The standard wrist leashes of F-One wings have a very small diameter, even in the bigger sizes.
In summer it's OK, but in (Dutch) winter wearing a winter wetsuit / spraytop / drysuit / gloves the overlapping velcro is not more then 1-2 cm. Almost lost my Strike 4.2 once when the wrist leash came off because off this.
There is a (hard to find) F-One replacement wrist leash, which is wider and has a bigger diameter, but it comes with the leash cord and it's still on the small side when wearing winter gear.
Does anybody have a solution for this? Are there (big diameter) wrist leashes that are sold seperately? I don't like the coil leashes, so a boogieboard leash is no solution for me.

Agreed. Same problem here in Canada. Our windy seasons are all in rubber. I contacted Fone Friday . They responded quickly

"Thank you for emails, it's always great to have feedbacks from customers.

Your remark will be passed on to the R&D service. However, we don't have any larger wrist leashes to provide you with at the moment. "

Awesome wings otherwise. I had been attaching to my waist belt as a work around but now also have board reel attached there. Not comfortable with both on same.

interested what others suggest. I like the design of the wrist leash. Having the strap go through the metal loop gives some additional protection from accidental release

Never had that issue myself, you could try the Ozone wrist cuff: www.kingzspot.com/products/wing-wrist-strap. Dont know who your dealer is, but F-One and Ozone is the same distributor in NL, maybe your own dealer could also provide you with one. The leash cuff can quite easily be removed from the F-One leash. I know the delivery times for Ozone gear is quite long in NL though, because they only every once in a while ship a batch of stuff in.

Try using a short board surfing leash designed for use on your ankle.. That's what I use.
