Hollis F1 LT Scuba Diving Fins

Hollis F1 LT Fins: Open-Heel Travel Fins Built for Efficient Propulsion

The Hollis F1 LT Fins are open-heel scuba fins designed around a vented blade, spring-strap system, and a lightweight SEBS compound construction that keeps them practical for travel without sacrificing drive in the water.

If you are a recreational diver who moves between destinations and wants a fin that packs light but still performs on a proper dive, these are worth a serious look.

What the Blade Actually Does

The F1 LT uses a vented blade design, which means the blade has channels cut through it to let water pass in a controlled way rather than fighting against a solid surface on the recovery stroke.

Done well, a vented blade reduces the effort it takes to bring your leg back up, so more of your energy goes into the power stroke pushing you forward. Hollis adds a unique channel along the blade tips specifically to manage stress on the material and direct water flow off the blade more efficiently.

The result is a fin that is meant to feel smooth through a full kick cycle rather than heavy and resistant on the upstroke.

Material and Why It Matters for Travel

Most fins in this category are built from rubber or stiffer thermoplastic. The F1 LT is constructed from SEBS compound, a softer, more flexible synthetic material that is notably lighter than traditional rubber blades.

That lighter weight is the practical reason to choose this fin over a heavier performer if you are frequently checking bags or watching airline weight limits. You get a fin that travels without penalty and holds up to regular use.

SEBS also tends to be durable under the kind of knocks and temperature swings that come with travel diving, so the lighter weight is not a trade-off against longevity.

Fit: Spring Straps and Foot Pocket

The F1 LT runs spring heel straps rather than rubber buckle straps. Spring straps snap on and release quickly at the surface, which matters when you are rolling off a boat and need to gear up fast, or when you are back on a ladder with tired legs.

The straps have multiple mounting positions, so you can dial in the tension and placement to match your boot thickness rather than accepting a single fixed fit. The mounts are also angled to improve the transfer of power from your leg through the strap into the blade.

The foot pocket is described as generous, which generally means it accommodates a range of dive boot sizes without pinching. If you dive in 3mm or 5mm boots across different trips, that flexibility is useful.

Heel tab loops let you hang the fins to dry or clip them to a locker hook, a small detail that saves time at a busy dive centre.

Sizing and Colour

The F1 LT is available in multiple sizes and comes in all black. If you need a specific colour option, this is not the fin for you.

Who These Fins Suit Best

The F1 LT is a strong match if you:

• Travel regularly and want a fin that does not eat into your luggage allowance
• Dive in varying conditions and wear different boot thicknesses depending on the destination
• Want spring straps for fast, reliable entry and exit without fumbling with buckles
• Prefer a smooth, efficient kick over a stiff, high-thrust blade

Where to Think Twice

If you dive primarily from shore at a home site and never worry about bag weight, the travel-focused construction may not be your priority. A stiffer, heavier blade can produce more raw thrust per kick, which some divers prefer in strong currents.

The F1 LT is also not a full-foot fin, so it requires dive boots. If you are looking for a barefoot warm-water option, this is not it.

For most recreational divers who move around and want a reliable, easy-to-manage fin that performs honestly in the water, the Hollis F1 LT is a practical, well-considered choice.
