Quilts Remove The Insulation That Never Worked
Quilts and open-back systems grow at 6.9% against 4.6% for the market on a genuine physical argument rather than a fashion. Insulation compressed beneath a sleeping body loses almost all its loft and therefore almost all its warmth, so the fill underneath is weight carried for nothing. Removing it saves between 15% and 25% of total mass at equivalent warmth. The trade is draught management, which requires more care in setup and suits experienced users considerably better than beginners. That is why the format has grown fastest among people who walk furthest. Beginners still buy conventional bags, probably rightly.
Market Impact: China grows at 7.8% annually
