The aim with the Mountain Raid was to design a bag which you would want to use when running on the OMM or other events/activities where weight vs. performance was critical. OMM wanted it to be warm enough for practical use, lightweight, have good performance and be compact.
It is the purist bag for the minimalist with Primaloft One® PL1 and Pertex Quantum a winners combination. The bag weighs 400g and stuff's down to the size of a Grapefruit, combining loose laid Pertex Quantum over 60g Primaloft One synthetic insulation on top and 40g Primaloft One synthetic insulation on the bottom, it features a full foot box with external hangtags to dry/air and has a cowled hood to keep your head warm with a offset 1/4 zip with again a P1 insulated baffle to protect against cold.
The bag also doubles up as a safety/emergency bag to carry with you at all times on the Mountains and in the Wilderness.
