    Love my Corus -6c long for 3 years even in shoulder Seasons

    a year ago
    I have had the Corus -6c long for several years. It has become my 3 season sleeping solution. I use it with the neo air pad (R4). I have slept with it in the OR bivvy below 0c/32f in October and my lightweight tent in summer. I have never been cold and I love the weight and the freedom of the quilt when warmer. I would buy again or recommend it. I am 6'2" and 225lbs and I sleep warm. I am planning to use it inside another sleeping bag for winter to get down to -30c. I am looking for the vela -6c double to add to its winter warmth as an adder.

    Great quilt, lightweight, warm (slept two nights at 20-25 degrees), and comfy. Highly recommend.

    Better than a bag

    4 years ago
    We've been (family) using these quilts now for years and choose then consistently over sleeping bags in almost every situation. Yes - they are more drafty than a bag, but the footbox fits well over the end of a pad to keep it steady and the benefits in comfort and freedom of movement are massive = esp. on warmer summer nights. We use them regularly in the mid 30's and above, but pair it with a warmer pad r-value when we know it will be cold. (xtherm or TrailPro) or the older NeoAir All Season). If there's any question, we even bring an extra that can be used over top of two people sideways, or even an extra one per person. In addition to summer backpacking, we also use them religiously on road trips year-round, around the fire, and even sitting on the porch at home. Highly recommend.

    A very simple, versatile, warm down blanket. For ASFOD’s like me (Anglo-Saxon-fat-old-dude) a down blanket offers plenty of room for tossing and turning in the night, and easy to get up in the middle of the night to pee- a definitive character trait of ASFOD’s. Cascade Design excels once again in great product design for outdoor wilderness travel- the only way to go.

    I have used this quilt for many summer and fall adventures. I like that I can sleep in different positions like a blanket, but keeps me warm like a sleeping bag. I have only used in in mild (lows in the 40s) temperatures so I can't state how well it works in really cold temps.

    Great setup live in Colorado have done a few backpack trips digging the light weight and small pack size and not fighting zippers.

    Disappointed

    Lots of cold spots with no down. This quilt is now out of the bag. I spent over an hour redistributing the down, trying to puff it up, there is still multiple large area with no down. I’m actually quite worry now to take that on a trip. It needs more down or a better distribution system.

    I couldn't wait to try this quilt...

    Bought this quilt for 2 reasons, save weight and mummy bags are too restrictive. It is comfortable and lightweight but it provides no insulation from the cold. I used it for 5 nights, all nights were mid-30's, no freezing temps. Had to wake up and redistribute the fill 3-4 times per night and put on multiple extra layers, on top of the base layer, hat, socks, and gloves I was already wearing. Here is the problem, which should have been obvious before I even tried this out, the baffles are all horizontal. When you lay under it the down all falls off to the sides, you end up with no insulation on top of you. Tossing and turning speeds up this process. I loved to idea of this quilt, but I think I will have to look elsewhere.
