Montane Protium Lite Pull On review: fleece meets base layer for lightweight warmth

Montane Protium Lite Pull On

Montane Protium Lite Pull On: first impressions 

In this top, Montane have merged all the best qualities of a fleece with a base layer. It has the exceptional warmth and softness you expect from a fleece when worn on a cold hike, but the super light weight and active fit mean that you can easily wear it for fast adventures. It’s breathable when you’re moving fast and super stretchy for scrambling and rock climbing

Specifications

• List price: $99 / £65
Gender specification: Men’s and women’s available
Sizes: Men’s XS - XXXL / Women’s XS - XL
• Weight: 170g/ 5.9oz (women’s small)
• Materials: 92% Polyester, 8% Elastane
• Colors: Black, alder green, acer red, slate, allium, eclipse blue, Saffron red

The outside of this high-neck, half zip top appears like a smooth synthetic base layer, but on the inside you’ll find brushed grid fleece which is warm, soft and moisture-wicking. This also means your favorite top doesn’t end up with annoying pilling where your backpack straps rub. Flatlock seams mean you can happily wear this with nothing underneath, but it has a snug enough fit to layer a jacket on top. It lacks thumb holes, if you like those for added warmth, but other than that we really can’t find anything to complain about.

Montane calls this a fleece, which to me conjures up a substantially bulkier, cozier mid layer, so I was surprised to receive this and discover it’s really a base layer, in my opinion, made using fleece. I’ve been wearing it on some chilly spring hikes in Scotland over the last month and really like the innovative approach. The only hair I can find to split is that it doesn't have thumb holes, which isn't really a problem for me anyway.

Here’s how it performed:

Sizing and fit

This fits true-to-size (I tested a small, as usual) and has a slim, but not skin tight fit, which is why I’m classifying it as a base layer. I easily could wear a tank top underneath it on a warm summer day, though I haven’t yet. All this means I can wear it on its own when it’s mild and layer over it when it’s cold.

Comfort

This base layer has a barely there feel, which I really enjoy. Basically, each time I’ve worn it, I haven’t noticed I’m wearing it, which is just what I want. The brushed fleece is soft against my skin and there’s no rubbing. 

Temperature regulation and breathability 

I’ve worn this on a few quite cold days and been glad for the extra warmth the fleece provides. That said, the breathability has proven to be quite good for milder days, too. 

Weight and packability

It’s as light as any base layer I own, though doesn’t roll up quite as small as my typical merino wool layers because, being fleece, it is a little thicker (you just don’t notice because it’s so light). 

Odor control and durability 

Like all synthetic fabrics, the armpits do get a bit smelly but only after a couple of hikes, which feels like progress. No signs of wear and tear after a couple of washes and wearing it with my backpack.
