In reply to Jim Walton:
I'll add that the Spotty Otter gear is very hard wearing, my 3 kids have used their Explorer jackets (waterproof down parks) as sledges on snow, ice and sand dunes. If we'd had more kids they would have lasted a couple more years as hand-me-downs easily.
The only downside is the non-adjustable hoods mean they probably aren't suitable for "Munro weather" as per the OPs request.
