Experiment 355 - Acottonflannel Warmshirt

An extremely breathable lightweight insulation system with a soft cotton exterior and beautiful merino interior. Albini Acottonflannel on the outside, super breathable Alpha 60 insulation in the middle and a soft and dry nylon-core merino on the inside.

Alpha is a non-migrating insulation originally designed for US special forces and optimized for breathability and wet conditions performance. It can be paired with a much more breathable face and lining fabrics than almost any other common insulation, which in turn allows us to create much more comfortable cool weather clothing. The nylon-core merino interior keeps things soft and dry with all of the natural performance of merino. On the outside is Acottonflannel, a 100% cotton 190gsm plaid flannel woven and spun in Italy by the masters at Albini, because no one quite does shirting like they do. Like most [alpha]core set-ups this combination traps a nice amount of warmth but begins to dump heat before things get too hot.
