The Sea to Summit Women’sTrek TkII is designed for those who like the versatility of a tapered bag, but don’t want to feel constricted while they sleep.
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.
The length of this bag is reduced for a closer fit, and the hip area is widened for added roominess for a women’s specific fit. This bag also comes with two combined down and Thermolite synthetic baffles under the foot area which will keep your heels and ankles warm in the area where feet can compress the down.
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 TkII is the sleeping bag for the traveller or hiker wanting a bag that will get them through most non-extreme conditions.
Loving this sleeping bag. I have found it super toasty and very roomy for its weight. Perfect for winter hiking
Purchased this model after comparing several sea to summit sleeping bags, and this one seemed to fit my requirements (being a cold sleeper, the comfort rating of -8 degrees appealed to me) and as I would be using it for trekking, the weight also appeared to be manageable. However having used it several times indoors, I have found it surprisingly not warm enough for my needs, and it is also very bulky in it's compression bag. It also has a strange scent (from the duck down?).
I'm sorry to hear that you're having trouble getting in a cozy nights sleep with your new sleeping bag.
This comes as a bit of a surprise as we've only ever received positive feedback about the Sea to Summit sleeping bags - but every sleeper is different. Which is why we put together a blog post on Toasty Tips to Make your Sleeping Bag Warmer.
Also, the bedding you decide on plays a big part - for example, for maximum warmth - avoid an airbed, stick to insulated mats. I hope this helps and that you can now have a toasty warm sleep. Laine :)
Hi, I am looking for a Right hand Zip Bag to go combine with the regular wide version of men's trek II sleeping bag. Which bag do you guys recommend? The height on this one seems to be a little shorter than the men's regular. Thanks
You're right, it is a little shorter. That's one of the key differences between the men's and women's sleeping bags. The best thing to do when trying to zip sleeping bags together is to use the same model of sleeping bag. This ensures the zips are compatible, they align in sizing and there is consistency in temperature ratings. It does also become a little harder with the down insulated bags because of their mummy styled shape.
Hi, just wanted to know the difference in trekking versus hiking in your 'suggested use' section, I would have thought they were the same thing, yet this bag is suggested for trekking but not hiking, and other series are ticking both boxes. I'm thinking of purchasing this bag to do the overland track in Tassie this December.
This is an oversight on our end and should say Hiking and Trekking which we'll update. Basically, as you mentioned there isn't much of a difference. We refer to trekking as multi-day trips (like the Overland Track) where weight and quality are critical and Hiking as a few days away (like 2x nights in your local National Park) where weight and quality may not be as much of a concern. All trekking bags can obviously be used for hiking.
The Sea to Summit Trek WTkII Women's Sleeping Bag would fit into both the Trekking and Hiking usage categories.
Hello Snowys, in a couple of weeks I'm spending 2 weeks camping in Western Canada. As we're spending time in the Mountains, and I really feel the cold (I'm from Queensland), I'm looking for a warm sleeping bag. I'm only 152cm tall, so don't need a huge bag. Is the WTkII what you would suggest? Many thanks
Great question. In comparing the Sea to Summit Basecamp Bt4 (from your other question) and the Sea to Summit Trek WTkII Women's, my recommendation would definitely be the Trek sleeping bag. This is because this bag is filled with 650 Loft Ultra Dry™ Premium Duck Down compared to the Synthetic fill in the Bt4. This reduces the weight of the bag (by 1kg) and will provide much better and comfy insulation against the cold. The other benefit is that the Trek is a 'mummy' shaped bag ensuring that you'll be wrapped up to keep you warm.
Another consideration if you're really concerned about the cold is the Sea to Summit Latitude WTkII Women's which can be found here. This bag adds a further 2C of warmth on top of the Trek bag.
Alternatively, you can look at the Sea to Summit Thermolite Liners (we'd recommend a liner of some kind to protect the bag anyway). The Thermolite Liners have insulating properties with the warmest option offering an additional 15C which can be found here.
I'm 171cm but the bag description says max user height 170cm, is there a bit of give in that specification? Or is it if the bag hood was pulled in & legs were stretched out it may be tight?
The maximum user height incorporates all the height space available and is measured from the end of the foot well all the way through to the top of the hood. This is because the temperature rating incorporates the value of the hood is preventing warmth from escaping the body through your head. Unfortunately, at the moment, Sea to Summit have only released the one size for their new women's bags.
