Byredo Alto Astral
- Authentic original perfume
- Try before the full bottle
- Travel-ready 3ml, 10ml, 30ml
- Long-lasting scent
Alto Astral by Byredo opens with aldehydes and coconut water, a fizzy, faintly milky freshness. From there it moves straight into a warm, woody base of amber, cashmeran and sandalwood, smooth rather than sweet. New for 2025, it is worn by men and women alike, anyone who wants a fresh opening that settles into something calmer. Voters wear it across summer and spring, from day into evening and night, which makes it flexible rather than tied to one moment. The longevity vote leans long-lasting. Most wearers call its sillage moderate, keeping it fairly close rather than loud. A 10ml decant is enough to live with it through a season and decide if it earns a place on your shelf.
