Alpkit - Pipedream 400

Alpkit down sleeping bag. Best bet for down bags, used mine 3 years and has been perfect

I think the issue with temps may be due to the fact that they don’t put more down in the long length sleeping bags, combined with more people needing long in Alpkit bags than other brand (I do at 6’1”, but fit a standard Rab Ascent fine). In my PD400 the down isn’t very well distributed and has very little where you need it most, loads where it adds little value. To be fair I’ve never really pursued this with them as I’d used it a few times before I noticed. As you say loads of good reviews but I’d give a sleeping bag a good once over if you mail order it from them and all will be well, I think the issue is QC not absolute quality with them. Love my Ascent 500, there’s definitely more bulk with 650fp down than 800 but in a way it’s feels cosier inside and I’m using the same compression stuff sack, it’s just a bit fuller. Dead roomy inside. The fabric inside is a bit nicer on the skin than Alpkits but only at the level of splitting hairs. Decathlon do outstanding value down sleeping bags but the fit is very narrow at the feet and the down isn’t hydrophobic.

A 20 (F) degree bag is generally considered the best all round temperature. The Alpkit pipedream 400 has a 20 rating, weighs just 860g and is a great price. I noticed a lightly used one on eBay earlier too. Hard to beat.

I sleep in a 400 in the same weather as my wife in her 600. It's rare that I'll add extra layers compared to her. Even around the house we run more or less to gender norms of her being constantly cold and me being fine wearing a layer or two less than she has on.

I've got the same bag as you and also use a Mountain Equipment Helium Quilt (https://www.tauntonleisure.com/sleep-equipment-accessories/sleeping-bags/mountain-equipment-helium-quilt__14482) when it's warmer. I've also used both together to add warmth.

Alpkit Pipedream 400 (or 600 for a solid 4 season). And they are on sale right now!

I've never had a problem with my Pipedream 400. Great bag: packs small, great price and does exactly what it says it does.

Temp rating seems about right, though unless you are on laboratory conditions it's hard to tell! (Temperatures inside tents tend to vary with wind, number of people in there, sleeping mat quality etc etc). I've certainly used it sub zero many times, without a liner, and just in a base layer. Quality is good. I've had mine for about 8 years and there's no sign of down loss or movement.

Yeh they seem to be good. I've got the 800 and it's fantastic, been on multiple below zero camps with it and been toasty warm. Obviously heavier than my alpkit pipedream 400 but that thing is nowhere near as warm as it's made out to be, can really tell the difference in quality. Think the pipedream 400 is a comfort level of -4 if I remember rightly but I've been cold in it at zero

I’ve got a pipe dream. Don’t remember which. VERY snug fit, not that warm and feels cheap. Replaced with a Rab I found in a sale.

Certainly not a racing snake anymore! 6’1” and big, not especially fat but broad. I found it was definitely snug.

+1 for the pipedream 400

Another recommendation for the Pipedream 400. Good warm bag. Not 4 seasons. Have paired with a silk liner, merino thermals and socks, down jacket and slept sub zero at sea-ish level. Toasty
