Sea to Summit Trailhead Thii 30°F/-1°C Long Sleeping Bag

[This review was collected as part of a promotion.] As far a synthetic sleeping bags go, this one seems good for the price! We constructed & designed. On first use, I do not expect that this sleeping bag will actually perform well at its comfort rating, so if you're considering doing some serious winter camping, I would opt for a down sleeping bag maybe.

I’ve used this bag three time and been cold every time. I’m an experienced backpacker with 20 years of experience in a lot of different bags. This does not preformed as advertised. I have the 20 degree bag and was cold at 45 degrees last weekend. I expected it to be less warm than my zero degree bag but not like this. It should be advertised as a summer bag only.

I've had many sleeping bags in 50 years of Scouting and this one was fabulous. It was light, compressable and very warm. Zipper was flawless. I paired it with a Reactor liner to provide comfort to even lower temperatures.

I'm not a hardcore backpack adventurer or anything, but I do love motorcycle camping, so I was looking for a low pack-volume sleeping bag that wasn't outrageously expensive. I'm also 6'1", 210 lbs. so I needed something roomy enough for me to be comfortable. This bag is super comfortable. It's soft and warm and packs down nice and small for stowing in my bike's luggage. I don't know why the reviewer Adam from Germany said it was impossible to get it back into the stuff sack, because I find it to be quite easy to get it back into the sack. It literally takes me about 60 seconds to roll the bag up and stuff it in the sack. I will say that if the temps drop into the 40s or lower, you're going to need a bit more than this bag can offer, so I'm going to get the liner to add that 10-15 degrees in case it gets a little chillier when I'm camping. But down into the 50s (Fahrenheit), with socks and sweats, I was toasty and slept great.

I bought this bag to replace my 20 year old bag which was rated at 20 degrees and served me well. The trailhead is significantly lighter, quality made, the zipper setup allows for good ventilation and packs well.

Only slept in it a few times, but this bag is awesome. Cool to the touch fabric on the inside, easy pull zippers with snags Only with overly quick or harsh use. Compresses and expands with ease.

Warm as rated, decent zippers. Roomy enough to be comfortable, but without carrying extra weight. HOWEVER, the bag simply cannot be put back into its sack UNDER ANY CIRCUMSTANCES, making the packed volume specification a total lie. Even machine packed by the factory this thing is really difficult to get out of the sack, and it's truly impossible to get back in. The headache this brings packing it back up every night is simply not worth it, so I returned it to the store and will buy a bag whose designers put a bit more thought into the user experience. Massive PITA to save what, 2g of extra sack weight for a sack that fits?

This is a bulky bag. I would reserve it for car camping/base camping. It’s too much to Cary. For the price there might be better options but it is certainly a very well made bag.
