The CL Convallaria Long Johns Thermal in size Large performed exceptionally, earning a rare perfect rating for their primary function: insulation. This garment is not merely a pair of long underwear; it is a dedicated piece of cold-weather gear. Superior Warmth Retention: The internal fleece lining is the core strength, providing immediate, soft warmth the moment the garment is put on. It effectively traps body heat close to the skin without relying on excessive bulk, maintaining comfortable body temperature during prolonged exposure to cold and freezing conditions. Excellent Base Layer Integration: Despite the fleece, the material is engineered to be lightweight and low-profile, ensuring smooth integration under jeans, trousers, or heavier outdoor gear without feeling restrictive or adding uncomfortable volume. The size Large offered an ideal next-to-skin fit, crucial for maximizing thermal efficiency. Active Comfort: The fabric incorporates moisture-wicking technology and 4-way stretch, a critical combination for base layers. It actively pulls perspiration away from the skin, ensuring the wearer remains dry and avoids the cold, clammy feeling associated with traditional cotton thermals. The flexibility ensures a full range of motion, making it suitable for active, dynamic cold-weather sports. Design, Fit, and Longevity The size Large proved true to a standard, non-compression fit, providing a comfortably snug fit throughout the legs and waist. Construction: The attention to detail, particularly the use of flatlock seams, is commendable. This feature eliminates chafing and rubbing, maintaining all-day comfort, whether worn casually or beneath heavy work layers. Softness: The ultra-soft quality of the fleece lining is a standout feature, creating an incredibly pleasant tactile experience against the skin that often lasts through many washes, surpassing the comfort of many standard thermal sets. Durability: The blend fabric feels robust, capable of withstanding the wear and tear of physical activity and repeated laundering without pilling or losing its insulating capability. Conclusion & Recommendation (5/5 Stars) The CL Convallaria Long Johns Thermal is a highly recommended purchase for anyone prioritizing warmth, comfort, and functionality in cold environments. It delivers high-end performance features—superior warmth, effective moisture management, and non-restrictive comfort—at an accessible price point. This thermal garment is an essential investment for: Hunters, Ice Fishers, and Winter Campers Outdoor workers with extended exposure to the cold Anyone seeking a reliably warm and comfortable layer for daily winter wear.

I really like these thermal underwear soft fleece. I love the neck. It’s not really a turtleneck but it’s kind of a turtleneck snug and nice and warm. I love these that I had to return them because. I got a a size 2 small. I got a large when I should’ve got an extra large. The bottoms were a little tight on my midsection so I regretfully had to return them now I really need them, but they were just still a little too tight on the bottom, but these are the nicest long underwear that I’ve ever had and I’m going to buy the larger size (just sayin) Read more

Good quality. But I need to return a set of four garments because the interpretation of the size on the chart is misleading. The size of the waist is the same as dress pants. I ordered 2XL/waist size 32 inches. I have reordered another set of four two sizes down (from 2XL to L) because the thermal pants is elastic and stretchable. I hope that the manufacturer understands the differences and corrects the size chart so that unnecessary returns will be eliminated! Update (12/22/2025) - After receiving another set with two sizes down, they are snug fit perfectly. I purchased them as my sleep wear in the winter. They are warm and cozy!👍❤️ Read more

I ordered 2 versions. The 2X large heavyweight version and I believe it’s called the lightweight. The heavyweight version was way too small and does not stretch at all. It felt like I ordered a medium size instead of 2X, so if you get the thicker version make sure you order a couple sizes bigger. I’m pretty tall and weigh 280 lbs easy and can comfortably wear 2x all day. The size chart is kind of misleading to me because it doesn’t specify for which version you’re looking at. Now the 2X version was exactly what I needed and with it being way more stretchy I could’ve easily ordered the large or XL. After washing, it does not shrink and so far the color will nor fade or I don’t think it ever will. I feel like it’s durable and would last as lifetime. I like the inner layer, it feels soft and warm and has not made me itch. Read more
