Looking for recommendations for outdoor gear for Irish winter conditions, around -5°C to +5°C, including rain and strong winds. It’ll be used for wild camping, trekking and rock climbing.
I’d like gear that’s durable, lightweight and versatile across all three activities. Where possible, please focus on the following companies:

Mammut
Nemo
Arc’teryx
Petzl
La Sportiva
Scarpa
Rab
Black Diamond
Merrell

What would you recommend?
