Rachel Keenan Tests the Helly Hansen Warm Freeze Baselayer Top

With spring adventures just around the corner, but a chill still hanging in the air, we're looking at this season's versatile baselayer choice for professional skiers from Norwegian brand, Helly Hansen.

The Overview

Helly Hansen have been pioneers of the outdoor clothing market since their establishment in 1877, and were the first brand to introduce many ground breaking technical garments now regarded as commonplace, including fleeces in the 1960’s and technical base layers in the 1970’s. I absolutely love this women’s warm freeze base layer, and it is now my firm favourite for any adventure! Thanks to specific design featured to ensure a comfortable fit and outstanding levels of insulation, the warm freeze baselayer top is a great option for your adventures from Munro bagging to hitting the alps on a pair of skis.

This base layer has joined me on numerous outdoor pursuits in recent months, ranging from the incredible Munro ridge traverse of Buachaille Etive Beag in Glencoe and cliff top walk along the National Nature Reserve St Abbs head, to a 10-mile circumnavigation of the beautiful Island of Cumbrae on a tandem bike. In every environment, the baselayer has performed well with excellent warmth and comfort no matter what I wear it with. Most people think that merino wool will be itchy, but this feels like any other high performance technical base layer and it feels great!

The Features

Before I give you my verdict, let’s have a look at the features that make this such a versatile and comfortable product for cooler weather adventures. Firstly, this base layer features the innovative Lifa ® Stay Dry Technology. The fabric used in the Warm Freeze Base Layer is made with Lifa ® Stay Dry Technology - which absorbs 40% less moisture than its leading polyester competitors - combined with a layer of merino wool, meaning that it transfers moisture away from the skin, whilst simultaneously insulating against the cold. This can be really important due to Scotland's quickly changing conditions, and helps when thinking about how to layer up for those spring adventures! I could easily feel the benefit of this key feature at the summit of my second Munro of the day on Buachaille Etive Beag, feeling comfortable enough to stop and get the all-important cairn summit photograph taken without the immediate need to wrap up against wind chill.

Being able to pause, catch your breath and take in the views of Loch Etive and the Glen Coe valley is what hiking is all about for me, and feeling warm and comfortable is one of the most integral factors which influence that enjoyment of a day in the hills. This product really goes the extra mile in that department. As well as being breathable with fantastic moisture management and temperature control, the half-zip feature adds a further element of adjustable ventilation when required. This makes it the best choice for anyone looking to add a new base layer to their outdoor kit.

When doing high-energy activities, too much sweat can make you cold and uncomfortable. Lifa Stay Dry Technology is based on a fibre that is constructed in a completely different way than most other synthetic base layers on the market. When exposed to moisture, the Lifa fibres immediately move it away from you skin, allowing the moisture to evaporate into the air or into the next layer, keeping you dry and comfortable.

The Verdict

I would honestly 100% recommend this items to anyone. It's a brilliantly versatile piece that is great for all four seasons. As you can see from my photographs this garment is now fairly well-travelled; I wear it everywhere, and it is also my go-to for regular daily activities such as jogging through the park! The anti-allergy properties, flat lock seams and fantastic Lifa Stay Dry Technology make for such a comfortable, second-skin-esque base layer, that I no longer need to worry about feeling the cold, or being comfortable in my base layer! The warm freeze base layer is completely perfect for Scotland’s pretty consistently chilly climate, this top makes an excellent addition to the kit of anyone who likes getting out there and exploring.
