Zero grams
The less you carry the less you have to 'hang' off your pack.
The easiest way to loose pack weight is to leave it behind. You don't just save a small percentage by getting a light alternative but you save the whole weight of that item. It's far easier than cutting off the edges of your maps.
So do you really need it?
- That chair kit? - NO
- Your multitool? - NO (when was the last time you absolutely needed something on it that you couldn't do with a lightweight knife or razor blade?
- A spare day's food? - NO (you could live on just water for an extra day if you need to)
- A pillow? - NO
- A Carabina? - NO While it may make you feel like you're on some epic adventure unless you plan on using it leave it at home.
- 20m of rope (para cord/spectra) - NO there are other ways to dry your washing unless you need to pack haul.
- Spare clothes? - NO one top and one pair of pants is enough.
- Your camp crocs (or shoes)? - NO barefoot is awesome.
So on your next overnight hike or epic multiday hike try leaving a few things at home. Apart from being lighter you will enjoy the simplification.
