Men's Furnace Long John

EXP 350 Merino-X

$110.00 USD

Color/PatternFirst Lite Fusion

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.

Amazing

These long Johns are perfect for cold weather tree stand sits in Ohio. Matched with a pair of merino pants and my legs were comfortable the duration of the hunt. Highly recommended for all outdoor activities in the cold weather.

My upgrade from the old exp 350 from years past

Awesome stuff. I have wore this now on 3 hunts with just the sawtooth brush pants over. Coldest morning 31 degree start. Hotest afternoon 62 in December. Right! Southern Indiana. Alot of still hunting thru brush an big hardwoods with the muzzleloader an comfortable all day. Love it! It was just a little long on the inseam but not any issue at all with that. Wrinkles up a bit.

Very warm mid layer

I got the Furnace top and bottom to add onto the Fuse base layer on those colder sits later in the season. So far, it has lived up to the hype, and I am REALLY liking the quarter zip top. Very comfortable, virtually stops the wind, and allows me to sit on watch that much longer. I do wish I had ordered a size up on the top for layering over the Fuse, as I'm right on the cusp between just right and it being too tight. Bottoms are perfect. Definitely a great item to have for those late season hunts!

Keeps you warm!

Wore them in -8C for a few days with some sawbuck brush pants, was plenty warm when sitting and didn’t over heat while moving.
