Hwyl takes its name from a Welsh word that has no direct English equivalent - something between fervour and the state of feeling fully alive. Aesop named it after the emotion you might feel standing in an old-growth forest at altitude, which is also what it smells like.
The composition is built around hinoki cypress oil, a rare ingredient extracted from the Japanese white cypress. Hinoki has a quality that most wood-based fragrances approximate and fail at: it smells genuinely cold and resinous and alive, not like a cosmetic interpretation of the outdoors. The opening is sharp and slightly medicinal, which some people find off-putting and others find immediately addictive. The dry-down settles into something richer - there is vetiver and patchouli in the base, but neither dominates. The result is a fragrance that reads as outdoors without reading as sport.
Aesop’s bottle design is consistent across their range - amber glass with minimal labelling - which means it looks composed on a shelf. The 50ml size lasts a reasonable amount of time given how dry the sillage projects.
This is a fragrance for people who find most commercial perfumes too sweet or too loud. It wears close to skin and rewards proximity.
