The Microlight Vest is such a versatile & practical addition to your kit wardrobe; it provides essential body core insulation, allows unrestricted movement, reduces bulky layering, weighs next to nothing & packs down teeny tiny. This deservedly extremely popular Vest is stuffed with 80g of 750 fill power Hydrophobic European Goose Down all wrapped up in a durable & breathable Pertex Microlight shell. Rab is using Hydrophobic down in all their down clothing, basically each & every cluster of down is treated with Nikwax products to make them perform better in damp conditions. Although Hydrophobic down is not waterproof it dries much faster, absorbs less water & retains loft far better than untreated down. This is such a versatile bit of kit, providing fantastic levels of warmth & comfort to core body areas & packs down into its own chest pocket to take up virtually no room in your pack when not required.
