The Sea to Summit Trek TkII is designed for those who like the versatility of a tapered bag, but don’t want to feel constricted while they sleep. At just over 1kg and packing down to 6L and with -1â°C in warmth, the TkII is the ultimate all-rounder.
The bag incorporates highly breathable 2D PermaShell™ fabric which will keep your down in tip-top shape. The tapered rectangle design makes the Trek ideal for people with a larger frame or who prefer a roomy bag. The full-length side and foot zips mean you can zip it wide open and use it as a quilt for balmier nights, or have your feet poking out if you need some air flow while you sleep. And, in colder weather, the two-dimensional hood is will help trap warmth for a soundless night’s sleep in the elements.
Featuring an oversize internal pocket that’s big enough to keep your wallet, passport, and gadgets close while you doze. The included lightweight Ultra-Sil® compression bag will compress the bag down to a mere 6L for easy packing. The Trek Tk2 is the sleeping bag for the traveller or hiker wanting a bag that will get them through most non-extreme conditions.
Can the zips line up,
G'day Ruella,
Unfortunately, the Sea to Summit Trek TkII Sleeping Bag isn't designed to have two zipped together.
I notice on your web site the packed size (compression bag) for the regular size is 36x15 while on another suppliers site, what looks to be the same sleeping bag is listed as 26x17 packed size. I’m hoping for a compact bag and wonder, Could there be an error In your listed details? Thanks
G'day Liz,
Sorry for any confusion we've created with our packed measurements on the Sea to Summit Trek TkII. The packed dimensions we show are how they come to us from the factory, which isn't in a compressed state. I've just tried to recreate the 26 x 17cm dimensions that you found on another website. If I really compressed the bag as much as I could in the compression bag, then it turned out to be about the 26 x 17cm, I was hoping for. With bags like this, the dimensions always depend on how much you compress them, so you should definitely be able to get it that small.
On Sea to Summit's own Feature Matrix it gives the width of the Trek11 regular as hip 150 and your details has it at 146. Is the orange version a different size?
Howdy Diana,
The orange is the new version of the Trek TkII Sleeping Bag as they recently changed their line. This bag may feature a slightly different girth to the older model with the black on the outside. If you did see this bag as the orange version with 150mm on the Sea to Summit web page I would suggest that figure would be correct.
Hi there, saw that there's 2 versions of S2S Trek sleeping bag. Any difference between the two?
G'day Danny,
I've got the 2017 Sea to Summit Catalogue in front of me right now, and it seems that they've just given the trek range a facelift in terms of colour, and it now comes in a women's and wide fit size.
