The ION Wing Single Boardbag Core Slim 2026 is a lightweight, well-padded day bag designed specifically for the narrower shapes now common across mid-length and performance wing foil boards. It gives your board sensible protection for everyday storage, car journeys and trips to the beach without the bulk of a full travel gearbag. For 2026 ION has refined the Core Slim around a durable recycled outer shell, 5mm foam padding and a foil-compatible opening, so you can put the board away with the mast and foil still fitted. It is a particularly useful option if you regularly rig at home or want to move between launch spots without dismantling your complete foil setup every time. Why choose the ION Wing Core Slim? Made for slimmer wing boards: the narrower proportions are better suited to modern mid-length and performance foil boards than an oversized conventional wing board bag. 5mm foam protection: helps protect the rails, deck and hull against everyday knocks, scratches and transport wear. Foil-compatible opening: a Velcro opening underneath allows the mast and foil to remain attached to the board. Recycled outer shell: constructed using robust 100% recycled PU-coated PET 450D fabric. Heat-reflective underside: the light-coloured PE outer bottom helps reduce heat build-up inside the bag when it is sitting in the sun. Useful small-part storage: two external tool pockets plus an internal pocket give you somewhere sensible for screws, tools and other small essentials. Easy to carry: side and top carrying handles make it easier to manoeuvre a loaded board. Shoulder strap compatible: attachment points allow a suitable shoulder strap with carabiners to be added if required. Shoulder strap is not included. Who is the Core Slim for? This is a particularly good choice for riders using narrower wing, mid-length and crossover foil boards who want a close-fitting bag rather than putting their board into a much wider conventional wing bag. The foil opening also makes it very convenient for frequent riders who would rather leave the foil assembled between sessions. If your board is substantially wider, compare it with the ION Wing Board Bag Core, which is offered in wider dimensions. If you want to carry the board, foil components, wings and other equipment together for longer journeys, the larger ION Wing Gearbag TEC is the more appropriate option. 2026 ION Wing Single Boardbag Core Slim sizes Bag size Suitable board size 5'5" x 20" Boards up to approximately 165cm long and 50cm wide 5'9" x 21" Boards approximately 166–175cm long and up to 53cm wide 6'1" x 22" Boards approximately 176–185cm long and up to 55cm wide 6'7" x 24" Boards approximately 186–200cm long and up to 60cm wide Buying tip: do not choose purely from the quoted length of your board.

Core Slim vs a full travel bag The Core Slim is best thought of as a quality everyday board bag. Its 5mm padding is ideal for protecting a board around the garage, in the van and travelling to and from regular sessions. If you are flying with your equipment or want substantially more space and protection around a complete wing foil setup, we would recommend looking at a heavier-duty travel solution instead. You can also browse our complete range of foil and wing board bags if you are comparing different sizes or styles. FAQs Can I leave my foil attached to the board? Yes. The Core Slim has a Velcro opening underneath specifically designed to allow the mast to pass through the bag, meaning you can store or transport the board without dismantling the foil after every session. Is the ION Core Slim suitable for mid-length wing boards? Yes. This is one of the main reasons to consider the Slim version. Its narrower dimensions make it particularly well suited to the newer generation of mid-length and narrower performance wing foil boards. Should I buy the Core Slim or the standard ION Wing Board Bag Core? Choose the Core Slim if your board is relatively narrow and you want a closer fit. For wider conventional wing boards, the ION Wing Board Bag Core is normally the better option. Is a shoulder strap included? No. The bag is compatible with a shoulder strap using clip-on carabiners, but the strap itself is not supplied. Is 5mm padding enough for flying? We would regard the Core Slim primarily as an everyday storage and transport bag rather than a dedicated airline travel bag. For flights or more demanding travel, additional protection or a heavier-duty gearbag is advisable. Can The SUP Company help me choose the correct size? Yes. Send us the make, model, year and dimensions of your wing board and we can help check which bag is the most sensible fit before you order.
