Iv got a rab assent 700. It’s down so light weight and remarkably compact’able. Comes with its own stuff sack and a storage bag to keep safe and not damage the down filling. U can find them on eBay/ fb market for £150. Might sound expensive but they do go for double that brand new.

I have the rab ascent 700. I have comfortably taken it down to -5 in the cairngorms however that was march and a very still night wind chill can make -5 feel like -15. If you are planning on doing a lot of winter camping I would get the 900 if you are mostly doing fringe/summer I would stick with the 700. I do also have a sleeping bag liner which adds quite a bit of warmth and use a hot water bottle (sigg/nalgene bottle with hot water before bed). Other factors like tent size/inner material and pad and personal preferences will also factor in warmth. So just because I have used the bag at -5 doesn’t mean it will be warm enough for you. I would try to choose somewhere you can easily get back to car/somewhere warm in case things go wrong on your first trip and first time testing your gear. I often do this with new gear. You can camp around Loch Lomond at this time of year the restrictions only apply February -October and the restrictions are only certain sections (double check on the Loch Lomond and trossach national park page as I may be out of date)

Look second hand for your first set of good gear. My first down bag was the ascent 700 and it was sufficient for my hammock camps down to 0°. I got it second hand on eBay for £100 and in good condition. You'll hear this many times on this thread, but if you're putting money into anything, make it your mat and your bag (or under quilt if you hammock). No shame in getting second hand, you just have to keep an eye on eBay.

If you want one bag for all year use the 900 isn’t it. Way too warm for anything but winter. Especially as you sleep warm already. So the 700 makes more sense, even if you pair it with a very light quilt or extra warm clothes in mid winter to be sure you’re warm enough. Only personal testing will really tell you how it feels so it makes sense to carry an extra layer on your first trip with it.

It's comfort rated to -2. You might want to swap it for a warmer one or take additional warm stuff to sleep in (down socks, trousers, jacket etc). Make sure you have a warm enough mat as well. If using an inflated mat which does not have a high r rating then you can place a basic CCF mat on top of it to increase the insulation value

Hello! Probably beating a dead horse with this question. Off to Scottish highlands next week and picked up the Rab Ascent 700 but now wondering if I should have gone to the 900 instead. Not super sure on the route as I'm tagging along. I'm not that experienced with winter hiking so won't be going high up to camp. It was an expensive purchase for me so paired with a good mat and some layers will this be okay? The weather is not looking colder than -5 (used Ben Lomond summit as a reference, I know you can't camp in that area without a permit). I am hoping to use this as an all year bag and love how small the down packs down. But will go for the warmer one if needs be. I do sleep warm. Thank you for any advice!. UPDATE: Thank you all for your advice. I did go with the ascent 700 in the end and got a fleece liner. It worked great until my new Therma rest mat decided it was going to deflate itself. Camped in the Cairngorms around -6.

I saw these and think they are the replacement for the existing ascent range. A few disappointing things though which I found from the Rab website when comparing the previous models to these: 1. The previous Ascent range were made in the UK, these are now made in China 2. The overall percentage of recycled material used in these newer ones is less than the older models https://preview.redd.it/g5gdlmtjppkg1.jpeg?width=1170&format=pjpg&auto=webp&s=373502feb34b23a4049c739f27097a2f2fc7c61e

I'm 6'3" and 115kg. Have a look at RAB sleeping bags in long/wide. I have an Ascent in long/wide and its super roomy and plenty long.
