Nicknamed because of their "Cheeselike" appearance, Aiguille Exploration are the original manufactures of BFD`s the new approach to Open Canoe floatation. A hot wire technology, shaped block provides extensive floatation (500N) , encased in an extremely durable vinyl/cordura shell.

The EPS block will absorb a nominal amount of water (0.02%) over a prolonged period under water - & does not break down inside the casing.

They are tough enough to stand on & if securely fastened will be the last piece of kit to come out of your boat if it is stuck!
By no means rocket science - the BFD will replace the need for airbags in the future.

Each BFD requires a D ring in the hull to remain securely in the canoe.

BFD Type1 are suitable for the vast majority of open canoes in use in the UK including the following:

OLD TOWN - Discovery 119, Discovery 158, Discovery 169, Discovery 174.
MAD RIVER - Intrigue, Explorer, Teton, St. Croix.
Venture - Prospector, Ranger
