Freediving Bags & Backpacks

Bags for Freediving and Freediving: dry backpacks, fin holders, duffel bags, thermal bags and travel luggage for transporting long fins, monofins, and freediving equipment Freediving.

Bags for Freediving and Freediving

freediving and freediving equipment creates transport challenges that a generic bag cannot adequately solve. freediving fins - with blades between 70 and 90 centimeters long - do not fit in a standard backpack. A monofin is even bulkier and requires dedicated storage. A neoprene wetsuit, wet after a pool or sea session, takes up considerable volume and releases water throughout the entire return trip. The freediving computer, low-volume mask, nose clip, and other technical accessories need protection from moisture and impacts.

The Bags for Freediving category from Deep Blue brings together solutions differentiated by type, capacity, and level of waterproofing: dry backpacks, fin bags, technical duffel bags, cooler bags, hard travel cases, and tool storage containers. The available brands cover a wide range, from entry-level technical products to premium solutions with certified waterproof sealing, used both for pool sessions and international freediving competitions, as well as for trips to open-water freediving destinations.

Types of Bags for Freediving and Freediving

Dry backpacks and waterproof duffel bags

Dry backpacks and duffel bags with waterproof closures are the most widely used solution among freediving practitioners traveling in marine environments, on boats, or by kayak, where the bag is exposed to direct splashes, waves, or heavy rain. The Yeti Panga line - available in 28-liter (backpack), 50-, 75-, and 100-liter (duffel) formats - is built with heat-welded TPU across all panels, with no exposed seams. The waterproof rotating closure maintains a watertight seal even in the event of partial submersion: this is not simple surface water repellency, but a construction that prevents water from entering through any point of the bag.

Backpacks and fin bags

Transporting freediving fins is the most common logistical issue among freedivers. Long blades are incompatible with any conventional backpack and are difficult to fit into standard gear bags without risking deformation. Dedicated fin backpacks - such as the Beuchat Mundial Backpack 2 and the Mares Ascent Dry Fin Bag - are built with an elongated vertical compartment that holds the blades at their natural length, with side compression straps that keep them in place during transport. This type of solution is especially useful for those who walk from home to the pool, or hike along the rocks to reach the entry point. A monofin can also fit in these solutions, provided the compartment’s maximum dimensions are checked against the actual blade length.

Multifunction Technical Backpacks

Multifunction technical backpacks are designed to carry a full freediving kit in a single shoulder-carried bag. The Deep Blue All-In Backpack and the Deep Blue All-In Backpack Pro are backpacks developed with organized compartments for fins, wetsuit, mask, and accessories, with padded straps and a back structure to distribute weight during walks. The Cressi Piovra Dry Backpack and the Mares Ascent Dry Backpack feature a waterproof treatment with a roll-top closure, protecting the contents even when the bag is placed on wet surfaces or exposed to rain. These models are suitable both for pool use - where relatively compact gear is carried - and for the ocean, where the required volume increases with the addition of the wetsuit and safety accessories.

Training and Competition Gear Bags

For those who practice freediving consistently, a roomy gear bag is the most practical everyday solution. The C4 Extreme Bag models (90 and 120 liters), Beuchat Explorer HD (90 and 114 liters), Salvimar Whale 135L, and the Cressi Gorilla Pro XL offer generous capacity with a wide top opening, reinforced handles, and high-density nylon materials treated with a water-repellent finish. They are not waterproof for submersion, but they resist splashes and the humidity typical of pool and seaside environments. Some models integrate wheels and a telescopic handle - such as the Beuchat Explorer Roll, the Mares Ascent Dry Duffle, and the Salvimar Roller Speargun Big 120L - to make transport easier when gear weight is high.

Thermal Bags

The soft coolers in the Yeti Hopper line are built with a Dryhide inner liner, a hydrophobic, mildew-resistant material, and ColdCell insulation that maintains the internal temperature for many hours. The zipper seals the main compartment airtight, preventing liquids from leaking even if the bag is overturned. For freedivers doing extended sessions at sea, keeping cold water and food available for breaks is a practical part of managing the day. Hopper coolers are suitable for use in marine environments thanks to Dryhide’s resistance to saltwater and UV rays, although they are not classified as waterproof bags for immersion.

Rigid Travel Cases for Fins and Monofins

Air travel with freediving equipment is a frequent necessity for those traveling to open-water freediving destinations, from the waters of the Canary Islands to Polynesia, from the Red Sea to the deep Mediterranean. Freediving fins and monofins, due to the length and fragility of their blades, cannot be packed in a soft duffel without risking damage during checked-baggage handling. The SporTube, line, in Series 1, 2, and 3 versions differentiated by maximum length, is built from high-strength rigid polypropylene with a telescoping structure that adapts to the actual length of the blades. It reliably protects even carbon blades, a material sensitive to compression and side impacts. The integrated locks support the use of TSA-approved padlocks, a requirement for many international flights with sports equipment.

Mesh Bags and Gear Cases

Mesh bags do not protect against water, but they serve a specific purpose: immediate drainage of wet equipment and ventilation during transport. After a pool or ocean session, wetsuits, fins, and accessories release water for hours. A mesh bag lets you collect all soaking-wet gear and keep it separate from the rest of the contents, helping it dry during transit. They are often used as a secondary container together with a main backpack. The Yeti Loadout GoBox 15, on the other hand, is a modular rigid polypropylene case with a waterproof gasket, suitable for organizing and transporting smaller accessories such as nose clips, clips, fasteners, and small parts that would otherwise get lost at the bottom of gear bags.

