The Ascent 300 is a versatile, summer bag with a comfortable, wide mummy fit. Filled with 300g of 650FP goose down and with space for wearing additional layers if needed, this bag is perfect for summer climbing trips or bothy-based adventures in mild conditions.
The Ascent is built with a lightweight and durable, recycled Pertex Quantum outer fabric and recycled nylon lining. It has trapezoid shaped, boxwall baffles that stack neatly together, encouraging the hydrophobic duck down inside to loft fully and reducing the appearance of cold spots. Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, maintaining the down's loft and warmth.
The generous mummy fit with wide foot box provide a spacious feel for an easy night's sleep, and the close-fitting neck baffle keeps the heat in when the temperature drops. It has a ¾ length main zip with a down filled baffle to keep out the draught.
Practicalities are taken care of with an internal zipped stash pocket that easily fits a phone or a headlamp, a cotton storage sack and a compression stuff sack to ensure a manageable pack size and protection on the road. Exploring with a partner or want extra space? Pick up a left and a right zipped bag and you can zip them together.

Great duvet insert at a budget price
Size: Queen, Color: White
I'm new to using a duvet so I had no idea where to even start when it came to a duvet insert. I decided on this one and what a great decision that was. This duvet insert is perfect and fit my queen size cover perfectly. It did arrive vacuum sealed but once you cut it open it quickly regained its shape. I did throw it in the dryer for 10mins with no heat and that seemed to help add an extra layer of fluffiness but I do not think that is necessary for everyone. This duvet insert is perfect for all year around because it is not heavy, so it will keep you warm without getting too hot in the summer. Overall, I am very pleased with my purchase and I would highly recommend. Also, it is washable which is such a plus!

Great buy
Size: Twin, Color: White
Pros:
1) Has held up well in the washer/dryer
2) lowest price I could find for down alternative comforters without a high return rate
3) My fur kids adore this brand vs similar big box store brands, especially my finicky cats.
4) Very soft
Cons:
None that I have experienced.
I started searching and found Utopia after Target decided to raise the price on their down alternative comforters.
This comforter is a light weight style that holds its own on laundry day, and isn't too heavy in our warm climate. It is great for a multi species household. Team Double Trouble loves it on their raised dog bed (amazon brand), Team Murder Mittens love it on their kitty city condos (available here on amazon) to sunbathe or bird watch, and I like it too as a hot sleeper. It really is a perfect all purpose comforter. 10/10 would buy again.

Pleasant surprise, warm and fluffy
Size: Queen, Color: White, Size: Queen, Color: White
For the past couple years my girlfriend and I have gone through a few cheap comforters. We never really gave much thought to them and subsequently they never impressed us. I grew up using a down comforter and have very fond memories of that blanket. The comfort and warmth was something that I hadn't experienced since I had moved out and gotten my own comforter. So this has been in the back of my mind ever since but I wasn't sure if I wanted to dish out that kind of money for a blanket and also deal with the hassle of dry cleaning it. Also by purchasing a down blanket we'd be supporting an industry in which the down feathers from geese are taken from them and that's not something we personally wanted to support. So for all those reason we started looking into down alternative. The first thing that made me question these products was the price, they seem TOO cheap. I was raised with the mantra, "you get what you pay for" and with that in mind I was quite weary when looking at these products. I always make sure to compare many different products and read through the reviews, both good and bad before I buy something. I decided to take a chance on this particular one as it seemed to be the highest rated by customers and I liked what I saw in the images provided by said customer. If anything, the price was low enough that I wasn't too worried if I didn't end up liking it.
Now I wasn't actually home when it arrived but my girlfriend confirmed that it was very flat right out of the package, as was expected. By the time I got home 2-3 hours later it appeared to be fully fluffed. The material it is made of is very soft and comfortable on your skin and I was pleasantly surprised with the thickness/fluffyness. It is a fairly light blanket, similar to a down blanket I suppose in that regard. So far I have only slept with it one night but it did a great job of keeping me warm. I live in Wisconsin and the temperatures this week have been ranging from -10 over night to single digits during the day. I had been using 2 blankets prior to getting this one and sometimes I would still wake up in the night feeling cold. But so far with this blanket alone I have stayed warm which again was a pleasant surprise.
I do have to say that this doesn't remind me a whole lot of my down blanket and I think that may have to do with the material used in the shell. And you're not going to be 100% able to recreate a down blanket not using down. So if you are looking for something that feels exactly like down and won't be satisfied otherwise, this might not be for you. However, if you are looking for a good quality, warm, fluffy and affordable priced blanket that will give you that "cloud" like feeling, I think you would be really happy with this blanket.
Again this is my opinion from using it for one night, I can not comment on the durability or longevity of this blanket, but I am hoping that it holds up over time.
**also our cats immediately fell in love with it, it is their new favorite spot to nap.

High quality duvet!
Size: Twin XL, Color: White, Size: Twin XL, Color: White
Extremely comfortable, soft, and thick duvet! It is also very light despite its thickness, and it makes all my comforters look super fluffy. It keeps me warm without making me sweat. It’s easy to wash, high quality, and it has 3 loops on all 4 sides of the comforter. You could also use this duvet by itself if you wanted to since it is so comfortable and looks like a white comforter on its own. Absolutely love this duvet and do recommend!
(I will add another photo of the duvet by itself when I take the duvet cover off to wash it)
