Just Brilliant
I got this a few days ago as I want to start backpacking in the summer. The material is silky and soft and the zips move really easily. I usually sleep in the home with two weighted blankets and two duvets on top and last night it was -1 outside. I didn't have the heating on. I used it open as a blanket with nothing on my legs and slept so well I slept through my alarm! As a seeping bag, as soon as you zip it up you can feel the warmth. It's so lightweight. I'm considering buying the envelope one too so I can sleep in this one then layer them up when camping outside if need be as they are so light to carry.

Good warm weather bag
Having been in the army for 23yrs and having slept in many many dossbags for great lengths of time im fully aware you do not need to spend a lot to get a decent sleeping system and I've had one I had in the army for a looong time but just like the quilt on your bed, they lose the thermal retention over time and both my warm weather (called in army not summer bag) and cold weather are past their best im 6ft 3in 21st and this bag fits ok no issues I've got liners so don't see any issues with longevity but don't think ill be still using in 20yrs like my old army one as ill be nearly 80

The stuff sack lets it down
This is a review for the Trinordic summer/light-weight sleeping bag. Overall, this is a very nice lightweight sleeping bag with a green outer and grey inner lining. It has a zip down the right hand side with pulls on both the inside and the outside. However, the zip only extends down the side and not across the bottom so you cannot fully open out the sleeping bag to use as a quilt or blanket. The quality of the bag itself is good, with no significant stitching defects. The recommended temperatures (16 - 19 degrees C) are clearly marked on the inside of the bag, though the outside of the stuff sack says 17 degrees C + so there is a bit of a discrepancy there. I think the footbox is quite small and it feels a bit restrictive to me. For me, the stuff sack is the biggest let-down. The one that I received has a frayed edge which makes me concerned about its longevity. I also found it much harder than is typical to stuff the sleeping bag back into the stuff sack. With most sleeping bags, this can be achieved easily in less than 30 seconds, but this one felt like a battle and took me around 3 - 4 minutes to actually get it back inside. Of particular concern was that there isn't much of a lip to hold onto the stuff sack, and you have to really ram the sleeping bag in quite hard to stop it from just spilling out again. This feels like a recipe for the stuff sack to tear. Finally, the listing pictures make the packed away sleeping bag look much smaller than it really is. The picture of the man holding the bag between his two hands is particularly misleading. It's certainly not as bulky as a winter-weight sleeping bag, but it's chunkier than the pictures suggest. I realise that I've listed a lot of negative points here, but I actually do like the sleeping bag itself other than the small footbox.

Packs down small
Easy to pack down small and warm enough for a summer night

Not for UK camping. Freezing cold at 15°C.
At 15°C in mid-summer France, I had to wear socks, trousers and jumper to keep warm. This provides the same warmth as two bed sheets on top of each other. It consists of two thin slippery synthetic layers with a very thin layer of insulation in between. This would be potentially 'okay' for a Spanish or Italian summer of camping. But not the UK or Northern France.

Really light weight
Used it over night. In the storm we have. December 2024. Just me, the dog and a bivi bag and a ground Matt. Didn’t bother with a poncho over the top as the wind would have just taken it away. Had my Helikon poncho liner on and just this sleeping bag. Over night temperature was about 2c and in the morning about 3c. I’ll keep this one. Plus! The zip didn’t snag once. Stuff sack is good, just wish it was about two inches longer as that would be easier to pack. Still, it went in and we had our walk back to the car and back home for breakfast. I’d recommend it. It is a summer night sleeping bag. Yet, with my poncho liner on it was perfect. Stayed in that nice comfortable heat not too hot and not too cold. To the people who make it. Good on you with the zip. And at 6ft 3 tall, the bag was great.

Great sleeping bag, used weekly for a long time now and still functioning well. Keeps me nice and warm, and packs up small for travel.

Compacto, ligero, buena cremallera
Muy buen saco, es compacto y ligero. No ocupa mucho sitio. Es bastante fácil de guardar en la bolsa. Un punto fuerte: la cremallera parece muy bien hecha para evitar atascarse. Solo lo usaron durante 1 semana de momento pero tiene pinta de aguantar muy bien. Ya lo lavé en lavadora a 40C (y centrifugado bajo) y quedo perfecto.

Sac de couchage très compact commandé pour un road trip moto. Pratique à ranger, doux, de grande taille, confortable et assez chaud à mon goût, j'ai passé d'excellentes nuits !

Good
I love this sleeping bag. It is good and strong material. Also I feel warm. Is not hard or itching if you feel inside. I would say is really comfortable. The only bad thing is that folding it back again is kind of hard. And also since it arrived is not as compact as other sleeping bags. Is not that heavy but is not that compact to in a normal backpack, would take almost all the space inside. Still is really good product and even is not as compact, I still strongly recommend it.
