Reviews

Don’t buy Kuiu

"This review is for Kuiu since they won’t let me rate their packs without buying another one which I won’t do. After spending as much as I did on a pack the thing should last more than 2 seasons of use. Kuiu’s lifetime warranty covered the frame only, and left me with a worthless bag and hip belt with no ability to replace the frame since they stopped making it. They wanted me to buy a whole new system with effectively 15% off. This will be my last Kuiu purchase."

Easy

"In a Colorado hunt for elk, I double layered merino wool in morning. I was able zip off top layer before I started to hike (as sun became warm ) with ease and not removing boots! It was cool!"

— Todd G. (5/5)

Great product, wish they thought of tall peeps

"Wish they offered longer lengths, but these are a game changer for keeping cooler/warm in the backcountry. Sub 30 second removal or putting on without taking boots off? I don’t know how you can beat it. Super cozy too the fabric is very nice as a base layer, not itchy and nice against skin!"

— Ryan Q. (4/5)

Amazing System

"Great system—warm and very comfortable to wear. I put them on in the Alps after the climb, and the fact that you can just pull your pants down, put on long underwear, pull your pants back up, and keep going is simply brilliant. Thanks"

— Elias S. (5/5)

Fits Perfect

"I bought the XL, my jean size is 36 waist 32 long and these PRO Merino 200 Zip-Off Bottom fit perfect. Perfect around the leg and perfect lenght. Very comfortable."

— Jorge M. (5/5)

Glad to have gotten them

"Glad to have gotten them at half price. Do not like the material or fit as well as the First Lite Kiln 250. Seem to have a very low crotch, and the length is a tad short."

— Kris D. (3/5)

Zip off long underwear

"Zip offs are amazing. No longer need to take everything and boots off to get out of long underwear. Love it!!!"

— Aaron W. (5/5)

Super comfortable

"Bought these for an ibex hunt in Kyrgyzstan. With mild temps and early success, I never got a chance to wear these in the field but they served me well pajamas at spike camp. Looking forward to hunting in some cooler temps and putting them to the test."

— Fran A. (5/5)

Great base layer

"These are the best thermals, very breathable and warm when needed. The zip off without having to take off pants and boots is a must. Just know they don’t go all the at down to your ankles 6’3. 5” 250#. XL"

— Tim H. (5/5)

Effective, Easy

"The side zippers perform supremely, the fiber is soft, and the heat retention is excellent."

— Eric B. (5/5)

Q&A

why is the length of these so short (30”)? A large or extra large male average size leg length would be 32”-34”. An option for ‘tall’ would be appropriate, which really would only be average length. I have a 34” waist and 32 to 33” length, so I’m guessing a medium tall would be needed. I purchased a large and they are a bit baggy around the crotch and too short in the length.
They are a 30" length as they are designed to stay over the boot
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
