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.

Santini thermal Bordeaux jersey

Great top nice fleece for Sydney winter go up a size if wondering

Halo Anti Freeze Headband

Great purchase for warm ears in the freezing cold.

Cycling jacket

Great jacket for the rain and lightweight so that one can keep it in back of top when rain stops

Good winter jersey

I brought one of these jerseys, coupled with the BBB Coldshield bib tights last year prior to moving to Canberra. Yeap, negative temperatures and they have performed excellently. The fit is comfortable and I've found the warmth factor to be satisfactory a little on the chill side but not uncomfortable. Slightly chill is good 'cause a few of my morning rides into work (26km) have meant leaving home when it's -6 degrees and not much warmer at the destination and you quickly warm up on the hills. This jersey has had a good workout this year and I'm planning on getting a second, just hanging out hoping they'll come on sale soon though I will say the price is pretty good value even at full price.
