Built as the foundation of a high-performance layering system, the Deep Space Base Layer Bottom delivers next-to-skin warmth, moisture control, and all-day comfort across changing conditions. Designed for active movement in cold weather, it regulates temperature while keeping moisture moving away from the body during hiking, hunting, travel, and everyday outdoor use.

Powered by FORLOH’s exclusive Trizar™ technology, originally developed for aerospace applications, the fabric captures body heat and re-radiates it back toward the wearer while maintaining breathability and quick-dry performance. Integrated scent control helps maintain freshness during extended wear.

100% sourced and manufactured in the United States.

Constructed from a durable polyester and spandex performance knit, the Deep Space Base Layer Bottom balances stretch, durability, and moisture transport for next-to-skin comfort.

Flatlock seam construction minimizes bulk and friction, creating a smooth layering experience under outerwear and insulated systems.

Reviews

Warm under the right conditions

"Here is my experience with the Deep Space bottom. These are warm when worn under hiking pants and doing something. They feel cold when exposed to the wind. They also feel cold when not doing anything, like hanging around the house and worn under sweatpants. The construction (seams, stitching) is great - no flaws I can see. They were a little tight at first, and stretched out after a couple wears."

Warm but slide down

"Don't stay up, slide down within 5 minutes of walking. Just stick with merino wool, way better."

Chris (1/5)

Comfortable

"This base layer is incredibly comfortable and soft. They keep me warm and dry. So I bought more."

Jeremy (5/5)

"They are really well made and comfortable"

Cody (5/5)

Returned

"Returned too short in legs. . just bought all clima pants and again clothing seems to be designed for small men… hunters are traditionally bigger men"

Richard W. (2/5)

Great feel

"Great feel"

Well made. I wore them

"Well made. I wore them in temperatures ranging from the mid twenties to the low 50’s and was comfortable (temperature wise). Fit was true to size. HATE THE SEWN-IN INFORMATION TAGS!!! The stack of garment information tags sewn into the right leg seam itches and scratches like crazy. I had to cut them out. I recommend that you come up with a better solution than the sewn in tags. If they must be on the garment, sew them on the outside of the waistband at the back. If it weren’t for the irritating tags, I would have given the garment 5 stars."

Rick M. (5/5)

Great product. Keeps me warm.

"These things are awesome!!!! I used them while ice fishing. The temperature was around 10 degrees. Can’t wait to try them out under my waders. I’m 5’7” 170 lbs and went with a small to start with. They were too small. But the return process was simple. And I had my new pair of mediums in no time."

FORLOH for LIFE

"I'm a fanboy. All things FORLOH make me crazy. Now, my wife is on the team. She's hot as a 2 dollar pistol in "base layer" aka mountain lingerie. . ."

Q&A

What is the fitment supposed to be like on these thermals? I went by the size chart and they are supper tight and seem short. I bought medium. My allclima pants are 34 waist and they are a little big so I thought medium would be a good fit for the deep space pants.

Are these a lightweight, midweight or heavyweight? Trying to get a guage for temp rating. Would be using them for temps below 32 degrees.
