The warmest bag in the Sea to Summit Trek range of sleeping bags, the Tk3 is a bag for those with a wider frame not wanting to resort to a more restrictive mummy shaped bag. Packing down to 5L, it’ll fit neatly in the bottom of most trekking packs.
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 slickers for space. The full length side and foot zips mean you can zip it wide open and use it as a quilt, for those warm nights or if you have company. A two-dimensional hood is useful for trapping extra warmth on those colder nights.
An oversize internal pocket is big enough to keep your wallet, passport, and iGadget. The lightweight Ultra-Sil® compression bag compresses the bag down to a mere 7L. The Trek Tk1 is a bag for the trekker wanting a freer night sleep, but with the warmth to get them through a cold night in the hut.
Prompt service, fast delivery.
Great bag ( I am 183cm) very warm and comfortable.
So happy I spent a little extra and purchased the warmer tklll, Even when the temp reached around 7 degrees Celsius I simply opened up the bottom and it was comfortable. The width/length is great for my wide build 6'2 body. Packs easily away into a small size.
Purchase and delivery was excellent. We bought two of these sleeping bags. First night of using them it was at 1300 metres in Victorian High Country, A cold wet stormy night and we were warm and slept well. Highly recommend the product.
This sleeping bag has very high quality in every area. Nothing to complain. It's just perfect for me in winter. The price at Snowy is the best I found in Aust. The delivery was faster than I expected. It's like someone done the shopping for you and delivered to your door in a flash. I am fully satisfied. It's excellent experience to shop at Snowys.
Is the sleeping bag Trek III still comfortable to be used in the summer at 15 ° C
The Seat to Summit Trek TkIII is the warmest in their Trek range and it has a comfort rating of -5 degrees so it is designed for Autumn/Winter weather.
I would say that if you’re cold at home on a 15° night, then chances are you’d want a bag that was on the warmer side like the TkIII. If you’re a hot sleeper you might want to consider the TkII as that has a -1 ° rating.
As far as we know there aren’t any bags that are designed to be used in Summer and Winter, but in general it’s better to be a little too warm and unzip your bag, then be too cold and not be able to do anything about it when you’re out in the elements.
This range talks about being suited for larger framed men but im wondering whether it would be suitable for someone smaller such as myself? I like the idea of a little more room but would too much heat be wasted? Id be using it in places where the temperature would never drop below -5°C. Thanks.
Under details it states the comfort rating is -1. Is it -1 or -11?
I'm deciding between the Trek 2 and 3. Trek 3 is about 200g more than Trek 2. Would that make much of a difference when hiking in terms of space and weight overall? Also, I'd like to use it for camping out in country and/or alpine areas during June and July, would the Trek 2 still be sufficient for the colder nights or will the Trek 3 be a better option if temperatures are freezing or below?
