“I arrived in Finland a few days ago and I have survived my second Russian winter, thanks in no small part to the Main Range. The sleeping bag has been brilliant!” 
Mont Ambassador Benji Rogers-Wilson, Earth Odyssey


”Once again I used Mont down products on this expedition and they were awesome. I have the new Mont Main Range sleeping bag and it was comfortable even at the high camp of 6000m. Temperatures got down to around minus 20-25 degrees at night but I often actually couldn’t zip the bag up as I was too warm in it when I wore my thermals inside!” 
Mont Ambassador Allie Pepper after her ascent of Mount Aconcagua

“At the end of a 35 below day on the Antarctic plateau I always look forward to a few luxuries; a bowl of chicken curry, Sigur Rós on the iPod and my Mont sleeping bag. It doesn’t matter where I am in Antarctica, among the coastal mountains or up at the South Pole, my Main Range is with me. It’s more than just a luxury, it’s a necessity.”
Mont Ambassador Eric Philips, Icetrek
