Happy Customer

All was well with my purchase/delivery. Goods arrived promptly and without fuss. The packcover itself looks fine and is a good fit for my 75(ish) litre rucksack. Just for info it doesn't come with its own stuff sack but that's no problem to me as I will use a rubber band to pack it down to size
