The Alpha Shell Overshirt is a shirt from Alo, $298 at retail. Shell-fabric shacket. The Alpha family's mid-layer.
It reads casual without reading sloppy.
Tagged athleisure and rainy-day, and down for everyday, travel and weekends — those are the occasions the builder will actually put it in front of you for.
It has a collar, which means it needs somewhere for that collar to go — under a hoodie or a turtleneck it bunches, and the builder marks that pairing down for exactly this reason.
The rest of the fit
One garment per remaining slot, chosen the way the builder chooses: occasion overlap, formality that holds across the fit, warmth that agrees with itself, and the layering rules that stop a collar ending up under a hood. Head to toe with the Alpha Shell Overshirt: $1,312 at retail.
