MT900 50°F/10°C

I have Decathlon’s down sleeping bag, which is quite a mummy bag. I had the same concerns as you, as I tend to roll around a lot and sleep in different positions. I’m finding I really like the bag. If I roll around I tend just to roll with the bag. It doesn’t bother me at all how tapered it is.

I’ve just finished the WHW yesterday and managed to get everything I needed for around that budget. Here’s what I went for, hopefully it’s helpful. You can pick up a second hand Osprey rucksack for less than £100. I got a 48 litre Kestrel for £60 on Vinted. The Exos is slightly lighter. I found it was selling in the £80-90 range on eBay. I used a Naturehike Cloud Up 2 tent which a friend let me have (he’d also used it for WHW). For the price (currently £140 for upgraded version on Amazon, you might find it cheaper elsewhere) you’ll find it hard to find anything lighter with the same amount of space (it’s 1.7kg including pegs). It’s really easy to put up, there’s loads of videos of YouTube to help you. I got a Mountain Equipment Helium 3.8 mat for £35 second hand off eBay. It’s 750g. There are lighter mats out there but you’d be doing well to get one that’s less than 500g with an equivalent R-rating for less than £100 second hand. (The R-rating is how well insulated the mat is, you’ll probably want one above 3). My sleeping bag was the hardest thing for me to pick since there are so many options. In the end I opted for a down sleeping bag from Decathlon (MT900) with a comfort temperature of 0 degrees Celsius. It weighs 880g in my size (M). I got it new off a seller on eBay for £110. It’s £170 on Decathlon website. In terms of shoes, if you have a good pair of boots that you know are comfortable, waterproof and don’t give you blisters, stick with those. Especially if you’re on a budget. I chose trail running shoes because I’m also a runner, so I’m able to use them for trail running as well.

I'm from Europe too, I usually look for Decathlon or Naturehike, those two I've tested them and they respect the temperature written, at least in Italy decathlon is the best price/quality ratio

It depends, mainly Forclaz,
