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 4.2 Strike 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.

Here's a video about the importance of getting the leash attached properly. If the leash arm attachment comes off your wing is in jeopardy.

Same issue here. Really annoying F-One did this bc their old Swing Velcro cuffs were larger.
Today also wearing a 5mm wetsuit and in cross offshore conditions (so definitely didn't want the leash to come off!) I attached the leash to my waist belt rather than my wrist. Really liked that actually! Allows paddling too without arm being yanked.
