Sorry, if i'm reposting, but i couldn't find it from HUKD search.
Just went through Price cuts and bought one of these from Argos.
# Lightweight polyester holdall 'D' shaped top zip opening and external front zip pocket.
# Webbing grip handles.
# Size (H)36, (W)94, (D)36cm / (H)14, (W)37, (D)14in.
# Weight 2.5kg.
# Capacity 121 litres.
Its a very large bag and really cheap at this price. 121 litres capacity is really helpful.
