Y’2 Leather IN-1 Deck Jacket – Indigo Horsehide


The IN-1 Indigo Horsehide deck jacket is quite simply your freezing cold armageddon ready jacket. It is a beast and a luxury one at that. It’s quite something.

There is so much to describe:

  • Soft and rich in depth hand dyed Indigo 1.3mm horsehide
  • Very heavy duty Black Universal 2 way zipper (great for bikers and easy access
  • Soft Mouton collar
  • Soft non scratchy long-fur alpaca and wool lining
  • Elasticated internal storm cuffs

The leather is beautiful, heavy weight but butter soft and very pliable horsehide (easy to move in). It is quite the feat to apply natural indigo dye to leather and by doing so it gives such a lovely depth of colour (which is really hard to capture in images, the colour is more like the darker worn images overall). On a jacket this is some of the nicest and most plush leather we have felt. Lovely.

The lining is so warm, soft and comfortable it will easily protect you from the worst of weather in absolute comfort. The details are plenty. Internal elasticated storm cuffs, reinforced stitching in areas of stress, 2 large outer hand warmer lined pockets, throat latch and a verty heavy duty universal 2 way zipper for access and comfort when sitting.

The finish, as is to be expected form a company that specialise in leather jackets from Japan, great. Very neat and all well aligned.

The IN-1 is a very well thought out and executed cold weather jacket and we don’t have a bad word to say about it.

Take a look at the measurements and sizing detail for fit information. Keep in mind the thicker lining when comparing measurements.

The IN-1 Deck jacket is slightly smaller in terms of western sizing. The model is wearing a size 42 for a good fit on the whole, maybe a little longer in the arms (but they wil crease up) but not restrictive or big. He could size down to a 4o if wearing just a normal weight short etc.. He generally takes a medium-large/ 16 / 38-40 in most Western sized tops, shirts and jackets. A large in most Japanese made gear.

He is 5ft 10-11″ tall (180 cm), medium build/ larger chest/ back, weighing in at roughly 84 KG.

Thicker leather jackets, particularly horsehide tend to crease up and shape the the wearer more permanently than softer thinner leathers so advice would be to always oversize slightly, similar to the model and it will shape to your body better without feeling restrictive. This horsehide although soft will shape up and therefore look slightly smaller after break in.

Please see how we measure our products here and compare the measurements chart for this item against an item of yours that fits how you would like this to. Bear in mind that a horsehide jacket less pliable and giving than many fabric or soft leather jackets you may own so for ease of movement you might want to go for the larger size if on the fence.
