Do you prefer canvas or synthetic rugs?
Do you prefer to buy one really warm rug or get a medium weight rug and then a polar fleece or woolen rug for underneath, or two lighter weight waterproof rugs. It gets down to about -5 degrees celsius (23F) here at the cold end in winter (sometimes as low as -8 C:17 F) with most nights being atleast 0 degrees (32F). I'm leaning towards a mid weight synthetic with a woollen under rug. Another climatic factor is that we have been in drought so not much rain but this year may be more rain as we have already had a period of 4 days where it rained (light-medium) almost constantly.
