Arc'teryx Women's Atom LT Hoody

Rated 4.6 out of 5 by 14 reviewers.
Rated 5 out of 5 by Perfect for many activities. I love this jacket (and its very rich blue colour), it is light weight and feels like you are not wearing a jacket at all. I was torn between this and the dawn jacket (which was considerably more expensive), but the sales assistant advised that if I am not boarding in arctic temperatures and/or very high up, this should be more than enough. I wanted a jacket with a more feminine style – this one is slim fit (not super slim fit, does not hug your figure tightly, but creates a nice silhouette), light-weight and breathable (the side panels are a fantastic invention). Size is true, so if you want a jacket to layer a think jumper under – get a bigger size! No unnecessary Velcro straps. Just a great addition to your active-life wardrobe (plus suitable, of course, for leisurely strolls and casual travel). 26 August 2015
Rated 5 out of 5 by Great multi-use/multi-weather mountaineering jacket The Atom LT Hoody is a great performance jacket and a nice layering piece. It's warm, especially under a hard shell, yet breathable, and takes up hardly any space in your pack. The material at the end of the sleeves that surround the wrists is a nice feature, as you don't need to worry about velcro straps or material bunching up under your gloves. The hood is large enough to pull over your helmet while still maintaining flexibility, and the zipper releases with just a slight pull of the sides of the jacket (but doesn't fall down on its own). This past weekend I took the Atom LT to Les Diablerets in the Swiss Alps (around 3000 m), and it served me well. The temperature changed a lot from one day to the next (sunny vs. cloudy skies over a glacier makes a big difference) and it proved to be a great multi-weather jacket. The only critique I would give it would be that for the tall and slender, it feels just a bit wide, but a problem I have with all mountaineering brands. Overall a great buy. 29 June 2015
Rated 4 out of 5 by Light as a feather, and very warm This little jacket is amazing. It's so lightweight that you don't feel weighed down. The fit is close, but it has room for movement. And it is really, really warm. All without down! 29 June 2015
Rated 5 out of 5 by Great peice of kit that took my daughter up Killy and back - never was cold A great jacket- well made - expensive yes- could have bought cheaper on internet but valued the assistance in the shop to select the right jacket. My daughter gets very cold but with this garment she got to the top of Kilimanjaro in April - rainy season warm and cosy. Its packed away for the next adventure now 27 April 2015
Rated 5 out of 5 by excellent stuff It's a great outer layer during rock climbing on cool, dry, windy days. I love it! 03 June 2015
Rated 3 out of 5 by not happy with change to hood Arcteryx claim to have improved the Atom hoodie by making the hood larger to fit over a helmet and putting a drawcord to adjust the fit. I would prefer to wear the hood under a helmet to keep out the wind and therefore the previous close fitting design would be preferable. If I wore it over a helmet my ears would be cold. I have tried using the drawcord to keep hood up in windy conditions and because the elastic goes over my forehead it gave me a severe headache when pulling tight enough to keep on my head. I would have preferred the old design with a smaller hood. 05 January 2015
Rated 5 out of 5 by I love my Hoody. Slow as I am to pick up on new technologies, I didn't realise how light,compact and warm new materials are compared to my ancient fleece which I will now discard. And I can also now get a smaller rucksack for carrying it and other kit which will weigh less when out and about. 02 February 2015
Rated 4 out of 5 by I bought this jacket as a gift for my daughter. She is runs and cycles and wore this jacket almost every day after Christmas. I want one for myself. My daughter wore hers for day hikes, cycling to work or for pleasure, running and for running errands. As the jacket is new, it is hard to comment on the quality of the materials and construction. I will have to see how hers wears and preforms. 13 January 2015