How to Choose a Bag for Freediving and Freediving

The choice depends mainly on three variables: the use case (pool, ocean, competition, travel), the type of equipment to be carried, and the mode of transportation used to reach the session location.

Pool sessions: the required volume is limited — wetsuit, fins, mask, nose clip, and accessories fit comfortably in a 30–50 liter technical backpack or a medium duffel. Water resistance is not as critical as it is at sea: a water-repellent material is enough. Models such as the Deep Blue All-In Backpack, the Cressi Piovra Dry Backpack, or the Mares Ascent Dry Backpack are suitable for this use.
Open-water sessions with walking access: a technical backpack with padded straps and a fin compartment is the most ergonomically sound solution. The weight is distributed across the back instead of loading a single shoulder or hand, reducing fatigue on even long approaches over rocks or coastal trails.
Open-water sessions from a boat or kayak: the bag is directly exposed to water. A dry bag or a duffel with a waterproof closure is the technically correct choice for protecting changes of clothes, electronic devices, and sensitive gear.
Freediving competitions: competitions often require transporting specific gear: competition wetsuit, carbon competition fins, dive computer, personal buoy, safety lines, in crowded environments with limited space. A roomy duffel with a wide opening and good internal structure makes it easier to prepare and retrieve gear between attempts.
Air travel to freediving destinations: the SporTube is the right solution for long fins and monofins. Paired with a soft duffel as an additional bag for wetsuit and accessories, it covers all the needs of a freediver traveling internationally.

One concrete parameter to consider is the volume of the wet wetsuit. A 3–5 mm neoprene wetsuit, once wet and compressed, takes up between 10 and 15 liters. With freediving fins, mask, nose clip, dive computer, and safety accessories, the total volume can easily reach 40–60 liters. Anyone using 7 mm wetsuits or two-piece combinations can easily exceed 70 liters. Undersizing the bag relative to the actual gear creates compression that can deform fin blades or damage more fragile components.

Materials and technical features

The materials used in freediving bags must withstand saltwater, UV exposure, abrasion on rocky surfaces, and the repeated wet-dry cycles typical of constant use. The main construction solutions found in this category are:

Heat-welded TPU: thermoplastic polyurethane is heat-welded across all bag panels, eliminating traditional stitching. Seams are the primary water-entry points in any conventional bag: heat welding removes them completely. The result is a structure that remains watertight even under hydrostatic pressure, passing immersion tests.
Waterproof roll-top closure: the wide-mouth opening is rolled over itself a minimum number of turns and then clipped at the sides. This system, derived from marine dry bags and military dry bags, requires no zippers and has no mechanical failure points. The seal is ensured by the physical principle of rolling, not by gaskets subject to wear.
High-density Nylon Oxford: used in the Beuchat Explorer HD, C4 Extreme Bag, Cressi Gorilla Pro XL, and Salvimar Whale models. Abrasion- and tear-resistant, with a surface water-repellent treatment. Not waterproof when submerged, but suitable for pool and shore use.
Roll-top closure (Cressi Piovra Dry, Mares Ascent Dry, Best Divers Military): a closure mechanism that folds over itself by rolling the upper edge of the bag. It provides a higher level of waterproofing than conventional zippers, although it requires a more careful closing procedure than the Yeti rotation system.
Rigid polypropylene (SporTube): a rigid thermoplastic material with high impact resistance. It maintains its shape even under the weight of checked airline baggage, protecting carbon blades from compression. The telescopic structure extends or retracts to match the length of the gear inside.
Dryhide + ColdCell (Yeti Hopper): Dryhide is a hydrophobic outer coating, resistant to mold and salt water. ColdCell is a closed-cell insulation that does not absorb moisture and keeps the internal temperature stable longer than the standard foams used in conventional cooler bags.

Practical use

Bag management in a freediving context changes significantly depending on the training environment.

In the pool, the usage routine is repetitive: you arrive with dry gear, change, train, and go back with everything wet. The bag must have enough volume to separate wet gear from dry items and must be able to be left poolside without absorbing ambient moisture. A waterproof backpack or one with a reinforced bottom is more suitable than an untreated fabric duffel, which tends to absorb chlorine and deteriorate more quickly.

In open water, the variables increase. If you drive to the shore, a large duffel bag is sufficient. If you arrive by boat or RIB, the bag must withstand spray and waves while underway. If you reach the dive site on foot along coastal trails or cliffs, an ergonomic backpack with adjustable straps is essential for comfortable carrying.

For traveling freedivers heading to specific destinations— islands, remote rocky coastlines, deep freediving sites—gear organization is an essential part of preparation. The most functional setup generally includes: a SporTube for fins and monofin as checked baggage, a soft duffel bag for wetsuit, mask, and accessories as a second bag, and a soft cooler backpack or Hopper bag as carry-on luggage for a computer, phone, food, and drinks during the flight and sessions.

Rinsing with fresh water at the end of a session is the most important maintenance step for any type of bag. Salt water accelerates corrosion of metal zippers, degrades treated nylon, and gradually reduces the effectiveness of waterproof coatings. TPU bags such as the Yeti Panga line can be cleaned with water and a mild detergent. The zippers on technical duffel bags should be lubricated periodically. All models should be stored open and dry to prevent mold growth, which is particularly common in closed bags with saltwater residue inside.
