I have Just ordered a AegisMax M2, if your guna buy Chinese crap, buy it direct haha. Ali Expres has them cheap as chips and free shipping.(cost me about 150NZD)
Its listed at around 600 grams, or 1.3lbs(21oz). Rated to around 2-3 Degress C, around 30-35 F I think.
For summer it should cut the bill(here anyway), they seem to have good reviews online which is pretty surprising.
Aegis Max has a full range of bags and quilts at dirt cheap prices. I have been looking at them for a while, and reviews seem pretty good actually. They are cheap, Chinese, but good value for money it seems. They do use 800 loft down and most reviews think the temp ratings are accurate(the do supposedly have EN ratings). One thing all reviews say is to down tech wash them as soon as you get them and they are way better. Id say they have been stored compressed long term.
If it seems shitty I will probably order a Nitros from One Planet, same weight and rating more or less and around $400 AUD.
One Planet make good solid gear.
Depends on temps, but I think you should be able to get a bag around 500-600 grams(1.3-1.5 Lbs) with a rating of just around freezing, depends how cold you sleep and where your hunting, for here its not often close in the summer/spring(odd night might be close at high altitude), with a light down puffy you should get by.
Will do a review on the Aegis max experience after this summer haha.
Pad wise I use the small ThermaRest Neo Air, the half length one. Im 5'10" and its kind of knees to shoulders length. In warm weather its great, in cooler weather I use my sit pad under my lower legs(or my pack). I use this pad all year, and in the winter I do notice it beeing cold, but usually just put a closed cell foam pad under it. Mine weighs 235 grams/8.2 oz in its stuff sack
