Hi Mark, I think it is a PTFE foil that has adhesive on one side. I bought 1m wide role in 0,13mm thickness and I’ve been using it on 3mm thick foam. The foil doesn’t stretch so it will form wrinkles on the pad. This is also visible in the video. I think there is also 0,08 and 0,05 thickness which could be more complicated but may not last long. I have also seen that Kopasz is using plastic bag over a padded seat.
Thanks Lukas, any info about this material. It’s teflon so I’m wondering how they attach it to the seat. Teflon I think is almost impossible to glue to anything.
hi Lukas i am planning on going on a trip to Norway and want to kayak 300 km in 7 weeks. i would like to make one of the pads but I don't really know the prosses or materials for example in eirik verås larsen boat what is the yellow ducktape looking material. do you know of any tutorials or anything? thx
Hi Magnus, Indeed, the material is Teflon tape, commonly known as PTFE tape. It's paired with a foam pad to provide a cushioned seat while still allowing for smooth, low-friction movement, which is crucial for efficient leg drive. For a touring trip, constant movement isn't desirable, so a stable foam pad would suffice to prevent sliding and ensure comfort. However, for ultra-marathon races where minimizing discomfort and maximizing power transfer is key, this combination can help reduce the risk of a sore bottom and maintain effective leg drive. In my sprint kayak, I opt for a 4mm medium density foam pad covered with a PTFE foil sheet, which I find to be more durable than tape as the strips can come loose over time. Ultimately, it boils down to trial and error to discover what setup works best for you personally.
