Nike x Union Dunk Low “Argon” (DJ9649-400): the quiet blue from the Passport Pack

Nike x Union Dunk Low Argon DJ9649-400

Powder blue, a grid that looks like graph paper, and a swoosh you can half see through. Union LA’s take on the Nike Dunk Low doesn’t beg for attention, and that’s exactly why it works. This is the “Argon”, style code DJ9649-400, and out of the whole Union Passport Pack it’s the most lowkey of the three.

Quick context: Union dropped three Dunk Lows in 2022 under the Passport Pack name. Pistachio, Court Purple and this Argon. The first two are the loud siblings. Argon is the cool blue one, the colour that slides into your rotation easiest without forcing you to build a whole fit around it.

The grid is woven in, not printed on

What makes it is the build. The entire upper is ripstop with a grid pattern woven into the fabric, so that checker actually sits in the material instead of being printed over it. On top of that a translucent swoosh outlined in orange stitching, a bit of coral pushing back against all that blue. The little Union figure sits on the heel, and a yellow tab next to the swoosh breaks things up. The outsole is semi-transparent ice blue. Layer on layer, but nothing shouts.

Wearing it is simple. This is a sneaker for calm fits: grey or light denim, a black cargo, a hoodie that stays out of the colour conversation. Let the shoe carry the blue and keep the rest clean. Go loud against it and you lose the exact detail that makes it special.

Retail is done, this is resale territory

Worth knowing up front: this is a 2022 drop, long gone from Nike. You can’t cop it new anymore, so everything you’ll find is secondhand or through boutiques. On Solezilla there are currently more than a dozen listings for the Argon across resale and boutique shops. The cheapest sits around 144 euros, and the bulk lands somewhere between roughly 150 and 245 euros. One listing is parked way above the rest, near 630 euros, but that’s an outlier, not a benchmark. Plan around that first cluster.

One thing to flag: right now every listing is priced in euros, there are no separate GBP or USD offers on this one. So if you’re shopping from the UK or US, factor shipping and any import costs into that euro number before you decide. The Hypescore still reads ATOMIC, so interest hasn’t cooled, but because this is the quiet colourway the price stays fair next to the louder Dunks everyone wants at once. Not the kind of drop you panic-click.

Torn between the three Passport colours, or just checking whether your size sits under 150 euros somewhere? Line the shops up on Solezilla, compare the price per size and grab it from whoever’s sharpest. And if you want to look wider in the model, every Nike Dunk is listed with its live prices, so you can see at a glance where the heat sits and where the deals are.
