Cressi F1 Frameless Mask

The Cressi F1 is a no-nonsense frameless mask that nails the essentials — ultra-low volume, a reliable seal, and a fold-flat profile that makes it a travel favourite for good reason.

The F1 has been around for years and has quietly become one of the most recommended masks among dive instructors across Australia. Its appeal is simple: one large lens, no frame, minimal internal volume, and a silicone skirt that seals against an unusually wide range of face shapes. At $62, it is also one of the most affordable quality masks on the market. Whether you are teaching open water courses at Rapid Bay or free-diving the Poor Knights, the F1 does its job without fuss.

## Overview

The F1 uses a single tempered glass lens bonded directly to the silicone skirt with no rigid frame in between. This frameless construction achieves two things: it keeps the lens as close to your face as possible, maximising your field of view, and it drops the internal volume to a minimum. For freedivers, that low volume means less air spent equalising. For scuba divers, it means quick, effortless clearing if water creeps in. The skirt uses a smooth, non-textured silicone that forms a reliable seal, and the whole mask folds flat for packing.

## Key Features

- Single tempered glass lens with frameless construction - Ultra-low internal volume suited to both freediving and scuba - Soft hypoallergenic silicone skirt with wide sealing surface - Fold-flat design — packs into a pocket or BCD pouch - Simple push-button buckle system - Weighs very little, under 200 grams

## The Good

- The low internal volume is the standout feature. Clearing this mask takes barely any effort, and freedivers will appreciate how little air they need to equalise at depth. It is a genuine advantage when you are pushing past 20 metres on a single breath at Blowhole in Jervis Bay. - The single lens provides a wide, uninterrupted field of view. There is no centre bar splitting your vision, which makes a noticeable difference when looking straight ahead at a passing eagle ray. - The fold-flat design is genuinely useful for travel. You can roll this mask into a soft pouch and tuck it into your carry-on without worrying about a bulky mask box. For anyone doing regular trips to the Coral Sea or Bali, that convenience adds up. - The fit is impressively versatile. Across our team, divers with quite different face shapes got a comfortable, leak-free seal without needing to overtighten the strap. - At $62, it undercuts most comparable masks by a decent margin. You are getting excellent silicone and tempered glass at a price that makes it easy to recommend as a first serious mask. - Trusted by instructors. There is a reason so many Australian dive professionals keep an F1 in their bag as a reliable backup or daily workhorse.

## The Bad

- The buckle system is basic. It works, but it is not as smooth or quick to adjust as the ratchet-style buckles on more expensive masks. Adjusting mid-dive requires a bit more fiddling. - Downward visibility is average. The single-lens design favours forward and peripheral vision, but you do not get the same angled-down view that inclined twin-lens masks offer. If you spend a lot of time looking at gauges or scanning substrate directly below you, this is worth noting. - The skirt, being frameless, can distort slightly if you press the mask too hard against your face during a fit check. It is not a problem underwater, but it can give a misleading impression in the shop. - Colour options are limited compared to some competitors. If matching your mask to your wetsuit matters to you, the selection is fairly narrow. - No integrated fog-stop system. You will need to use defog solution or the old toothpaste trick before your first few dives.

## Verdict

The Cressi F1 does what a good mask should: it stays out of your way and lets you focus on the dive. Its ultra-low volume and frameless design make it a natural pick for freedivers, but it is equally at home on a scuba dive at the Navy Pier or a discover scuba session in the Whitsundays. The buckles are basic and the downward view is nothing special, but at $62 with this level of comfort and reliability, it is hard to argue with the value. A deserving staple in any Australian diver's kit bag.
