By using high warmth-to-weight ratio 750 FP down the PipeDream 600 packs in a helluva-lot of insulating loft for just a shade over a kilogram (1065g). With this comparatively low weight and no unnecessary features, it’s the ideal bag for fast and light sub-zero expeditions.

There are lots of variables (including how much you’ve had to eat before bed - eating an entire packet of Jamaican Ginger Cake usually does the trick) but we think this is the ideal level of fill for 3-4 season use in the UK or summer alpine climbing.

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, 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 mercy drops below freezing.

The PipeDream 600 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.

Care & Environmental Advice

Environmental considerations


As part of our continuing effort to remove long-chain flurocarbons from our products, we’re now introducing C0 Durable Water Repellent (DWR) treatments to our sleeping bags. Despite the slight impact on performance when compared to C6 DWRs, C0 DWRs are non-toxic and completely PFC-free, causing significantly less environmental damage. We fully support this change. In fact, we quite like the idea of taking time to look after our kit so that it lasts a long time. We’re committed to reducing the environmental impact of all our products, reviewing the materials we use, manufacturing methods and our own consumption of resources. We do the research, make informed decisions, and choose the best option available to us. 


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.
