Conceived for expeditions in extremely cold environments, the Solar Flare won't let you down when the thermometer drops. Premium quality 800-fill European goose down provides optimum compressibility and warmth-to-weight, while the use of Polarguard 3D insulation in high compression areas maximizes support and thermal efficiency - and utilizes a durable Shadowlite HyVent shell to provide an effective barrier against water penetration. Available in right hand zip only.
