Great midlayer for cold Maine mornings. Not so heavy that I sweat it out on my way to my stand. Great under layer for snowmobiling as well.

Fit was spot on for me in my layering system.
The Furnace Quarter Zip is the perfect heavy-weight mid layer while your outdoors.
This mid layer shirt kept me warm and comfortable on those frosty mornings while glassing.

I like this pull over, comfortable and warm

If you need to stay warm this is the mid layer for you. It is heavy but in the best way. I have not used it a ton yet. But now that the days are getting colder, I won’t be hunting without it in my pack.

Excellent article. Fits slightly big so I downsized to a medium, the M is perfect. I would like to see First Lite make this with a hoody option, with maybe even a 1/4 zip. Warm, cozy and great base/midlayer.

Size. Fit. Comfort. All perfect. Heavier without bulk, but still heavy enough to layer with on cold days.

This is just as good as everyone writes. I bought the whole line in specter in XL but this was the only piece I had to send back to exchange for one size down. Still great product and the quality is spot on and it is very warm.

Got the Furnace as an early birthday gift. I was very surprised with how thick it was. It also has a smooth interior, making for a very comfortable fit even with my Fuse long sleeve under that. One of my concerns that I had immediately out of the box was the sleeve length, bc FL makes their sleeves way too long (in my opinion). However, the sleeve length on this is actually a perfect fit for me. I have not worn it in cooler temps yet, but I can see me using this as an outer layer a lot. I would recommend ordering a size smaller than your normal.

The pullover is very soft and warm. Perfect fit and is built to last. The 1/4 zip is nice a big to help dump heat when walking . You won’t regret buying this.

I bought this for my dad. He loves it. It’s lightweight but retains great warmth for its weight and thickness. The size is just right. I bought it in Specter and it looks great for northern Wisconsin. While he hasn’t had it long enough to challenge its durability, it appears well made and tough.
