Whether you pulled a late-season elk hunt or are down to the closing bell in the treestand, First Lite's Furnace Long John is the perfect tool to help you punch that tag in cold weather. Using our Merino-X 350g EXP weight fabric, the Furnace Long John provides lofted insulation and protection from the coldest temperatures. Featuring flatlock seams, a brushed, jacquard waistband and an articulated fit, the Furnace Long John leverages the loft, structure and stretch of our Merino-X fabric to provide the ideal layering piece over our other lightweight, next-to-skin styles.This system is the new standard for stationary hunts or late season stalks when staying warm is critical to success.

Our Furnace EXP 350 Merino-X fabric incorporates a brushed (or fleeced) backside to our high loft, interlock knits to provide super-charged insulation without added weight. Adding this to the silent, odor-free benefits of merino wool, the Furnace merino is the hands-down choice for cold weather hunts.

The Furnace EXP 350 is also available in Henley and Quarter Zip Tops.

Excellent Product

I've used these in both active and stationary activities in 20deg weather and my legs were always comfortable. Not too hot and not too cold, just the perfect temperature for whatever I'm doing.

Great quality great warmth

These long johns fit great, feel great, and are extremely warm. I wouldn’t hesitate wearing these in to the woods in any temps with just a wind stopper pant. These were part of my first First Lite order and I am impressed.

Great buy

If you don’t do well in the cold you would do well to own these! I purchased the long johns and quarter zip top and couldn’t be happier with these base layers.

Great long john

These long johns are super comfortable and incredibly warm. They fit true to size. Nice and snug so they can fit under any other pants, but not crazy tight so that they are uncomfortable. Only negative is the waistband has worn out after only 2 seasons of wearing them. They sag a bit, but I make due, not enough to make me regret buying them. Have an older pair of other First Lite long johns and have not had the same issues with the waistband on them.

The furnace long john and furnace Henley are the warmest base layers I’ve ever wore. The products are excellent quality. Wore them in the stand with temperatures in the 20s with a mid layer and bibs stayed very comfortable even with snow falling.
