6 Pack Fitness has now unveiled the bag it started teasing at the start of the week, and as promised it is one of the two it had on sale at the Olympia Expo. The product due to be officially released next by the brand is the Contender, which is a combination of a meal management system and a general backpack. As you can see in the image above, 6 Pack’s Contender includes a cooler big enough for a single meal as well as a main compartment for everything else. According to the brand the Contender Backpack is set to go on sale this Friday through its website, with stock expected to sell out fast.
