Bark n Bag adds the Old World Traveler Collection to its line of eco-friendly pet carriers and totes. The fabric is a polyester fiber made from recycled plastic bottles. The carrier gets its support from bamboo rafters and its comfort from organic cotton padding, the company reports. The carriers are available in three sizes and can accommodate pets up to 22 lb., according to the company. They have three points of entry, mesh ventilation panels, a removable padded shoulder strap, a padded handle grip and two zippered pockets. The ventilated totes are available in two sizes and can accommodate pets up to 16 lb., the company adds.
