This post is another in response to a question I’ve had: (Slightly Paraphrased)
“Do you really fit a weekends worth of wild camping gear in 5kg?”
The answer is Yes, I do. But before I go into details of what makes up the bulk of the 5kg, I should qualify things. Firstly, that 5kg is dry weight, so that doesn’t include water, food, or fuel. Secondly, that is the summer bag. In winter I use a heavier sleeping bag and a heavier bivvi bag, making my dry pack weight nearer 6.5kg.
The big three is a term coined by Ray Jardine. They make up the bulk of the weight of your pack. So what are they?
- Sleep system
In non ultra light hiking it’s easy to pile on the pounds with these three items. Before I started aggressively lightening my pack the big three were:
- Backpack – Berghaus Vulcan + PLCE Side pockets – 3.2kg 110L
- Sleep system – Snugpak SF 2 sleeping bag + Highlander self inflating sleep matt – 3kg
- Shelter – Vaude Hogan – 2.9kg
You can see that these three items alone are over 9kg. Having 110L of backpack then encourages you to take more stuff, after all you’ve got the space in your pack… This resulted in my lugging 25-30kg backpacks round Europe on various trips before I decided that there had to be an easier way of doing it.
So what are my current big three?
- Backpack – Osprey Tempest 30 – 0.85kg
- Sleep System – Mountain Equipment Lamina 35 sleeping bag (1.02kg), Exped Synmat 7UL (439g) – 1.459kg
- Shelter – AMK SOL Escape Bivvi (240g), Miltec Flecktarn plane tarp(543g inc pegs + guys) – 0.783kg
Those of you good at mental arithmetic will be able to quickly sum that the total for the big three is 3.092kg. Giving me around 2kg for all the other bits an pieces.
I mentioned before that this is my summer bag. What changes in winter?
- Sleep system – Mountain Hardware Laminina 20 – 1.55kg
- Shelter – British Army XL Goretex bivvi bag ~0.9kg
This adds 1.3kg on to the weight of the summer bag. The only reason I change bivvi bag is because the AMK SOL Escape bivvi bag is a bit tight on the hips, causing compression of the loft, resulting in cold spots. I am thinking of getting an Alpkit Hunka XL for next winter, saving me about 400g.
So you can see, a simple yet light big three, with the best part being that the most expensive single item was the sleeping bag (£93 for the Laminina 20, and £85 for the Lamina 35). Going ultra light doesn’t need to be that expensive.
