      Product Story

      Chugach [chew-gatch]

      Chugach State Park and Chugach National Forest both reside in Southeastern Alaska. Both are quite large and have plenty do to, whether it's hunting, skiing, hiking, fishing, or just taking a scenic drive. Chugach State Park is located just several miles from Anchorage, while Chugach National Park spans much of Alaska's coastline along the Gulf of Alaska and Prince William Sound. These wonderful parks are hugged by the Chugach Mountains to the north.

      Why Merino Wool?

      Moisture Wicking

      Minus33 Merino Wool regulates the amount of moisture on your skin by absorbing any moisture or sweat on your body. Then, the absorbed moisture evaporates out of the fabric into the atmosphere.


      Merino Wool fibers naturally reject any bacteria in moisture or sweat as it is wicked away, so foot fungus and smelly odor will not be a problem while wearing our products.

      Insulates When Wet

      Wool will absorb up to 30% of its weight in moisture without feeling wet or clammy. If you do get wet, wool will insulate you better than cotton or polyester materials.

      Fire Resistant

      Merino Wool insulates against high temperatures and does not readily catch fire. If it does, it self-extinguishes. When Merino burns, it doesn’t melt and stick to the skin like synthetic fabrics do.

      UV Protection

      Don’t worry about sunburn on a sunny day summiting a peak. Lightweight layers have a UPF rating of 25. Midweight and Expedition have a UPF rating of 50+.


      Merino Wool has a low environmental footprint and naturally returns to the elements. Shear a merino sheep in the morning, and in the afternoon they’re happily nibbling their way towards renewing next season’s clip.

      Great for 🥾

      I absolutely love my Chugach Bottoms! They are an easy layering piece while hiking. ❤️🤘🏻🥾

      Headed out for a trip to Kodiak this week. These will definitely be in my pack.

      I’ve been waiting a few years hoping someone would come out with these. I use mine for hunting and it makes such a big difference being able to add a layer and not have to take my pants or boots off. The zippers are very smooth and quiet. At first the Velcro didn’t look very good but it grabs like no other and it’s very quiet. Another outstanding product to add to my other 17 Minus33 products I own.

      A game changer when hunting! Thank you for your review.

      Been waiting a long time for something like this

      Bottom line: I have yet to wear the Chugach Men's Expedition Zip-Off 3/4 Bottoms yet in the correct environment to test their warmth; I've only had them on the day they arrived to ensure they fit, which they did. The short time I did have them on they were very comfortable and upon closer inspection of the product I could tell they were of the highest quality. I'm 5'10"ish at 190 and the Large was a good fit. Follow the recommended fitment- they are a bit stretchy as I expected them to be. I look forward to putting them to the test this November during the West Virginia Antlered Deer Rifle season. I will update after that to give a more in depth field review.

      But one may ask why I've been waiting for something like this as a title to my review. Way back in 1996 when I was a much younger Soldier I was attending the US Army Ranger School during the winter. Believe me it gets really cold in northern Georgia in the winter, especially if your are pretty much living outside 24/7 and not getting much to eat and little sleep. A number of my fellow Ranger students had brought with them modified USGI Army brown polypro trousers that had been modified with hook and pile tape (Velcro in the civilian world) along the outer seams much like the Chugach bottoms have the zippers. They made life for those Rangers much better than those that did not have them- we didn't always have time to don and doff long underwear before each stop or movement especially taking boots off and putting them back on to facilitate long underwear changes. I toyed with the idea of making a pair myself after returning to Fort Drum, NY but just never took the time.

      Similar situations occur in the hunting woods where the morning starts really cold but by noon it has warmed and you no longer need the layers and not many hunters want to remove boots to remove layers. These are a welcome addition to my layering clothing. I look forward to many years in the field with these. Thanks Minus33 for a great product that I've been looking for over many years.

      These will make dropping a layer as it warms up so convenient. Thank you for the great review.
