PipeDream 200

Crazily I bought my Alpkit Pipedream 200 for £109 2 years ago (with a £10 discount and it might have been on sale)... and the current sale price for it is £189. I do like it as a summer bag. I've also got a cheap ali express down quilt, which packs even smaller. I don't get much use out of it though as I'm not a massive fan on quilts and it is often a bit cold for it.

I’ve got an alp kit pipedream and that’s great for most of the year. I use it zipped up and wear base layers in winter, then in summer I open it up and use it as a duvet. I’d much rather be too hot that too cold

The Alpkit Pipedream is excellent. If your budget allows, go for this option.

Alpkit down sleeping bag. Best bet for down bags, used mine 3 years and has been perfect

I'll just mention that my snugpak 'winter' bag is rated to -10C, but there's no way I'd use it in those temperatures. Take the rating with a pinch of salt. My Alpkit down bag (-7C comfort rating) is way warmer than the Snugpak. I don't know about the arctic bag, I have the modular system. And yes, get a decent mat.
