1. Select Zip

Most right-handers prefer left zip bags as it's easier to reach across your body to your left side to use the zip when lying on your back. The opposite is true if you are left-handed.

Whether you’re running a Mountain Marathon, embarking on an ultra-light self-supported ride, or heading out for a midweek boulder and bivvy; PipeDream will leave you feeling light and unhampered without sacrificing a good night’s sleep.

Fine-tuned for maximum insulation without the bulk, PipeDream 400 combines high quality 750+ IDFB fill power goose down with a minimalist design to create a simple and ultralight bag.

A comfortably spacious cut gives a natural night’s sleep, with adjustable head closure and a sculpted neck baffle for snuggling down to fend off the draughts. Box-wall baffles minimise weight and prevent down migration; Nikwax Hydrophobic down and a DWR coating ensures that the early morning dew won't ruin your bag’s insulation.

With a tiny packed-size, PipeDream stows away easily and lofts effortlessly when you need it.


Nikwax Hydrophobic is a water repellent treatment that makes down less susceptible to humid conditions, staying lofted for longer and prolonging the overall lifespan of your down.


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 know.

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.

Brilliant bag

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.

terrific bag

terrific light weight bag - fab for bike packing

Brilliant sleeping partner

From bikepacking to wild camping to sleeping on a friends sofa, this is a quality sleeping bag and worth every penny.

Iceland Adventures

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 smile



Active Traveller: Pipedream 400

An excellent value, high specced sleeping bag with water-resistant down a bonus.
