Freetime synthetic Micropak sleeping bags are made using a specific filling: 4T Staple fiber.
Its structure offers many advantages:
It shows a very good insulation/weight ratio.
It has a remarkable compression capacity.
The fabric is more porous therefore perspiration is easily evacuated.
This is how we can reach performing sleeping bags with great figures: our summer sleeping bag Micropak 600 weighs only 590g, and its comfortable size—210cm length and 78cm shoulder-width—can be compacted in a 28cm x 14cm stuff sack (4.3l). For colder nights, our Micropak 1200 weighs only 1250g for generous dimensions—220cm length and 80cm soulder-width—can be compressed in a 38cm x 19cm stuff sack (10.8l).
