Eira Nightcap Parka - Men's: There are two definitions of a Night Cap. One is a beanie or toque-like cap worn to bed to keep you warm & cozy. The other is a stiff drink taken right before bed, which also keeps you warm & cozy. Eira’s Nightcap parka is two inches longer than our standard length jacket, which might also keep you warm & cozy. It has the same technical features as the Loyalty & Fortune jackets, which place strong emphasis on re-cycled materials.
