Both bath sheets and mega bath towels are available which are both very large. Reviews on all of them are positive.
Delivery fees vary depending on location and how many you buy. Eg. $9.95 for single towel, $11.95 for 4 pack.
Royal Splendour Bath Sheets seem to be the best pick as far as size and GSM but cost a little extra and only come in red.
shame there is no charcoal colour left…. good deal though
