@Lanzastar Is this pad for car camping or backpacking? If for backpacking, you want as small and light as possible. For car camping, weight is not as important, but excessive bulkiness should be avoided.
I have never needed a pad wider than my bag, but your mileage may vary. Still, I don't think the wider pad is necessary. The R value of your pad is probably much more important.
one or more gifts or other benefits from the co-op.
