Olive Yellow, But Uglier
Another reviewer commented on the color and I thought, “It can’t be that bad.” Well, they underplayed it. While Lux looks like a delightful golden yellow in the picture, it is truly a hideous shade of yellow olive. It did fit and feel nice, but I am returning it.
A chic top for sunny days!
I absolutely adore the fit of this shirt, the Passion color is so vibrant in person! If you have a longer torso, I would recommend sizing up. I have a shorter torso, and the size S fits like a glove. This shirt is going to be a staple for me this spring and summer. I'm excited to take it biking, hiking, trail running, and wear it as a stylish piece. The Passion color added a fun pop to my wardrobe. Merino and Tencel fabric have truly won my trust in warm weather!!
Not durable. Develops holes quickly
The Sphere line of IB develops holes fairly quickly despite your loving care. This line is just not durable. Cool, comfortable, soft, yes. But I need durable and this is not it. I’ve tried two, never again.
Perfect light merino tshirt
I love this shirt I wear this almost every adventure. It is very light but is perfect for California heat. I’m an icebreaker stan. I think it does run a bit small if you like a roomier fit.

Great for Travel and Workouts
A few years ago, I bought this tee in grey for workouts but it turned out to be my favourite for travel. I like how it flows around my body, and the fabric isn't itchy. Liked it so much, I just bought the tee-shirt in blue. It's gonna be another favourite.
*very* see-through, different neckline, versus 2023 version
I love my 2023 Sphere II Cool-lite t-shirts in light blue, but this one is way too see-through! Even indoors in normal light, the outline of my belly button, my sports bra (which matches my skin color) and straps, and the top of my shorts all show through clearly. Don't want to imagine a photo from a sunny day outside. They also made the neckline less flattering and versatile (IMO) by eliminating the slight scoop of last year's. Returning this one and keeping it in black (despite the neckline) though I really wanted a happier color and the slight scoop neck.
Not quite
Bought 2 of these in different colors. Review is only for initial fit/size as I returned both. Pros: like the material, is soft yet textured, would layer under long sleeve well because smooth; feels like it would breathe well with part merino, part Tencel. Cons: The crew neck is too high and too small for my comfort and aesthetics; I have wide shoulders and average size and strong neck so the high neckline makes me look stocky. Cannot speak to durability. Bummed these didn't have a wider scoop or v-neck.
Older Traveler
Love this top since I will be using it to pack light on a trip to europe. I love the feeling next to my skin.
Useful in any case
Very comfy in warm and cold weather, useful as base or top layer, stink resistant.
WEIRD SIZING WITH TOP HALF TOO SMALL
I consistently wear Icebreaker size small and the second T I bought along with this one fits perfectly. But this T (with its gorgeous color and fabric) has an inconsistent fit: it is too small from the waist up. The neck is very snug, the shoulders too narrow, and the bust pulls taut across my modest 34B bustline. Below the waist the fit is perfectly loose and comfortable. Darn it! I so love the color but will sadly be returning.
