Description

A hoodless sleeping bag of amazingly low weight and bulk, which opens up new possibilities. Suitable as essential kit on a planned extreme ascent through to confidence-boosting backup in any mountain country:

  • Multi-day ascent in Patagonia or Alaska? Customise the Delta 550 with a full water-resistant Ultrashell inner, and with a width extender to turn your bag into a double
  • Alpine-style ascent in the Himalayas? The Delta 550 can take you high, twinned with the right clothing

The water-resistant Ultrashell outer protects from condensation, and Ultrashell panels inside protect from damp. The reflective strip for night location and the clip loop to organise on a belay ledge are part of a superb features list.

The optional zip-in Width Extender turns your single bag into a double.

Sleeping Bag Width Extender

PHD's fully insulated width extender converts a single Delta sleeping bag into a bag for two. It's attached to the bag by its full length zip and is fully insulated by the host bag's own draft tubes. The insulation level matches that of the host bag to insure consistent warmth. An extender requires a full length zip to be chosen and can only be ordered at the same time as the bag.

Ultrashell (weight: 40gsm)

The lightest of PHD's coated materials. This ripstop nylon provides complete wind block and good water resistance at minimal weight. Ultrashell gives an excellent upgrade to performance with very little weight penalty. Order samples of this fabric & just pay the postage.

Superlight MX fabric (weight: 32 gsm)

A mini-ripstop nylon with excellent tear strength, MX is the pick of the superfine 15 denier downproof materials. We have tested lighter fabrics, but most have had significant drawbacks, while our confidence in MX is based on several years of extensive use in both our ultralight and our high mountain gear. Order samples of this fabric & just pay the postage.

Sleeping Bag Zips

  • No zip: The standard design on our lightest bags with open hoods. The simplest/lightest system which is a must for adventure racers. Up to 140gm (5oz) lighter than a full zip with draft tube.
  • Full zips: Full zip bags ventilate well, so they can be used over a wider range of temperatures.
  • Short Zips: Short zips are lighter and pack smaller than full zips. A short zip & draft tube is about 85gm (3oz) lighter than the full version.
  • Our full briefing on sleeping bag zips.

900 Fillpower Down

European goose down of very high quality. A truly excellent down with large clusters, consistent quality and lively long-term performance. More on our down insulation.

Construction

This bag has an insulating straight wall baffle system throughout (no straight-through stitching). Straight wall is the lightest of all baffle sytems. In cross section it looks like this:

More on sleeping bag construction.

Proofed Inner Panels

Proofed fabric (Drishell or Ultrashell) panels are included inside the hood and foot areas of the bag to help keep the down dry. In very cold temperatures your breath can cause ice to form around the face opening, which may soak into the down as it melts. The panels at the foot end are to protect the down if you get into your bag with wet socks (or in extreme situations with your boots on).
