IO Merino

iO Merino Men's Altitude Zip Base Layer blue marle

Size

iO Merino Men's Altitude Zip base layer offers natural performance, easy layering and a whole lot of comfort that can be used as a base/first layer or on its own. With the 3/4 zip up or down, it’s perfect for anyone who’s on the go, especially if you’re expecting to hit a range of temperatures while you’re at it. The high collar, when zipped up offers an extra level of warmth beyond the crew neck version of this top.   

Made with iO Merino's flagship Enigma MicroMerino® fabric – 96% superfine Australian Merino and 4% Elastane for durability and four way stretch for freedom of movement when you’re on the go as well as incredibly soft next to skin feel.

With flat lock seams, heat transferred tags and raglan sleeves to help prevent chafing, plus thumb loops and a drop back hem for easy layering, the Altitude Zip is the perfect combination of performance, warmth and comfort.

Designed to be worn as a snug ‘contact fit’ layer, we’d recommend going up a size if you’re looking for a more casual fit.

Tight underarms. Returned for looser fitting garment.

Great chamois

Great chamois!
I usually choose XS or XXS but for this shorts S fit me well (it is a bit tight when I squeeze my hips in).

Best bib shorts ever

Great transaction

Another flawless product from Assos

I purchased this to replace a previous generation Assos Mille jersey. The fit and fabric are excellent. The fit is more aero than the previous generation, but they've managed to maintain comfort due to the bespoke fabrics they create. It's a Super Nice from me.
