekbone width, jawline length) to compare with manufacturer specifications.
  • Assuming all snorkels are interchangeable: Snorkels vary significantly in terms of diameter, length, and valve design. Using a snorkel designed for open water in confined spaces can be problematic.

Frequently asked questions

How much do snorkelling equipment under £20 cost in the UK?
The 24 snorkelling equipment under £20 on this page run from £2.39 to £18.39, averaging £11.88. Half of them are listed at or below £12.28. Amazon UK prices move, so treat these as the figures at the last catalogue refresh rather than today's shelf price.
Which brands make snorkelling equipment under £20?
16 brands appear in this selection: Generic (6), Findway (3), Mares (2), BEAZOOM (1), CRESSI (1) and FSTIANXIA (1), plus 10 more. The number in brackets is how many listings each has here, not a ranking of the brands themselves.
How many snorkelling equipment are under £20?
24 of the 42 snorkelling equipment we list — about 57%. Everything outside that 57% is still on the main snorkelling equipment page; this page is a filtered view of it, not a separate catalogue.
What does 'waterproof' actually mean in relation to a mask?
'Waterproof' doesn't indicate the ability to withstand pressure. It refers to the skirt's material effectively preventing water ingress when the mask is correctly fitted and sealed. The listing should state the materials used; silicone is generally more effective than rubber.
How do I clear a blocked snorkel?
Most snorkels have a purge valve – typically a button on the mouthpiece – that forces air through the tube to dislodge any trapped water. Practice this technique regularly before you go snorkelling. Ensure the valve isn't blocked itself.
Is it possible to measure my face for mask fit?
While there are general guidelines, precise measurements aren't critical. However, measuring your cheekbone width and jawline length can help you compare with the manufacturer's specifications – look for these dimensions in the product details.
