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.

You can have as many sleeping bags as you want – down and synthetic, summer and winter weights – but there’ll always be one bag you immediately reach for to cover all eventualities.

The PipeDream 400 is a lightweight, compressible bag with an excellent warmth to weight ratio. We’ve used 400 grams of 750 fill power down to provide lots of lofty warmth without compromising on weight. With no unnecessary features, weighing a mere 865 g and packing down as small as 19x14 cm (smaller than your average melon), it’s the ideal bag for multiday backpacking, bikepacking and cycle touring. There are lots of variables (including how much you’ve had to eat before bed - eating a full wheel of camembert usually does the trick!), but, for us, the PipeDream 400 is the ideal level of down fill for 3-season use in the UK, summer alpine climbing, or even as a liner bag for winter use.  

Horizontal box-wall baffles eradicate cold spots and prevent down migration and a tapered mummy shape ensures the bag is as thermally efficient as possible by reducing the amount of internal air. The drawcord hood closure, neck baffle and full-length zip baffle keep out draughts, trapping precious warm air when the temperature drops. 

The PipeDream 400 has a water-resistant PFC-free DWR coating, so the odd drip of condensation or early morning dew won't ruin your bag’s insulation. DownTek™ Hydrophobic down also loses less of its warmth when wet, dries quicker and recovers better from moisture. We’d still recommend packing your PipeDream in a waterproof Airlok when you’re going nice places and doing good things though for extra piece of mind. Supplied with a cotton lofting bag for storage and a lightweight compression bag.

Environmental Considerations

DOWNTEK PFC-FREE 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.

Warm and toasty

I have had this bag for some time now and it’s brilliant. Packs down exceptionally small (great for bike packing) and is very light. Yet it’s super warm. Can’t recommend this enough if you want small, light but warm.
