Pure Blue Japan Indigo Check Flannel Workshirt (Indigo X Red)

Size Guide
Some of the softest flannels we’ve seen!

Of course, PBJ always specially develop some amazing products for us to enjoy! This flannel fabric is actually thread dyed then woven rather than over-dyed. With time, you’ll see many more shades of colour making up for a soulful faded look.

The indigo threads have been rope dyed, meaning each fibre has many levels of indigo that will reveal themselves with time.

When you feel this one in person you’ll be shocked how soft it really is! The outer surface has been brushed, typically this is on the inside but PBJ are bringing out the softness! This one is as comfy as your favourite blanket, no doubt.

With two asymmetrical chest pockets, you can easily carry your phone and keys with you!

If you’re after a classic styled flannel with the beauty of indigo ageing and a more functional pocket design, this is it!
