Their most technical fleece midlayer jacket delivers performance that transcends cozy. Breathable, durable, and soft, the fleece’s innovative hollow-core fibre construction provides superior warmth for its weight. The smooth face adds durability, and Phasic AR II panels under the arms add stretch and are made with wicking fibres. 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.
