  • Perfect thermal underwear
Special Size Type: Standard Weight Size: Small Color: Navy
Exactly as advertised. I've purchased from this brand 5 times now, and every time, it's wonderful. They're comfy and durable.

  • Cold weather
Special Size Type: Heavyweight Size: Medium Color: Black
Used this long Jhon heavy weight thermal set in Iceland during my vacation. It is very comfortable and saved me from Iceland cold. I recommend this for cold weather

  • comfortable
Special Size Type: Heavyweight Size: Large Color: Melange Charcoal Grey
This is good looking, soft and comfortable and a good fit. It is not what I would consider as heavyweight which accounts for the this slightly lowered evaluation.

  • Warm enough?
Special Size Type: Heavyweight Size: Medium Color: Melange Charcoal Grey

  • Great baselayer to wear under drysuit for kayaking
Special Size Type: Standard Weight Size: XX-Large Color: Black
First, I'm 5'7", 250 lbs, 38-40 waist, 50 inch chest, XXL fits well and comfortable, though the sleeves and legs are a bit long. Not a big deal, they can be bunched up. The Fleece lining is very comfortable against my skin. I wear this under my drysuit. While in the water I found the sleeve of my drysuit had a leak. As the cold water came in, the sleeve of this base layer got pretty wet. The wet sleeve felt cold, but it still kept me fairly warm and didn't absorb much of the water, helping me to stay warm. The rest of me stayed comfortably warm in the 40° water, even though the drysuit itself didn't do much for warmth, it just kept me dry. **UPDATE** I have now worn this for three sessions of rolling practice in my kayak. I still have a small pinhole leak somewhere in the back panel of my drysuit, but it doesn't leak too much so I don't worry about it. This baselayer is still keeping me warm as the only thing I'm wearing under my drysuit in 45°f water, even when slightly damp. This isn't just while sitting inside the kayak, but also while submerged upside down and while swimming during a wet exit. This really is a great mid weight base layer, and one that any kayaker should consider for under their drysuit! If you're going to be in water any colder than this though, especially if the air temperatures are cold, I would recommend doubling up layers and either wearing a second set of these or getting a heavier layer to wear over them. Overall, this was a great buy and a much cheaper option than other base layers. I would definitely purchase this one again! -Piper's boyfriend :-) ... show more

  • Quick to process, but slow to actually ship!
Special Size Type: Standard Weight Size: Medium Color: Navy
This is the most comfortable underwear I've ever worn, but for some reason it takes this product longer to actually be shipped than anything else I've ever ordered through Amazon!
