Aegismax - AIR 10D 800FP Ultra Dry Down Sleeping Bag Ultralight

Aegismax air, £70 with a voucher, in the recent sale on AliExpress. 260g of 800fp down so temp rating should be about right.

Are you sure you wouldn't be better with a cheap (like really cheap) blanket at this point? It's 630-640 CUIN duck down (seems like 90% down / 10% feather), non-compliant to RDS. The temp rating is said in one place +15 C, in other 0 \~ +5 C with no temp rating standard (the standard they wrote is a chinese standard of naming down products and paramaters of the down, not the temps). It has 185g of the down filling. At least the CUIN/FP isn't boosted by adding hydrophobic treatment. All assuming that the baffles are of correct size (never used Ice Falme bags, but I have one pretty light Aegismax Air 10D and it's dramatically underfilled with empty spaces between the down introducing cold spots in the night). Just to compare the numbers with some similarly rated bag - Pajak Radical ULZ (about 240 EUR on sales) specs: Fill weight: 160g Fill: 900 CUIN goose down (95 down / 5 feathers), RDS Temperatures (EN 13537, ISO 23537): Comfort +5 C, Limit 0 C, Extreme -15 C

They seem heavy and bulky. I use an aegis max wind hard from AliExpress for summer about $160. Looks like there’s an aegis max square down bag with 10D nylon that’s decent for $100. You sure a 30 degree bag is right for summer? Usually people use 40-50 degree bags and buffer that temp with a down jacket or thicker base layer. Edit: Found a different one: [$120, 800fp, 50F comfort, 370g (13oz)](https://iceflamegear.com/product/semi-summer-nxt/)

The obvious is that your sleeping bag is about 2lbs heavier than it needs to be, but replacing it with a decent bag, even a Chinese direct bag like Aegis Max or Ice Flame will consume most of your budget. I assume you're attached to a 2p tent for bringing the little? I've started dreaming about taking my 6yo on trips some day, but I can't imagine asking a kid to sleep under a tarp, (or dealing with a cranky kids who didn't sleep well because he/she was under a tarp) and you probably don't want to invest in 1p tents ... I have experimented with using a poncho as a door (and vestibule) for a tarp or shaped tarp. With the kid, 2 ponchos means 2 doors and the tarp becomes much more of a tent. Ponchos are also lighter than your listed rain gear. If you want to try a tarp and bivvy, oware/bivysack.com has some decent winter sales running right now. Why a puffy and a vest? Is 1 or both of them a layer you could replace with alpha and a wind shirt? Or just a cheap 100 weight fleece? The Dooy Sun Shirt is the current go-to budget windshirt on Amazon. I like mine, though it isn't really tested yet. IMO they fit a half size small, or just a little smaller than an athletic fit, so I happily sized up. There are "reactor" fleece shirts on AliExpress that are just being discussed as a budget alternative to alpha but they're pretty new to the scene I'm also a side sleeper, I can't do just a CCF pad, but I strongly believe much of the hip and shoulder pain actually comes from insufficient pillow. I use about 8 inches of pillow, with one of the tallest inflatable pillows (from Big sky, but there are decent cheap pillows on Amazon), on top of my food bag and other spare stuff. I use a very thin inflatable pad (Klymit x frame) cut to torso length, and 1/8" CCF full length pad under that. Though (in the interest of you budget) I did a proof of concept with the sleepngo inflatable pad that's like $12 cut to torso length.) bears These suggestions are all pretty low on r value.

Aegismax from aliexpress are the best. in the lower price range from my experince,
