Hydration
426 productsThe basic decision is a bottle or a bladder with a tube.
With a bottle, you can keep track of how much you have drunk and it is easier to fill; from a reservoir, you drink while walking, so you drink more often — and on a long trail, this is more important than it sounds. In winter, the tube has a disadvantage: it freezes if you do not blow the water back after drinking. Where you do not have a reliable source of drinking water, sort out water treatment: a filter, chemicals or boiling. Do not automatically assume water from streams and lakes is clean, even high in the mountains; there might be a pasture above you.

Expert advice
Our gear specialists are here for you. We offer tailored advice for any adventure.
Contact an expertFAQs
Use a three-layer system: 1) base layer (wicks away sweat), 2) mid layer (thermal insulation, fleece), 3) outer layer (waterproof and windproof membrane).
Follow the size chart with specific measurements. Functional clothing should fit comfortably and allow for free movement; insulating layers can fit more snugly.
Merino wool, technical synthetics (polyester/nylon), and membranes like Gore-Tex® offer the best performance, moisture wicking, and durability.
Wash on a gentle cycle with a detergent for sports clothing. Avoid fabric conditioner. Air dry and occasionally renew the water-repellent (DWR) treatment.
Premium membranes like Gore-Tex offer a higher hydrostatic head and durability, while cheaper alternatives focus more on breathability or low weight.
