Most silk insert brands will be pretty similar on how they help keep you mostly cool during the night (like Elle Silk, Mommesilk, LilySilk, THXSilk, Daniadown, Ocochi, etc) but only have some variations in the outershell or how much silk fill is in it. Personally, if you're getting a summer weight the grade of the silk doesn't really matter much since ALL summer weight silk inserts will be boxstitched together, thus negating a lot of the reasons for having long-strand silk floss in the first place, so keep that in mind when you shop. I know that THXSilk has less silk fill in their silk inserts compared to most brands, so if you sleep much hotter than most or your room temps are particularly high then it definitely helps to keep track of how much silk fill is in each brand's summer weight versions and go from there. Depending on how much silk fill you want (less for more cooling properties, more for more heat retention) or what type of outershell material you want they'll all pretty much be similar enough to where it won't matter much in the long-run, imo. THXSilk I think has the nicest outershells that are cotton (6A and 7A versions respectively), though I want to be clear: all of the brands I listed will be pretty great quality overall and you'll be nitpicking most brands against one another. I love my all-season silk insert because it's pretty heavy and it was cheap as hell for what it does (which is keep me mostly cool at night in temps of up to 74F), but if you don't have AC and you live in a hotter part of the world I would definitely just go with a summer weight silk insert that has a lower thread count for its outershell and less silk fill to ensure you get the best breathability. Personally, I wish most silk insert brands used linen outershells but they're too expensive for most and I suppose most wouldn't like the rougher texture if they're not using it inside of a duvet cover, so... sigh we'll likely never have one unless it's a handmade one from Etsy :( If you have any more questions feel free to ask :) More on reddit.com

The highest quality mulberry silk is Grade 6A. For sheets and pillowcases you want a 22-26 momme. Anything more than that is better for curtains. The best mulberry silk you can buy comes from St. Genève because it’s made at the best textile plant in the world, but it’s pretty expensive. I’d recommend buying Grade 6A mulberry silk from Fisher’s finery or Slip. Slip is a little more expensive but both offer some of the best quality for the price and are widely reviewed. Yes, more of that is bought and paid for, but having gone through numerous reddits and feeling the material for myself, stick to the brands I mentioned. Good luck! More on reddit.com

I bought the THX Summer 6A in February of this year. Im also in the Midwest and sleep pretty hot. I loved it in winter, I did layer a cotton waffle blanket (along with a top sheet) and it was totally perfect, super cozy and I never woke up hot. Now that we’re in summer, I’ve been sleeping with just the top sheet, and the silk comforter on the lower half of my body, and it’s been pretty great. I keep my ac at 60 degrees, so it’s pretty cold. I heard the THX was thinner than the Mommesilk, so went with that. I like how soft it is but still has some weight to it. I do wish it was more fluffy, like a down duvet, but I don’t think you can get that effect with silk, More on reddit.com
