Reviews

I love the design and functionality of the zip off thermal bottoms!

"The new Marino zip offs are an improvement on the older style. At 6’2” the old style zip offs were short on me. I love the concept but they would only cover to mid calf at best. These fit me much better hitting right at the top of my boot. Also the 200 Merino is the warmest lower thermal I’ve tried yet. These under attack pants were perfect for 20-40deg late season mule deer hunt in Co."

Great Midweight layer

"These are great for layering under waders for super early morning set ups. Or between layers when sitting for extended periods and needing to shed heat as the day progresses. Only thing I dont like is how they fray so easily. Got the velcro strap caught on the leg one time and it pulled a bit of fiber away"

— Tyler S. (4/5)

Great bottom base layer

"For 15 years in the field for the Army I skipped long johns due to the inconvenience of taking off my boots to get the longjohns off when its time to move again. Then I saw my cousin zip his off while on a rocky mountain mule deer hunt and I had to get these. Absolutely a game changer, great for chasing elks and sitting for white tails in GA. I liked them so much I gave a pair to my hunting mentor as a gift."

— Gregory M. (5/5)

Spendy long John’s

"Perfect fit and very comfortable. Other reviews mentioned the side Velcro tabs being a bit bulky and this is true. It’s not annoying but it is noticeable. Wore them on a couple tree stand hunts, 25 degrees, they were nice. I have yet to wear them on a good hike. So far they are worth the sale price."

Excellent

"I punched these for warmth during deer hunting. They are a great pair to own, as they did what they are built for! WARMTH. . . ."

— Mike W. (5/5)

Novel idea poor craftsmanship.

"I initially liked them, but the zipper stitching fell apart two days after wearing them on a mountain goat hunt where gear is critical , I had to use tape to keep them closed. Because they did not work, I ended up abandoning them at spike camp to save weight on charter flight out of camp, because without functional zippers they are garbage, and every pound cost money to fly."

— Austin S. (1/5)

Nuyan Pro Merino 200 zip-off

"I love the fit and added warmth the Pro Merino bottom’s provide. 200 pairs well with Attack pants, for fall cold mornings. The zip-off feature works nice for fast over boot removal. Only one issue an obvious manufacturer defect. The Velcro for the side waste adjustments should be rough side out, smooth side in. Other than that, it’s great quality."

— Jerry S. (4/5)

Awesome warmth

"Love these, kept me nice and warm during muzzleloader season in Ohio 13 degrees!!!"

— Matthew J. (5/5)

Game changer…!

"Not sure these can be designed any better. Absolute game changer for in the field temp regulating and not having to decide before the day’s hunt if you want to wear your thermals due to inability to remove quickly…these change the game!"

— Billy S. (5/5)

Comfortable and Warm

"I bought these obviously as a base layer and they do the job well. I wear 36x36 jeans and they fit just fine. I have not really found a use for the zipper yet but thisnis my first season with them."

— Jacob M. (5/5)

Q&A

Hi just wondering if I wear a hole (ie, knee area, buttocks area), looks like warranty will not cover this, but will I be able to send it in to get it repaired by your "Damaged Item Repairs" service? Thanks
Generally rips and tears are not considered manufacturing defects, but we can recommend our repair partners at Rugged Thread if needed
