Perfect for wild camping in the UK
I love this sleeping bag. Quality is great, the zips are fantastic and never seem to get caught. This keeps me warm on nights as low as 0°C, it’s super lightweight and packs down very small into a dry bag. 100% recommend

Nice bag
This is the most money I've spent on a sleeping bag, and hopefully the last, first impressions are its comfortable and the square end is amazing compared to my old mummy bag, never had a down bag before and had no trouble falling a sleep in it and keeping warm, albeit in the front room. Watching g a film!. I can't see me having an issue when I camp in may

Sleeping seems great However...
Sleeping bag seems great overall. Didn't actually test it's capabilities. I did opt for the Medium as I thought that should be fine size for me. However I sent the Medium it back as it was a tad too small for me. I'm 5'11 for reference. I'm looking to buy the size Large instead when Amazon has other Prime day or some form of discount on the Sleeping bag.

Great bag at a good price!
The only grumble about this bag I have is that the title says it is a "mummy" sleeping bag but the pictures and the bag in person are a square bottom bag, which luckily I prefer! The fill is good and 650 is a decent amount of loft for a mid range down bag like this. It compacts down really small and does not add too much weight. It comes with a perforated large storage bag as well as the compact travel bag and the zippers and stitching are all spot on. The bag is waterproof with a hydrophobic surface that water runs off and the hood opening has a good added bit of insulation to keep the opening warm. I like that the bag has a bottom opening as I get a bit hot sleeping and it's good to be able to open the bottom to let some heat out. I haven't tested it camping yet but its pretty warm after spending 15 mins in it watching the telly and I would say that its a pretty solid 3 seasons bag!

DO NOT BUY THIS SLEEPING BAG!
There are several things to be aware of with this sleeping bag. Firstly it states that it is "Goose Down" in the product description , however on the bag itself it states "Duck Down" . Goose down is much superior to duck. Secondly the description states it is 910g in weight, however, the bag itself states 400g mine actually weighed 380g. This is due to the serious lack of down insulation in the bag panels which was so thin there were bands an inch thick that separating each and every panel down the bag. There is only the nylon shell of the bag between you and the cold air. Having spent some time winter camping I am experienced enough to know this bag is NOT a 3 to 4 season, you would be cold in this bag in the spring with just a few mm of nylon to keep you comfortable. I would go as far as saying that it is dangerous to describe this bag as a 3 to 4 season for the new or inexperienced outdoors enthusiast.

Warm but light
Lightweight sleeping bag. It feels quite nice and compacts really well so is easy to get back into the bag after use. All right for the milder weather lately, kept me quite warm on an overnight camp, but I would definitely not use it if it gets much colder as it isn't very thick and I don't think it would cope. The colour is nice. I think the sleeping bag would fit in my compact washing machine no problem so keeping clean isn't going to be an issue. I've had several items from this brand now and they are becoming one of my favourite camping companies.

Defective and refused to replace
Wish I could give it 0 starts. It looks its been returned, stuck in a washing machine and shipped back out. The down is clumpy and there’s patches where there’s none at all. I bought this as a gift for my partner and it was used for one night and he was cold. Even though the items defective Amazon refuses any sort of replacement or refund. Do not buy this item

Un sacco a pelo in piume estremamente leggero e confortevole. Chiuso nel sacco comprimibile è di dimensioni davvero minuscole. Testato a 10 gradi di temperatura vestiti leggeri è perfetto. Probabilmente regge i 4-5 gradi di temperatura e se ben coperti anche qualcosa meno.

Testuje od roku. Bardzo przyjemny produkt, jednak przy temperaturze ok 10 stopni mocno zmarzłam. Nie wiem czy faktycznie nadaje się na zimę

Used it upto 5 degrees Celsius and it keeps me warm. Only downside is that it gradually loses dawn. Finding it in my tent in the morning...
