PipeDream 400 Hydrophobic down sleeping bag
Ultra lightweight 3-season hydrophobic goosedown sleeping bag. Box wall construction with a -6ºC sleep limit and weighing just 865 g; ideal for moving fast and light or lining your winter bag
The PipeDream 400 has a box-wall construction to give a lightweight fine-tuned sleeping bag with the adventurous traveller in mind. Optimised with 750 fill power down to get the most warmth, yet weighing only 865 g. With no unnecessary features, this specialist bag uses 400 grams of 90/10 750+ fill power goose down and is suited to 3 season use or as a liner bag for winter trips.
The bag has a water resistant DWR coating so the odd drip of condensation or early morning dew won't ruin your bag’s insulation and the dark colour scheme absorbs heat from the sun - so if your down is unlucky enough to get wet, it will dry quicker.
Supplied with cotton storage bag and lightweight stuff bag
DOWNTEK WATER REPELLENT DOWN
DownTek-treated down absorbs less water than untreated down. This means it retains its loft better in damp or humid conditions, dries quicker, and recovers better too, keeping you warmer in damp environments than untreated down.
DownTek is environmentally safe - Bluesign approved, PFC, PFOA, and PFOS free – and uses only RDS certified down sources.
Remember, it's better not to get your down wet – even water repellent down is no substitute for a waterproof shell!
RESPONSIBLE DOWN STANDARD
We use only RDS certified down; all our down is audited by a third party to ensure that it comes from birds who are not live-plucked, force-fed, or mistreated. That’s good to know.

Initial thoughts on PipeDream 400 Hydrophobic Long
Just done a dry run on the bed and this bag seems to be all it promises to be; snug, good fit with plenty of riggle room despite the warning of a tight fit and feels like it will be adequately warm for 3 season UK use. The supplied stuff sac isn't up to much so put mine into a 10 lt sea to summit dry bag with plenty of room; weight 941gms. I'm fair chuffed!
First rate piece of kit.
To be fair I haven't used this product yet, but can't wait as I have just taken delivery of it.
Very quick delivery and secure package.
The feel and workmanship of this sleeping bag is excellent and the provided storage bag and stuff sack are nice touches.
Thanks to the Alpkit team!
great sleeping bag, light warm perfect, saved me on my trip. 10 days in a tent in late September in Iceland and i wasn't cold once. For cost/weight/size i think its one of the best on the market. and British! cant recommend more. I work as a rep and hear great things about Alpkit products in general from everyone i meet. also very good customer service, very helpful people so thank you very much
Brilliant sleeping partner
From bikepacking to wild camping to sleeping on a friends sofa, this is a quality sleeping bag and worth every penny.
terrific light weight bag - fab for bike packing
Bought this for winter use with a cloud cover, and for those colder months around summer. So far haven't needed the cloud cover. Camped in subzero temperatures on the Yorkshire three Peaks and was so warm it was unzipped all night. Then on the summit of Snowdon where it was -6˚ and blowing a gale. This time zipped it up but was still warm and comfortable.
It's lightweight, roomy, packs down well in a stuff sack, is warm and really well priced. Recommended.
Spring trip to NZ South island
I used this bag through November 2016 in the S.Island NZ for backcountry fishing exploits - down to around 0 degrees some nights. This bag is made for such a climate and as an all round solution for world travellers avoiding Alpine conditions below around -5 min it must be one of the very best out there. Very comfortable dimensions for me 5'11" 98kg broad shouldered and superb pack size / weight. No frills so long term test will need appraisal a few years down the line. If it's anything like my old skye-high for durability it will pass with flying colours - would love one in Dark grey, Olive or Black. Alpkit colours a little bright for me generally. Also watch the price as usual guys.
Well made but not the warmest
This bag is certainly very well made and light. Having said that I wish I'd gone for the 600 as I found this bag pretty cold in the Balkans in Spring and the Lake District in Autumn. I definitely wouldn't want to be camping in -6!
really not the warmest
hi! I have used the old PD400 in France,in summer it's good outdoor under the stars,or the rain with Goretex bivy and a 1/2 mat.
But in autumn it's not with 1or 2°C, I was freezing even with underwear in wool,inner bag and the bag all close, the hook and all. this bag is just for mid and warm seasons but absolutely not for under 0°C
for that I've just bought a Carinthia Defence4 at really good price 50% off.
Alpkit is not really serious for rating right confort temperature.
2stars for the lightweight an really tiny place it takes in the Backpack.
The sleeping bag is light and compact but I am constantly cold in this bag, even indoors and with temperatures several degrees above zero. The down seems to move easily when moving or sleeping on the side which creates cold spots.
There is only a small neck baffle on the top (it does not cover all around your neck) and there is no string to tighten around your neck. This becomes an issue when it's too warm to sleep with the bag closed around your face, yet too cold without as a lot of warm air will go out at the neck area.
I bought the bag for temperatures down to 0°C, and with the rating given on the site I thought it should be more than enough. The first night I was cold and after that I looked for the fault in clothing, mat etc. and experimented until I was left to see it is the bag that is cold. I contacted Alpkit with a wish to return it but was neglected and offered a terrible deal. I have had many (many!) cold nights since then as I am a long term traveler and this is the bag I have had to rely on. It has been fine for cold late summer nights or so, but not much more than that. I feel I was completely fooled by the temperature rating and would have spent the extra money for a warmer bag if I knew what to expect in the first place.
Comparing bags from other brands with same amount of down with the same fill power or more you will likely see a higher temperature rating, which leaves me to question the sincerity of Alpkit's given rating.
