Created for comfort and performance across a range of activities and output levels, Arcteryx's most technical fleece zip-front pullover 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, the Delta also shines as a standalone.
