Sea to Summit Trek Series Sleeping Bag Watch video

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.

Quality down lightweight and warm

Excellent sleeping bag. I bought it for lightweight and compact backpacking. Haven't tested it below 5 degrees yet, but it feels like it will be comfortable and cosy. I like the extra room and the zips are good, no snags. Snowys are a great on line service delivery company.

Good size, weight and value 2/3 season bag

Just completed the South Coast Track in Tasmania in February and used a TK1 for myself and a TK2 for my wife. Used for 10 days in a tent with silk liners with night temps 5 - 10 degrees. Very happy with the leg room, warmth, as well as the compact size and weight saving. Also like the included compression sack, and zippered home loose storage sack.

Warmth to weight is great

Love how it opens right up to create a blanket. Highly recommended. Haven't tested against my other bags, however a friend thought it was warmer than another, rated 5 degrees colder. I think that was because this could open right up. Compresses well. Fast delivery. Thumbs up!

Not value for money

My first trip out with my daughter (seasoned hiker), hiked the Warrumbungles over long weekend, temperatures went down to 5 deg C, with fleece hoody on with thermals underneath and jeans and thick socks on I froze in this bag while my daughter in her $59 -5 was very comfortable. Very disappointed in performance, bag does seem to be well made and ultralight but at the end of the day comfort is what its all about and this bag does not deliver. Slept in new Isopod tent.

Response from Snowys Jun 17 2016

G'day Rob, I'm really sorry to hear that you had a rubbish nights sleep. Sleeping bag ratings are a bit tricky, it really depends on what type of sleeper you are. For someone who feels the cold quicker than others, I'd strongly suggest an insulated sleeping mat. This will reduce the amount of body-heat escaping through the ground. We're confident in the performance of these sleeping bags, so please give us a call, we would like to help you sleep warm on your next trip. Laine

Great bag - funny smell

This bag is really warm for its weight. Really comfortable and packs down incredibly small. The only thing I don't like is the smell. Really hard to describe - I guess its a chemical smell.

Impressive

Super lightweight and compresses down to the size of a drink bottle. Great for multi-day adventures when counting the grams. Not constricting like a mummy bag and was even able to fit Thermarest mattress inside the bag! On one night, temp dropped to just below zero inside the tent, yet with some thermals on, was more than comfortable inside the bag. Big thumbs up!

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 ?

- Eight Mile Plains(1 year 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

- CHRISTIES BEACH, SA(2 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.
