  • I don't know how LAPASSA does it!
Team Name: Thermoflux 300 Heavyweight Athlete: 1 Pack Size: X-Large Color: Dark Heather Grey
How do they consistently provide such durable, comfortable, high performance products at such an affordable price? I wore these Thermal Underwear Bottom Long Johns Pants under thin joggers in 30 mph wind in single digit blowing snow conditions. They felt so comfortable and I never got close to feeling cold. ... show more

  • Toasty! Great fit.
Team Name: Thermoflux 300 Heavyweight Athlete: 1 Pack Size: Medium Color: Dark Heather Grey
These are for temperatures below freezing. I slipped a pair of breathable golf kakis over these and play when the ground is frozen. The waistband comes up to my belly button allowing me to tuck in a long-sleeve water wicking tee shirt in deeply and put on a lightweight hoodie that falls over the underwear and pant waistband sealed by a lightweight shell. I pull the underwear over my sox. Everything stays in place the higher waistband rides higher then the pants waistband preventing bunching. I love these! I returned 3 other brands for size, nonwarmth, low waistband that bunched and serious shrinkage. This underwear is exactly how I would design it. Perfect! ... show more

  • Great Thermal Underware
Awesome fit, I wear a 32 waste, and the medium fit well, but provide room for movement. There light weight, and provide great warmth. They launder well.

  • Very thick, warm and comfortable.
I love them! Bought two pieces of the tickest kind available. I use them everyday under my regular pants when riding my motorcycle in winter weather. Will buy some more when needed. Very recommended item. Worth every dollar I paid for them. MC

  • Sizing is completely wrong to the point of being unusable.
I'm a 5'11" lean, weighing 192. Normally , men's size large pants are rhe right fit or 32x32 or 33x32 in jeans. I followed the other reviews and ordered medium which is a size down. Medium fit baggy and floppy in the legs and went two inches above the belly button. I returned the medium and ordered a size small. Size small is workable but not great. It's still too loose. I would order X small if they had it. These don't fit like tights or workout tights even in size small. I don't think they are usable for a run or biking. I can probably make it work for snowboarding or wearing under jeans in single digit Temps. The quality of the material is good and interior fleece is nice but the sizing and fit is so screwed up its hard to know what these are for and make it work. ... show more
