It is possible Peak Retreats have a slightly different arrangement but booking direct I recently checked and, despite what it says on their site, apparently it is still possible to both use it and turn up any day (within 12 months of booking) - however, because they now have some peak days (which cost more) you could have to pay a supplement, hence they advise you to modify the date online (which could involve an additional payment). So it is still flexible in terms of usage but not necessarily in terms of cost...

For anyone yet to order one from Snowsafe, I think there is a January offer code: TW50 (50% off some Terrawest kit)

I think Terrawest is an own brand of Snowsafe, who I understand modelled it on the Ortovox, as you say. I have one and am very happy with it - it seems pretty close to the Ortovox (which we also have) although I cannot vouch for how robust it is as COVID has scuppered my trips since I’ve owned it... Snowsafe team are very helpful (i have no affiliation) and I think there are currently some good bundle offers in including avalanche safety stuff if you need more than just the pack.

@Dippy - I think driving, self catering etc which is what we do is very low risk in terms of Covid (and agree how you conduct yourself makes a big difference). My worry is something happens not in any way related to Covid but I have no insurance as whole policy invalid?

14 day isolation on return is difficult for most but will be possible for some. Are others not concerned more about the FCO advice re only essential travel (we could argue on this forum that skiing is essential but not everyone will agree) - surely this makes most if not all insurance invalid?

If you have a car, then driving to Siviez works really well - you can be in to the "main" Verbier ski areas such as Tortin, Mont Fort etc before they can get there from Verbier itself
