The problem with summer alpine climbing is that you have have to be able to cover a huge range of temps and conditions, from very hot to very cold.
The kit that I choose depends on the route, which will dictate factors such as:
- Is it north or south facing (i.e. will I be in the sun or not).
- Is it a route I will move fast on, or a technical route that will involve long slow pitches and lots of time belaying.
- Does it involve an overnight bivi.
Typically for a single day route that doesn't involve a bivi I use:
- Merino base layers
- R1 hoody fleece
- Wind proof jacket (I use a Arcteryx Squamish Hoody which is amazing, but plenty of cheaper options).
- Softshell trousers - which kind depends on whether route is mixed or just rock (i.e. something light weight if just doing a rock route)
- Softshell jacket with hood - again which kind depends on whether route is mixed or just rock (i.e. something light weight (prob just my windproof above if just doing a rock route).
- A sythetic booster layer e.g. Patagonia Nano Puff or Arcteryx Atom Lt
- Very light weight emergency water proofs (I use a Montane Minimus jacket), hopefully they just stay in the pack so the lighter the better.
- Variety of gloves depending on route.
- Buff.
- Cat 4 sun glasses, + lip balm are essential.
- Lightweight pack around 25-30L
