Midweight Breathable Warmth
When you want to stay toasty on active outings but don’t want to start a personal sweat sauna, pop on the Celeris Midweight K2 Long John. Specialized Verso Weave™ fleece with extra-breathable panels keeps just enough heat while kicking out built-up sweat. Layer it over the K1 or wear it next-to-skin as a midweight baselayer.

Double-knit Verso Weave™ fleece uses a circular grid pattern to create air channels, funneling moisture up to the smooth exterior to quickly evaporate and leave you warm but dry.
The Ballhalla™ fly keeps you comfortable all day long with anatomical support and minimal bulk, and the unique design ensures easy access even while wearing gloves.
A Leg Up
Lighter mid-leg fabric with seams mapped above and below the knee deliver increased breathability and articulation, keeping you sweat-free and moving with ease.

I'm in Juneau, Alaska and have been wearing base layers for skiing, climbing, etc. for years. For winter conditions (15 - 35 degrees F), this is the best layer I've ever had. Well made, strong waist, comfortable/soft material, and easy access for pit stops. I only wish they also offered it at above the calf for skiing!
Best long johns I have used to date. Excellent warmth in sub 30F weather, but didn't cause me excessive sweating while exerting myself. Flexes well and does not bunch up.
Took the Celaris K2 long John camping last week with nights around 35 degrees and it kept my legs warm. Fit was great and wasn’t hot during the 60-70 degree days.
Worked well under my shell ski pants this week. Temps ranged between the mid teens to low 30's. Fit was spot on and very comfortable. Very happy overall.
Excellent for extreme cold weather. Underwear area feels slightly thicker and the waistband is robust. Calf area is slightly more baggy than a traditional thermal under layer. Actually better for socks and boots. Overall great and I’d buy again.
