OMM Aerotherm Vest

Jump to: Our Verdict / Features / Specifications

A lightweight, windproof and fast-drying vest with added warmth for hiking and running in the mountains

Mountain Equipment says: 

With a super-light double weave soft shell fabric and a moisture-wicking micro-grid lining, this versatile windproof layer helps regulate body temperature and moisture during uphill efforts before keeping your core warm on exposed summits and ridgelines. Drying rapidly after an ascent, it’s a vest you can keep on in fast-changing conditions whether climbing, running or hiking.

The semi-elasticated hem and armholes are comfortable and help to keep out drafts, while zipped hand pockets and a chest pocket store essentials. The vest packs neatly into its hand pocket with twin carry loops for easy carrying in a pack or on a harness, making it an easy pack for days in the mountains.

Our Verdict

At 171g (medium), it’s a lightweight layer that manages to feel protective without being bulky. The EXOLITE 45 fabric strikes a nice balance: dense enough to take the sting out of a breeze, yet still breathable enough to leave on during uphill efforts. The inner grid lining is soft against the skin and does a good job managing moisture, especially under a pack. I found the fit close but unrestrictive, with clean armholes and a hem that stays in place without needing constant adjustment.

The three pockets are well-sized for stashing gloves, snacks or a phone, and the vest stuffs neatly into its own hand pocket with loops for clipping onto a harness or pack. A simple and efficient piece that earns its place on the hill.
