Criterion Quantum 200 sleeping bag – 530g

Criterion Quantum 200 sleeping bag – 530g

If you’ve had the fortune/misfortune to gain entry into one of the big winter ultramarathons that the UK has to offer, one of things you will get to know really well is kit. Lots of it! 

For my winter Spine adventure I had the unenviable job of buying all of my mandatory kit in the lead up to the end of the year. This was partly due to spreading the cost of the big items on the 31 item kit list, and partly because I spent way too much time on the forums reading all the kit reviews of all the items I needed, without making a decision on what to get until the last minute! 

One of the major bits of kit I needed was a sleeping bag. Not just any sleeping bag mind you. Nobody wants to be dragging a 1kg bulky sleeping bag up 268 miles of the Pennine Way at the best of times, let alone in the middle of winter when you have to carry so much else as well. 

What I needed, according to the strict guidelines set out by the Spine race, was a sleeping bag that was rated to 0 degrees.

This means that if the worst should happen and I faced a cold wait out in the open, I would be snuggled up in my warm sleeping bag and bivvy bag, nice and warm while I awaited mountain rescue.

Fortunately for me this need didn’t arise during my race (despite having a bit of a nasty tumble in the early hours of my 5th day of running). I did however still get to test out my chosen sleeping bag. The Criterion Quantum 200. 

The test came late in the race at the final checkpoint at Bellingham. 

Anyone who’s ever completed the winter Spine race knows that this checkpoint, despite its warm welcome by the volunteers is actually the coldest checkpoint to stay in. All of the others offer at least a bunk bed in a dormitory, some even offer an actual bed complete with sheets!

The Sleep Test

Bellingham however, just has a solitary cold and draughty hall. Add to this the fact that the outside temperature during the night had been -7 in the valleys and upwards of -15 on the hills. You can imagine the kind of temperature we were dealing with even inside. 

I wanted to grab one last chance to ‘sleep’ here before the final push over the Cheviot hills to the finish. So I decided to take advantage of the opportunity given to bed down. I rolled out my inflatable air mat and pulled out my Quantum 200 sleeping bag from its stuff sack. 

At around 500g I was slightly concerned that something so small and light could be warm enough to keep out the chill of the cold and damp January night. But to my surprise, it did just that!

As I shuffled down into the bag I could instantly feel it trapping the heat from my body. I pulled up the zip that snuggly encased my body like Tutankhamen in his sarcophagus and wriggled around to get comfortable. For something so light I was amazed at how quickly I warmed up. In fact it was so warm, I had to unzip it and take off my T-shirt to stop me from sweating. 

I had about an hour of sleep before I decided I needed to get moving again and repacked all of my kit. As before, even in my tired and disoriented state I managed to pack the bag back into its small stuff sack. It dropped neatly back into my pack and I continued with my journey. 

I would definitely recommend this sleeping bag to anyone taking on a winter adventure. If you feel the cold on summer expeditions then this will keep you super toasty, maybe even a bit too warm. The warmth to weight ratio is ideal for someone who wants the performance of a top end bag, but without the weight of a thicker more insulated one or having to pay the earth to get it in a lighter bag.

It is made using a Pertex Quantum (35gms/m²) ripstop shell filled with 200g of 850 FP Polish Goose down. Boxwall construction helps keep the weight down to a minimum.

A DWR treatment of the shell helps protect the down from any dampness that may occur, from condensation or wet gear. 

At £300 it’s at the higher end of the price point for this temperature rated bag, but some brands charge a lot more for very little in weight saving. If you want to be warm, safe and travel light then £300 is reasonable. 

Additionally, they are a British made brand and their customer service is second to none. I fired off a couple of questions via instagram DM and got an almost instant reply from Gareth who looks after the business, whilst he was out walking his dog! 

If you want a top quality lightweight sleeping bag that passes the strictest of kit checks, for a price that doesn’t break the bank. Look no further than Criterion Sleeping bags.
