An essential component of your layering system, this is our most technical fleece full-zip hoody. Breathable, durable, and soft, the fleece’s innovative hollow-core fibre construction provides superior warmth for its weight. Patterned for ergonomic freedom and fit for easy layering under a shell, the Delta also shines as a standalone warming layer at camp or on the move. Size and fit tip: The Deltas offer a roomier fit in the body and sleeves than their predecessors, for improved comfort, versatility, and freedom of movement during high-output activities.
