I’ve had my Q350 for around 7+ years now for backpacking & bikepacking in Lakes/Scotland, plus some bivis. Generally, at anything above 5C, its like wearing a furnace! Even at -5C its been great. In warmer temperatures, I usually have to unzip the bag and have it like a quilt, but it’s great to have that bit extra when it cools down. The down is resilient and just beautiful quality. I’m 180cm and 86kg, so its a bit snug, but not tight. It would be nice to see a Long version, but then that adds weight to the current 700gm. I use a Nemo Tensor insulated mat (R=4.5) and the combination therefore feels like 10/10 for comfort, quality and warmth.

Really impressed with this bag. I’ve owned down bags from pretty much all of the big UK brands so wasn’t quite sure what to expect from the quantum 350 as up to delivery had not actually seen one in the flesh so to speak. The shell feels really durable and high quality also the zip was much beefier than I expected given the weight of the bag. Temperature rating wise for me being a warm sleeper if well-fed could easily manage minus 10 with this and base layers have used it at minus 5 with just a light t-shirt on and was toasty warm. All in all highly recommended if I was pushed to pick a fault I can’t with the bag itself but the mesh storage bag although quite funky looking in my honest opinion I would compress it a little more than I’d be happy with it but I’ve always stored my bags loose so it’s not an issue for me

This bag is a simple no-frills lightweight packable sleeping system. On that front it’s awesome. I do think the -6 is way too optimistic though; I’ve used this bag in various conditions but never want to go down below 0 degrees Celcius as this is when I begin to feel cold spots even with a liner.
I have used the bag in British winter and most recently Iceland, it has become my go-to bag most of the year due to its packability; for bike-packing, this is a huge positive
It’s also a very snug fit- I’m 6ft and no very wide and there isn’t much wiggle room once I’m in.
The biggest plus was the price compared to similar bags when I purchased it.
