Icebreaker 260 Quantum Long Zip Jacket

The last thing you need when you are exploring the great outdoor is restrictive or cumbersome clothing, layers however are an absolute must. The Icebreaker 260 Quantum Long Sleeve Zip Jacket is a mid-layer that aim to quietly gets on with the job without demanding attention. It won’t promise to get you to the top of the mountains twice as fast, but when the temperature drops, you’ll be very glad of its companionship.

Made from 100% merino wool, a wonderfully soft, lightweight and naturally wicking. Merino’s ability to regulate body temperature is well known, helping keep you warm in cold conditions without feeling stuffy when you’re working harder. Better still, it naturally resists odours, meaning you can wear it for several days on a hiking trip without frightening away your walking companions.

The slim, athletic fit makes it ideal as either an outer layer on cool autumn mornings or beneath a waterproof shell in harsher weather. The offset shoulder and side seams minimise chafing during long walks, while the sleeve cuffs feature thumb loops to keep the sleeves in place whether you’re scrambling over rocks or simply reaching for another biscuit. The full-length front zip allows for quick ventilation, and there are zipper hand pockets that provide somewhere to warm cold fingers or stash small essentials. Icebreaker also includes a hidden zipped chest pocket for valuables.

Despite weighing only around 430g for a men’s medium, the Quantum feels reassuringly substantial thanks to the dense merino knit, yet light on the body. The dipped hem adds extra coverage and the underarm panel gives you extra mobility without revealing any bare skin to the elements.

Its biggest drawback is durability compared with some synthetic alternatives. Pure merino requires a little more care when washing and can be more susceptible to abrasion if regularly worn beneath heavy rucksacks. It also sits firmly in the premium price bracket, although the comfort and versatility help justify the investment.

For hikers, travellers and anyone who spends time outdoors once the weather turns chilly, the Icebreaker 260 Quantum is an excellent mid layer. Comfortable, stylish and remarkably adaptable, it’s a layer you’ll reach for far more often than you might expect. RRP £175
