This rucksack is a large version of the medium rucksack. It is longer by at least 20 cm and wider by 5cm. It's designed to carry a lot more items needed for either winter or just because you need more room. It has enough room to carry a wetsuit, towel, flask, cups, gloves, bootees, hat, extra clothing, just stuff it down. This lovely, practical oilcloth fabric in a soft matt grey background with white flowers  can be wiped down to keep  it clean.  It has adjustable extra long contrasting brown straps , mainly so you can get them over a dry robe. The bag is closed and secured against the weather by a webbing strap that is secured with a sturdy clip. You just stuff everything in, turn the top of the bag over twice and clip into place.
 
The soft mink coloured lining is made  from a strong water resistant pvc. If you are carrying damp or wet items it is designed to be pulled out after each outing to dry out. If it gets a bit dirty, just wipe it over with a cloth. I have waterproofed all of the seams on the lining, that way it will keep everything inside dry, or if things are wet inside, that will be kept away from the outside shell.
 
This bag is available in a number of fabrics, It  can take up to 7 days for me to make and send it out.
