The REI Space Dye Zip-T was one of the base layers that we continually reached for on a daily basis! Our testers loved its long torso and sleeve length, as well as its features, all of which made it a go-to for around-town wear and quick ski missions.. This synthetic top has the right amount of stretch and doesn't fit too tightly where it matters. That's right ladies - if you have big boobs, this top will most likely fit you! Like the Arc'teryx Rho LT Zip - Women's it has a zip collar, but it doesn't have the same level of warmth. If you're in the market for a very breathable wear alone piece, this is a great option. However, avoid it for abrasive or really cold activities as its warmth and durability is limited.
The Space Dye Zip-T has been discontinued, but you can peruse our complete Women's Long Underwear Review for other options!
