The Robens Serac 300 Sleeping Bag boasts a standard mummy profile and an RDS-certified 300g down filling for the best warmth to weight comfort ratio on most general outdoor adventures. The down filling is also highly compressible so can easily be packed away in its compression stuff stack when not in use, and is highly lightweight so won't weigh you down as you move. A neck baffle additionally minimises heat loss, while a shark fin foot box with extra insulation will provide optimum warmth to where it is needed, alongside allowing your feet to rest comfortably in a natural position. To finish, the durable riptop outer fabric is highly durable and tear resistant, and the lining offers a high moisture transport.
