Berghaus says:
Designed to be used as a layering piece for the entirety of aerobic, start-to-stop alpine pursuits, helping you to maintain the perfect temperature. Wearing the windproof outer to keep chilly breezes off your core body, or reversing to wear that fabric next to your baselayer and have a more permeable outer that enhances breathability. Versatile warmth without bulk, or unnecessary weight. The Mtn Arete LB Synthetic vest is fitted within an inch of its life to ensure maximum movement, meaning you won’t even notice you’re wearing it, making this a year-round favourite
Our Verdict
The main thing that stands out about the Arete LB is that it is reversible, offering two jackets in one, meaning that the range of uses is more prominent than your typical synthetic. One side is a windproof layer that offers protection from the chill while moving and keeps you insulated. The other side has a more breathable fabric that allows the wind to pass through, cooling you down when your work rate is higher and you need loose heat.
This dual function means that it is the perfect vest for several uses and allows you to switch between these uses; the insulated side is perfect for use on the bike, a quick trip outside on a cooler day, or as a lightweight mid-layer. The breathable side is suitable for moving fast on a winter trail run or a fast ascent.
Unfortunately, this could do with an integrated stuff sack, but I managed to pack it into its pocket and zip it up quickly, and it has a tiny pack size so that it would take up very little room in any rucksack.
The fit is looser, so if you usually size, there is space to get a fleece underneath, but if you want a closer fit, I suggest a size down.
The Arete LB has various uses, and given its weight, it would be perfect to always keep in your bag no matter the season or activity; it is undoubtedly a step forward in synthetic vests.
