G'day Heather, 

The Traveller is realistically one of the only ones that will suit the requirements you've mentioned.
It might be worth mentioning that we recommend choosing a bag with a comfort temperature around 5 degrees lower than expected temperatures to offset any variables that may effect how warm you sleep.
Based on that, a 5C bag would be recommended for real life temperatures 10C and above.

The Traveller also opens up completely like a quilt so if you're wanting abit more space to move around, that would be a good way to do it.  The difference between the regular and the large is primarily the length, so we'd recommend choose the one with a user heigh best suited to you.

Give us a buzz on 1300 914 007 if you've got any more questions or you'd like to talk through some other options.

G'day Bill,

The Traveller is a tapered shape bag, so either the taper or rectangular mat would be fine to use.
If you are a side sleeper and you toss about in your sleep abit, the rectangular mat would be a good option (if you dont mind the extra pack size/weight) as it gives you more space to move about.

G'day Belinda,

The Traveller series is only made with a left zipper.  To join them together the bags open out flat and zip around the edge like a sandwich.

G'day Steve,

I've just weight the Traveller Tr2 Regular for you and I can confirmed that 645g is the weight of the bag without the compression sack. The compression sack is 60g, so your total carrying weight will be 705g.

G'day Ted,

Yes the dimensions are correct for the Tr2 - Long. When you select the Long in the drop-down menu the specifications will update and reflect the greater length and width. You should be able to zip the bag to your other Tr1, as they are compatible with other Traveller modes. 

G'day Pete,

The Traveller Tr2 doesn't have a foot zip, it instead has a drawcord to cinch in and keep your feet warm by trapping your body heat 

G'day Yvette,

I've just double-checked the Sea to Summit catalogue and can confirm the details are correct for the Traveller Tr2. The Tr2 comfort rating is 5'C and the Lower limit is -1'C.

G'day Deana,

Great question! These are actually the Tr1 weight specs, so thanks so much for picking that up!  The correct weight for the Sea to Summit Tr2 - Regular is 645g.

G'day Michael,

I've just double checked the specifications on the new model Sea to Summit Travellers and yes you can zip a TR1 & TR2 together to make a double.

G'day Luke,

Comparing the Traveller (Tr1 or Tr2) with the Pilbara is a tricky one mate as they are completely different sleeping bags compromising very different materials.  Obviously, your Pilbara is cotton, whereas Sea to Summit uses Ultra-Dry Down to fill their Traveller with a Nylon outer.  The Tr1 packs down to a neat 18cm x 10.5cm, making it the most space efficient of the Travellers and with its comfort rating of 14'C stands out to me as being a pretty good choice for taking to Byron.  However, I understand your concerns over it offering enough warmth for Tassie hiking conditions!  You could still go with it and consider using an insulated mat for future adventures which make a considerable difference to that ground chill factor for overnight hikes.  In addition, there's the option of using a thermal liner for extra warmth if suddenly that Tassie summer night dropped in temp?  These options would offer more versatility so you could use your gear in varying climates but for your immediate needs, my recommendation would be the Tr1.  Hope that helps mate and have a great time at Bluesfest :)
