    1. G’Day Scott –

      Thanks for your question. The short answer is, yes, you can zip together a Regular and a Large Traveller.

      The longer answer is that:

      – All Travellers have left-hand zips, so one of the two bags will be turned ‘inside out’ when they are zipped together. This will not affect their function.
      – The zipper of the Large Traveller will be longer than the Regular Traveller, and will project out at the top end of the sleeping bag. Because both bags are tapered rectangular in shape (rather than mummy shaped), this will not be a factor in use: simply lay the bags down so that the zipper is at the side rather than in between the two sleepers.

      Please bear in mind that the zipper used is a very lightweight #3 YKK zipper; care should be taken not to apply too much force laterally across the zipper, especially if it is in a partially-opened state.

      I trust the above is helpful



    1. G’Day, Matt

      Thanks for checking with us on the specifications for the Traveller Tr I

      We measure compressed volumes using the ASTM standard; using this method, the Regular Traveller can be compressed down to 1.55 Liters. In practice, you might be able to squeeze it down to 1.4 Liters (for comparison, the external volume of a 1 Liter Nalgene bottle is around 1.3 Liters).

      The Traveller Tr I is rated for a male sleeper according to the EN standard (EN 13537) at 50*F / 10*C

      If you have additional questions, shoot us an email at – we’ll be happy to help



  1. seems this bag might be a little to cool for early may hiking(Ontario), my question is would one of your bag liners do the trick for getting this bag a little warmer

    1. G’Day Jamie

      Thanks for your question regarding the use of the Traveller Tr I sleeping bag in Ontario.

      The average nighttime air temperature in Ontario in early May is around 5°C / 40°F, with the possibility of freezing temperatures in the early hours before dawn. This is well outside the design parameters of the Traveller sleeping bag, which is rated down to 10°C / 50°F for a male sleeper and 14°C / 57°F for a female sleeper.

      It would be possible to address some of this differential by adding a liner such as the Thermolite® Reactor Extreme or the Thermolite® Reactor Fleece.

      However, we’re reluctant to recommend a Traveller plus a liner as a sleeping system for these conditions due to the following:

      – The Traveller excels as a travel / summer backpacking / hut touring sleeping bag because of its very light weight (Regular: 389g) and very small packed volume. Adding a liner which weighs 400g or 420g largely negates the light weight advantage.
      – As a summer sleeping bag/quilt, the Traveller does not have a hood. We would regard a hood with a drawcord as essential at temperatures around the freezing point.

      A far better option would be the Micro Mc II (bag weight 630g | Lower rating 2°C / 36°F). The Micro has a hood, and also features a full-length zipper and drawcord base similar to the Traveller. It also has a highly water-resistant shell fabric which might be an advantage given the possibility of condensation in Ontario at this time of year.

      I trust the above is helpful – if you have additional questions, drop us an email at and put “Traveller Tr I – follow-up questions” in the subject line.
