Altitude Zip and Crew - Mix and Match Bundle

Our Altitude range was originally designed as a baselayer, to fit close to your body for maximum performance, so it’s snug but soft, with plenty of give for extra comfort. If you’re usually a medium, for example, you might find the medium fits tighter than you’d expect because it’s designed to be ‘contact fit’ and look and feel like a second skin. If you’re looking for a more relaxed fit you might consider sizing up (it will still be relatively snug) or choosing another style.

The Women's Altitude Crew Neck and Zip Base Layer are our ‘go to’ thermal layer tops for just about any adventure. These are the perfect thermal layer options for core warmth when you’re layering up, yet versatile enough to be worn on they're own in milder conditions.

Tag-free, flatlock stitching and raglan sleeves help eliminate chafe and maximise comfort. The drop back hem and extra body length is designed for tucking into your outer layers. Thumb loops keep your hands warm and stop your sleeves riding up when layering. And the zip top has a high collar that offers an extra level of warmth when needed. 

This top is the perfect combination of performance, warmth and comfort.

(For a more relaxed fit try our Ultra or Universal tops.)

SIZE & FIT

Originally designed to be worn as a base layer, (is usually underneath something else), this is a ‘contact fit’ layer so will hug your body. If you don’t want it to fit, feel or look like a second skin, you might try another style, or go up a size, but please note: even going up a size will fit quite close to your body because of the fabric and cut.

Stunning Altitude Zip & Crew Set

After much research on merino base layers, I ended up choosing this set from IO Merino and truly glad I did. These tops look to be high quality & are ethically made and I think they'll be perfect for keeping me warm & comfortable for my upcoming Canadian snow skiing trip. I love merino and the many features of these great tops - they are lightweight yet provide good warmth, are moisture wicking & breathable so any sweating won't chill me, and the seams lay flat and no annoying itchy tag, and the raglan sleeve is made for comfort too. And you can't beat the natural odor resistance of merino (great so I can get more wears out of them & pack less). The tiny bit of elastane in the fabric works brilliantly to keep thede base layers skin tight and stretchy enough to gently hug my curves. I was initially only going to buy 1 Altitude long sleeve top but pleased to have the versatility of 2 tops to allow for rotation & styling with the bonus of extra temperature regulation with the zipped one. I found the Customer Support Team Member I dealt with to be outstanding and so helpful & knowledgeable responding to my questions, which resulted in the correct size and that all important 'contact fit' being chosen; not too tight nor too loose. I did need to exchange the charcoal marle zip neck for another zip in a different colour because that heathered fabric for a base layer was a little too prickly for me, so something to be aware of if your skin is overly sensitive like mine. The replacement zip I received in Morrocan Blue is lovely and there's minimal prickle with this one so I should be able to wear either of my 2 tops for hours of skiing (& whatever other outdoor pursuits) with no issues. So thanks to this company & their terrific team for their thoughtfully designed & beautifully manufactured merino garments and making this a positive online purchasing experience for me.
