“I think one of my absolute essential pieces would be a good non-waterproof trail running shoe like the Salomon Speedcross. The number of muddy take-outs these have prevented - saving me and my friends from slipping back into the water - is countless. Being able to trust that you will be able to keep traction on any surface is priceless.
“My most used and loved piece of kit has to be my Rab Nucleus Pull-On Fleece. It’s amazing wherever, however and whatever I use it for. It’s a really warm but breathable layer under my drysuit that doesn’t get in the way, but it also works brilliantly as a day-to-day fleece; plus, it comes in some really nice colours!
“I think some other out-and-out essentials would include a first aid kit from Lifesystems, which come in a range of different sizes including one which is waterproof. They’re very well-organised inside, unlike others I’ve used in the past which are often loosely filled.
“I also get really good use out of Icebreaker base layers on long expeditions. They don’t develop a smell anywhere near as quickly as others and they keep you warm even when wet.
“Other great bits that are often forgotten: energy bars, whistles, a good headtorch – such as Petzl or Black Diamond which are also waterproof - and you can never have too many dry bags (try Osprey or Exped). I divide all my kit up into different coloured and sized ones to make it easier for me to find something or point someone else in the right direction if I’m busy instructing.”
