The aim with the Mountain Raid was to design the bag which we would want to use when running on the OMM or other events/activities where weight vs performance was critical. We wanted it to be warm enough for use, light, have good performance in the lovely UK weather and compact.
The bag designed 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, full footbox with external hangtags to dry/air and cowled hood. Also it features a offset 1/4 zip with again a P1 isulated baffle to protect aginst a cold zipWe found that this combination offered an active Mountain Marathon racer the right perfomance for the OMM, gave a windproof bag for emergencies and a system that would provide a insulative value when both wet or dry (packing accidents do happen). It will be in the shops in October '12.
