Marmot ROM (2014)

ROM stands for ‘Range Of Movement’, and this selling point is achieved by an all-over two-way stretch fabric with four-way stretch breathable panels under and along the arms. The Marmot ROM is also a generously long jacket that isn’t prone to riding up. Both of these assets notwithstanding, the freedom of movement isn’t massively more striking than other jackets in this test, but the ROM has plenty more besides to recommend it. The outer is of top-quality Gore Windstopper and while the DWR (durable water repellent) isn’t as impressive as some here, breathability is good and the jacket is surprisingly warm for something so slight-feeling, making this a true season-spanner. Two extraordinary handwarmer pockets that cover the full length of the trunk – shoulder to hem – make the fact that the pockets fall below a rucksack hipbelt easy to forgive. It’s difficult to think of an application for them but it’s good to have the option! The wicking backer on the fabric keeps condensation moving while stopping the wind from entering, making the Marmot ROM particularly suited to walking in changeable conditions. In place of pit zips you get breathable stretch panels under the arms, which – if not quite as effective – help keep the weight down. The Marmot ROM can feel and look a little baggy, but it is immensely comfortable in a broad range of temperatures, and the overall quality is great.
