Quick answer: an insulated stainless-steel bottle keeps water cold on hot hikes and drinks hot on winter trails. For hiking, a 600 ml–1 litre bottle with a leak-proof lid, a wide mouth for ice and cleaning and a weight under about 450 g is ideal. Hydro Flask, Stanley, YETI and Klean Kanteen are proven brands. On longer hikes where weight matters, carry an insulated bottle for drinks and lighter plastic bottles for the rest of your water.

Insulated vs plastic bottles
Insulated bottles are heavier but keep drinks at temperature for many hours. Lightweight plastic bottles (such as Smartwater bottles or Nalgenes) are lighter and fit water filters. For ultralight trips, many hikers skip insulated bottles altogether except in winter.
