  • Easily the best choice for a shirt that keeps you warm and isn’t bulky. Also soft and cozy.
Team Name: Thermoflux 200 Midweight Athlete: 2 Pack Size: XX-Large Color: White 2 Top
Female 38. 5”8 245lbs. Bought 2X Sorry it’s been 2 years, I rarely write reviews but I just dug this out the attic and omg where has this been all my life? (Other than the attic). Someone with autoimmune conditions and can get hot in a matter of seconds and then ice cold I can say this sweatshirt is my new best friend. It’s lined with warmth but still pretty thin comparatively. It’s shape fitting so it hugs you in all the right places. It’s soft inside and out. I wore it 2 years ago in Montana where it’s cold and it was an under layer. No complaints. I live in Florida so naturally this thing went into the attic. Found it in holiday decor and put it on bc we’re having a short cold snap. It’s amazing, thin and soft but still double lined, fleece on the inside. Didn’t shrink much in the wash. Price was about the same as other thermals but this is by far better than any other thermal shirt I’ve ever owned. And no I didn’t get any incentives for leaving this review. Will purchase multiples. Wish there are more colors. ... show more

  • Really nice!
Team Name: Thermoflux 300 Heavyweight Athlete: 1 Pack Size: X-Large Color: Camouflage Dark Gray
I’m 6’5 225 lbs and the XL fits perfect. Nicely warm and long! Sleeves are perfect length and the shirt hangs down well below my waist. Most don’t so very happy with the cut of the shirt. Very soft short fleece inside. Going to order more!

  • The warmest, lightweight underwear I have ever worn.
Team Name: Thermoflux 200 Midweight Athlete: 2 Pack Size: Medium Color: Navy Blue 2 Pack
Lightweight, nonrestrictive to movement, yet fits tightly around body. The fleece lining is like a warm blanket against your skin. The best base layer I have ever found. Whether you are going to be active outside all day in 30 degree temps. with wind or just a little extra protection from temperate conditions, just add the appropriate layers. A well made garment, looks like it will last a long time with proper care. Easy wash, cold water, gentle cycle, low heat drying. I wash mine inside out because the fleece needs to be "fluffed-up". The only draw back that I can see is the sleeve length. The cuff wants to draw away from my hand. I feel the need to keep pulling it down all day because the rest of my arm is to warm. ... show more

  • Camo shirt
Team Name: Thermoflux 300 Heavyweight Athlete: 1 Pack Size: Large Color: Camouflage Dark Gray
I bought the thickest of the three thicknesses available. Very comfortable shirt . Great for fall weather and not to bulky to hike in. I’m 5-10 and 175 and a large fits well . Mb on the long size a little.

Got this for my teenage son for those cold nights at football games. Super soft and warm. Works great for under his uniform.

  • Warm, Great Fit and Comfortable Vibrant Colors
Team Name: Thermoflux 200 Midweight Athlete: 2 Pack Size: Medium Color: Camouflage Green 2 Pack
I sought out these thermal tops for both me and my husband since we are both veterans. These shirts fit great. They are very comfortable, made with sturdy material and the price was good. I love the fact that the sleeves to all the way to our wrists. I wish they had these in solid colors so I could purchase a few more of them. A comfortable well-made thermal shirt and a great buy. I would definitely purchase again. ... show more

  • Quality/value has slipped but still decent
Team Name: Thermoflux 100 Lightweight Athlete: 2 Pack Size: Small Color: Light Grey 2 Pack
I bought the size medium in 2019, more slim fit at that time, inside had a soft, velour texture. (My dress shirt size is 15 1/2, 32-33) Bought again Dec 2022, had to size down to a small & still not slim fitting. Also material is thinner, doesn't have soft feel inside. $30 for two. Not a great value anymore. ... show more
