Our Analysis and Test Results
The Icebreaker 200 Oasis didn't necessarily wow us with any fancy bells, whistles, or tricks, but proved itself as a consistent and dependable workhorse. A snug and traditional base layer fit paired with comfortable and stretchy Merino wool regulates body temp well, wicks and dries quickly, and is a perfect weight to provide versatility through the changing seasons. On the expensive side, it's a hit on the wallet but performs well.
This top is a great weight for a base layer, which means when layered underneath warmer layers it allowed us to trap heat and when things got steamy it kept us comfortable and dry. This model can do the job in really cold situations with proper insulating layers, but there are warmer alternatives if that's important.
We skinned 6,000 feet up Mt. Hood in the bitter cold, and it kept us warm on the static parts of the climb without allowing us to overheat. This has been a tried and true go-to for years of guiding backpacking in the backcountry and has accompanied us on many an international trip. The versatile ability to keep you warm in colder temps but a great weight for not overheating makes this a workhorse. A solid score for warmth, this will serve you well resort skiing in December as well as hiking in October. Not the warmest but sufficient for most conditions you'll find yourself in.
Scoring relatively average among tough competition in breathability, the Oasis does a good job of wicking sweat away from the skin and drying quickly. The tighter weave of the Merino wool offers some wind resistance while keeping admirable breathability.We've taken this top backpacking in February and climbed Mt. Hood in January. It was able to breathe well enough and helped keep us dry while skinning 6,000 feet up Hood and kept us warm at the windy summit. This one of the all-around highest performing midweight tops on the market.
Comfort and Fit
The 100% Merino wool is stretchy and soft next to the skin. We noticed a little bit of an itch for the breaking in period, but after some use and washes, it went away. It has a snug fit through the body and arms, a very traditional base layer fit.
Flatlock seams, offset shoulder seams, and gusseted underarms are helpful when considering use and mobility. If you are on the taller side, the torso and sleeves could use a little more length; there is a little belly and wrist exposure when reaching above your head. All in all, a very comfortable base layer with a fit that may run on the smaller side, good mobility, but not the best for taller folks with long arms or torso.
Here's some exciting news! This had the fastest drying time of any 100% Merino wool layer and dried as quickly as some of our lightweight synthetic options! Drying only a few minutes slower than the fastest top, we were very impressed — some similar weight options were 10+ minutes behind the Oasis 200.
Merino wool is not famous for its durability but with that being said, Merino has come a long way in how durable they are. Gone are the days where you had holes within months. This top is pretty standard for durability when it comes to high-quality Merino wool base layers.
We found this to be of the most durable layers when it came to the Merino wool tops we tested. It showed only surface wear in our abrasion test which impressed us because some other, similarly weighted options now sport a hole all the way through the fabric after undergoing our abrasion test.
This is one of the few tops that states DO NOT TUMBLE DRY on the tag. Well of course we did, and we noticed signs of slight shrinkage. As always for Merino wool products, we suggest laying flat to dry. Overall a more durable option in the Merino category.
This top does a great job layering. The tight fit through the body and sleeves allow it to be layered smoothly underneath tighter fitting mid layers.
Even though it has a snug fit, the stretchiness of the fabric does a great job being comfortable when layered over a t-shirt.
This top is on the more expensive side for a crew cut base layer but to be expected with quality Merino wool. It is extremely versatile and more durable than other Merino layers tested which helps justify the cost.
Overall this top performs well in every activity and situation we threw at it. It doesn't stand out from the crowd but does its job well. With higher scores across the board, it proved itself as a good all-around base layer. A versatile weight and more durable than other Merino layers but with a poor fit for taller folks. We like it a lot but aren't madly in love.
