Are you a bit … broader in the shoulder? Or, like George Costanza, don’t like to be too constricted when you sleep. “I like to be able to take the blankets and swish them and swirl them.” The Sea to Summit Trek Tk1 is the sleeping bag for the traveller that likes a bit of room to move.
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 5.1L. The Trek Tk1 is a bag designed for the world traveller. In its element in a hostel bunk, but light enough for warm weather trekking.

How accurate are temperature rating System?1 answer
I have a Trek Tk1 .and will be trekking in Iceland in August. Some time spent in huts and some in tents. We have been advised to bring a sleeping bag rated +10 to -10. Do you think the Trek Tk 1 will meet my needs ?
Tanya - Eight Mile Plains(8 years ago)
I wish there was a simple answer to this one Tanya. These bags are tested to an international standard, the EN13537 standard, which has a dummy lying in a motionless position with sensors monitoring temperature in a controlled environment. In the real world you move around, the temperature changes and there are factors like wind, the mat you're sleeping on, what you're wearing, your metabolism and what you ate for dinner to take into consideration to mention a few. You won't find a bag rated from +10° to -10°, this is a huge range and most bags will have a rating within an 5° to 8° range. The comfort ratings on the bags are generally allow for an average female to sleep comfortably in a relaxed position, and for cold sleepers this should be considered the limit for the bag. Long story short, I don't think the TK1 will be warm enough for your trip. You could get away with it but you'll need a thermal liner and a well insulated mat to sleep on along with some good thermals, socks and gloves. A sleeping bag with at least a -8° to -10° comfort rating would be more suitable choice for these cold environments.

Can two of these bags be zipped together? 1 answer
Emma - CHRISTIES BEACH, SA(9 years ago)
You can join two of these bags together Emma, provided you have opposite sided zippers. There are two zips, one down the side and one along the bottom. The side zips are used to join the bags together.
