I live in northern Sweden and it gets cold here in the winter, from late October to late March we have between -20 to -35 celsius. So cold that your spit freezes to ice before it hits the ground, so camping in these conditions is a bit challenging with a tent and a sleeping bag.
So just the sleeping system weighs almost 10kg.
to be able to sleep comfortably in these temperatures in these icy winds, you need everything in L and XL. In my case, a British Army Modular Winter Sleeping Bag, on the inside of that, a British Army Arctic Sleeping Bag, and on the inside of that, a Fleece Sleeping Bag Liner. And the sleeping system inside a large water and windproof U.S. Style MVP Bivi Bag. And that whole sleeping system, without separating it, goes down into an Austrian 2 Strap Duffle Bag for storage.
I have had similar sleeping systems for over 20 years and they work perfectly in all weathers and seasons, summer and winter, you just take from or add parts as needed. In the middle of summer I only use the Fleece Sleeping Bag Liner and the MVP Bivi Bag, and in the winter, the whole system, allows me to throw the system directly on the ice in blizzards down to -35, zip it up and sleep like a peaceful lamb all night.
This year it was time for a new one. so when I found GOarmy uk with great prices and excellent customer service, I jumped at the chance and bought a whole new set. And everything only cost me 400€ with the shipment, the customs freight and other things. To be honest, this I bought from Goarmy is probably the cheapest system I've ever bought. I bought one 4 years ago, when I gave my son my old system when he was going Scout winter camping. I paid almost €1600 for the new system then. This year my wife wants to go with me and the kids and winter camping and ice fishing in the mountains, so she gets my system, and now I bought this on GOarmy for only 400€. From now on, I will only shop here at GOarmy. Cheap, good quality and super good support.
Thank you GOarmy
