To a great extent, the ultra heavy flannel (UHF) shirts very much defines Iron Heart: heavy, rugged, but amazingly wearable.
The 12oz fabric is woven with Aspero cotton from the foothills of the Andes mountains. Double brushed on the inside and single brush it on the outside, resulting in a very soft yet substantial, thick, warm and windproof flannel. This shirt is a wardrobe staple—seen here in our western cut with a red American check.
News is that due to the use of a reactive dyeing process for the UHF fabrics—as opposed to the direct dye technique used on older variations—this plaid features a subtler colour palette compared to the vibrant checks from previous seasons.
Whereas those older direct-dyed fabrics would mellow in appearance after a few washes, this new dyeing method is far more colourfast. To counter this, IH muted the colours slightly to offer a more worn-in appearance from the get-go.
