Pipedream 400 Long Hydrophobic lightweight sleeping bag
-4˚C limit 3 season lightweight sleeping bag weighing 910 g with Nikwax Hydrophobic goose down; ideal for moving fast and light or lining your winter bag
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 long 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 DOWN
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.
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.

Quality lightweight autumn bag
I just tested the PD400 long in The Lake District after agonising over this or the PD600 long. I’m 6’4” tall, 15st and couldn’t tell you if I’m a hot or cold sleeper! I wanted the bag for use up to and occasionally just below zero.
On the night I was wearing fleece lined cycling leggings, a thin fleece jumper and socks. The overnight temp was 4 degrees. I was comfortably warm all night and arguably a bit too hot at the beginning. At no point did I wake in the night and feel cold spots.
The bag loses a star for me because I don’t think it would be comfortable down to the ‘comfort’ rating of -4 (but does anyone ever really expect a bag to live up to manufacturer ratings?). It is, however, very light, packable and comfortable. It’s very versatile for me as a light autumn bag which will do sub zero with the addition of a thermal liner.
Pipedream 400 long review
I have found that the sleeping bag feels like it is well made and manufactured. However when in cold conditions it seems to get cold spots in some areas. I'm no expert, but it feels as though it needs more down as it is the long version.
