  • Going to Everest Base Camp in about a year and do a bit of winter stuff up here in Scotland. Grappling with choosing a sleeping bag that's comfortable to -13 or so. Seems that nothing synthetic matches down in terms of weight/warmth/pack size... although they do have the waterproofiness advantage.

    Any one have any suggestions for something non-down? I might try to get a second-hand down one otherwise.

    Edit: how ethical is ethical down? Am I better with natural/biodegradable down than synthetic stuff produced from oil? Apparently down has a lower carbon footprint? And so on... Just looking for random opinions basically.

  • This is the sort of thing I struggle with. Usually for me it’s wool. Is it more ethical to but something made from petrochemicals or an eco alternative (bamboo or hemp or something) that’s been shipped halfway around the world.

  • A lot of the food you buy is shipped halfway around the world, and yet transportation still only accounts for around 3% of the total emissions from the product. It’s less for items that doesn’t need cooling, so it is thoughtful, but not relevant to take into consideration.

    My organization recently funded a project, that clearly showed that hemp was the most sustainable choice, based on both emissions, pesticide, energy and water use etc.
