Hyke & Byke Snowmass -15 Degree C Down Sleeping Bag with ClusterLoft Base for Backpacking, Ultralight Mummy Down Bag with Lightweight Compression Sack and Five (5) Color Options

I slept in this during the week for 14months straight. I was in a small tent in the UK. I experienced snow, rain, winds and a balmy summer - typical of English weather. The bag performed really very well - I was always warm enough and had some of the best sleeps of my life. It did get wet/damp a couple of times but easily dried out. Zip always worked fine. Not one fault.

Haven't used it yet apart from checking I fit in it, I'm 6'2" and the large bag has more room than many other I've had. Repacking into the stuff sack is awkward I'll need a few practices before I try this out on a mountain side. Can't fault it for quality. I'll update in a few weeks if I get a chance to escape the city for a few nights.** quick update, first use went well the sleeping bag is perfect for me. I've thrown the stuff sac/compression bag in the bin. it takes way too long to get it in there I've substituted a large lightweight dry bag for it. dry bag takes 30 seconds to fill, another 30 seconds to get all the air out and it packs smaller than the compression bag.

I got the bag back in June of 2018 and only used it twice over the last week as it was not cold enough (October 2018) once in a bivi and once in a tent, I found the bive compressed the bag and stopped it from lofting so it was not as warm as it could be, last night I was in my tent and it dipped to about -3c -10c with the wind chill and the bag keep me nice and warm I only wore a pair of shorts, the outside of the tent was covered in forest in the morning. I am 196cm tall and 90kg and got the large bag and have plenty of room I can completely seal myself in and still haveroom to move.The only issue I have with the bag is the stitching is fairly poor quality in some parts and is starting to freay only after using it twice like all sleeping bags I store it out of it's stuff sack.

Just received this sleeping bag and omg! The quality is amazing I never do reviews but this really does deserve one! I’m doing a hammock snow camp with the temp below zero at the weekend so I’ll be sure to update this review!

I bought this and used it for a night in the open on a charity rough sleep. Temp outside was 0C and I had a thermal base mat. I also had some decent thermal vest and bottoms on and I was still cold. This is supposed to be rated to -10C and I didn’t really feel that it was doing the job. I think this is an autumn and spring bag but not sure if I can endorse this as a Winter bag. Hope this helps.

Have only had the sleeping bag for a short while and used it on one occasion. It is brilliant and really does everything as promised giving me four nights of really refreshing sleep keeping me very comfortable The service provided by the company is first class and they present as very committed to ensuring you are supported and advised appropriately. I am really looking forward to using my bag again knowing I will be warm dry and have a refreshing nights sleep which will ensure I get the best from my trips

This is a decent sleeping bag. Used camping at a reasonable altitude up in the Highlands, down to sub 5 degrees. Very comfortable. Only 4 stars because, compared to my other down bag (which isn't quite as warm), it is much bigger, even when the compression bag straps are tightened as much as they will go.

Refusing to pay premium rates for popular names, such as RAB or Robens, I took a risk and purchased this for family and solo wild-Camping.I was glad I did.Incredibly warm, well-designed and easy to pack, this has been up there with my best outdoor purchases and, once my sons are old enough, they will have these as well to accompany our adventures in Britain’s great outdoors.These are guaranteed to become more popular over the next few years, so cash-in now before supply and demand hits the price!
