Spire models feature the Robens standard 195cm body length. The range uses synthetic insulation with a two-layer construction. A PFC-free lining improves moisture transportation and heat loss is minimised by a zip baffle over the anti-snag two-way YKK zip and the oversize contoured thermocollar. This works with the fully insulated hood to create a snug fit for colder conditions. A shark fin foot improves sleep comfort.
