Every piece of clothing I've bought from standard issue is my favorite, but this stands as one of my best purchases in a while. It looks great and you can wear it often here in California.
This is one of my comfiest, most complimented piece of clothing…They run a little big so I sized down to a medium - washed and dried a handful of times and hasn’t shrunk or lost an ounce of quality…This thing feels like your emotional support hoodie you’ve worn a million times right out of the bag. And this color? Antler?! Love. 10’s across the board! 🔟🔟🔟
I love these thermals!!! A cropped version would be awesome too!! Def need more colors
Pay attention to sizing! Slightly BIGGER than the chart. The fabric is really great. I have thermals from Iron Heart and these are better imho
This is the best thermal sweater I have ever owned!
High quality and heavy duty 100% cotton, feels great for lower temps or the gym where you need to warm up quickly, but also just a great solo piece.
The fabric is great, but the sleeves (at least on size L) are short. Too short.
great product
Nice weight, great material
great quality
Love it
Really good material when you put it on it feels cold but after a couple minutes it get warm like it has some kind mechanism love it i highly recommend.
Nothing to dislike. Good quality
I was not impressed by this item. While it is heavier than a typical thermal shirt, the weave is not dense and the fit is awkward. I would purchase the return insurance if you’re on the fence.
The game is changed with thermal shirts. The best hands down!
love the color
Absolutely love the heavyweight thermal sweater. Thick, substantial, and warm without being too bulky. The material feels high quality and holds its shape really well, even after multiple washes. No shrinkage. Fit is spot on. I’m a more fit build and usually have to be careful with sweaters either being too boxy or too tight. Im usually a small, or med in 100% to account for shrinkage, and I went with an XS here. It hits that perfect in-between. I've since purchased nearly every color. Between this and their customer service, SI is going to put me into debt.
These shirts are thick well sized roomie warm but not overbearing and i absolutely love them
Thick as hell soft thermal great
Great quality!
Very quickly becoming my favorite shirt perfect good warmth loose but snug I love the design and everything about it
Super comfy
Super nice and heavy . I sized down and should not have, so do not follow the disclaimer if you’re not sure . I ordered XXL this week so I can have one that fits better; I can still wear the XL but I was definitely disappointed in myself for sizing down because it fits a little short . Great product !
I bought two of the thermal sweaters and unfortunately had to return them both - I started with a size L, it was too small so I bought two XLs that were also too small (in the arms). The quality seemed high just not a good fit and the arm lengths in the XL sizes were also not the same.
Husband loved them!
Great feel
A great shirt but the sleeves are much too short. Unfortunately it will have to be returned.
Quick exchange made it simple and painfree! Love this sweater!
Dope material not itchy good for cold weather .
nice quality, looks great, nice fit.
This thermal sweater is simply outstanding - I love it - the quality, the fit, everything!!
great quality. runs large. would size down.
Quality materials, heavy and deep, textured color.
Staple piece, buttery soft. What more could you ask for?
Great quality, but sadly the recommendation to go down a size does not always apply and now my teenage son is the proud owner of my two thermal tees 😢
Bris H review made on 11/28/25 has to be the most comical but truthful review. Hands down had me dying. 🤣 Best, Robert
I enjoy every single thing about this garment except for the short sleeve length. I’m 6’5’’and have really long arms. The sleeves are too short for me. It fits perfectly every where else.
I have worn it nearly every other day since it arrived. LOVE this thing for layering and hanging out in a chilly house. A+ and a bag of chips.
Lowkey get compliments on this all the time lol. Knit is visibly thicker and higher quality when put against other waffle knits. The guy in the pictures is a bit lanky but I’m shorter with a more athletic build ( 5’9 165lbs) and it outlines my frame nicely! Wraps around the arms and chest w a slight bag in the waist which is exactly what I was looking for.
