Egyptian long-staple cotton is among the world's finest — long fibres produce softer, more durable fabric than standard cotton. Heritage suppliers include Cotton Egypt Association-certified mills in the Nile Delta region. Buy at: Shahira Mehrez (Zamalek heritage Egyptian cotton boutique), the Egyptian Cotton Boutique at the Four Seasons Cairo, Khan el-Khalili souk (negotiate prices, verify the Cotton Egypt logo), or international export through Frette, Sferra, Pratesi (the high-end European linen makers source Egyptian cotton). Egyptian cotton bedding ($300-1000 USD for a queen-size set in souk; $1500-5000 USD international retail).
Visitors typically use bottled water — Cairo tap is technically potable for residents accustomed to it but the chlorine and mineral content can cause stomach issues for unaccustomed visitors. Bottled water (Aquafina, Baraka, Hayat) is ubiquitous and inexpensive (5-10 EGP per 1.5L bottle, ~$0.10-0.20 USD). Pack: an insulated reusable bottle (Hydro Flask, Yeti) — refill with bottled water for cold-water-on-demand throughout the day. Skip ice in drinks at less-recognized restaurants; recognized hotel bars (Four Seasons, Sofitel, Marriott Mena House) use filtered ice.
