  1. Can You Wear Two Base Layers?

    Comments Off on Can You Wear Two Base Layers?

    Can you wear two base layers? - Sub Zero Factor 1 and All Active worn by a female hiker

    At first glance of the question, Can you wear two base layers? You immediately think yes you can but why would you want to? Most outdoors people are well versed in the principles of the layering system – base layer, insulating mid layer, protective outer layer – so why would you ignore this and just wear two base layers. The problem is that in certain situations this layering system can be impractical.

    BASE LAYERS FOR AEROBIC EXERCISE

    If you are going to take part in a high intensity aerobic exercise in winter such as rowing, it is unfeasible to wear lots of different clothing layers. For a start you are going to get warm very quickly as well as producing a lot of perspiration.  You are also going to need full range of movement which will be hampered with a traditional layering system. Plus there is also the problem of storing all these different clothes when removed.

    What a lot of professional rowing teams practice in winter is wearing two thermal base layers at the start of a days training programme. Without being restrictive, these thermal layers will keep you warm whilst also managing perspiration more efficiently. Once the warm up is complete, one of the base layers is removed and easily stored in the bottom of the boat. At the cool down, the discarded base layer can be worn again to reduce rapid cooling.

    Even in the coolness of early summer mornings a two layer base layer system is often used. Next to the skin will be worn a summer base layer to manage perspiration, with a thermal base layer as a second layer to provide extra warmth during the warm up.

    BASE LAYERS FOR SPRING AND AUTUMN WEATHER

    Out of the winter season, the need for a full thermal layering system is usually unnecessary. With the temperatures very rarely reaching freezing, you should be able to get away with just wearing your base layer. However, some early mornings and evenings may see temperatures drop low enough to require wearing extra layers for a boost in warmth. You could pack a thermal mid layer on the off chance, but it is a lot of unnecessary weight to carry.

    Instead, ensure you are carrying a second base layer – you should be carrying a spare set anyway if you are heading away from civilisation. They can easily be worn over your first base layer and are light enough to be stored in a small rucksack.

    BASE LAYERS FOR EXTREME COLD ENVIRONMENTS

    When it comes to very cold weather, such as found in the polar regions or the Himalayas, mountaineers and explorers will often wear more than one base layer as part of their layering system. The main reason for this is you can trap more air between thin layers than wearing bulky insulating layers. And trapping air is essential if you want to keep warm because air is the insulator, not the fabric.  It is not uncommon for mountaineers to wear two or even three base layers beneath their insulating mid layer.

    SO CAN YOU WEAR TWO BASE LAYERS?

    Instead of being a bit of a wacky question there are certain situations where wearing two base layers can actually be desirable. It is a lightweight alternative to heavier insulating mid layers and also offers greater flexibility in less demanding weather conditions. So the question shouldn’t be can you wear two base layers? but have you tried wearing two base layers?

  3. Clothing Layers For Keeping Warm When Winter Walking

    Leave a Comment

    In a few weeks’ time, the clocks go back, temperatures start to fall, days get shorter and walkers need to take even more care in the hills. Clear blue skies can change rapidly and windchill can sap energy and will. It’s not only those tackling airy mountain summits and ridges who need to be thinking hard about what to wear and what to pack in a rucksack as winter wraps around us but also walkers choosing less exposed routes. It’s always tempting to wrap up warmly and head off smartly but, if you’re not careful, it won’t be long before you’re hot, sweaty and uncomfortable.

    The key to comfort is layers of clothing – a baselayer to shift moisture away from your skin where it would chill as it cools; a mid layer for insulating warmth and an outer layer that will offer protection from wind, rain and snow. As a cold wind can whisk away body heat carrying an extra warm layer makes sense as does a cosy hat and gloves. Avoid overheating by sticking to a comfortable pace and letting heat escape by quick simple ventilation options such as opening zips and cuffs and whipping off your hat.

     

  4. Sub Zero Lightweight Thermal Down Jacket Wins Top Review

    Leave a Comment

    “Three hundred grammes. That’s the weight of my wallet and iPhone combined. The two things, along with my keys, that I carry everywhere, regardless of outfit, weather and circumstance. I don’t even feel them any more, such is their familiarity in my pockets, and it’s not like they weigh an awful lot.

    In fact, they weight exactly the same as the Sub Zero Thermal Down Jacket, which considering its size, must surely be filled with helium. It’s extraordinarily lightweight, and yet with a fill power of 800+ goose down it is extraordinarily warm too.

    Snuggly like a sleeping bag 

    I went for a walk this morning in a T-shirt and this jacket. The temperature is 7C and I was, at times, so warm in the jacket that I needed to take it off. It’s like a sleeping bag, trapping huge amounts of air inside its 3-4cm thick down chambers and closely-fitting the body to seal in all your body warmth. It doesn’t make sense that something so light could be so warm – the mind naturally equates weight with insulation – and yet it is.

    The external shell material is a 100% Polyamide and extremely thin. It feels like it would rip at the merest snag, but having worn it through a few woodlands it is much tougher than it looks. The only change to this material is the addition of a warm fleece material on the neck, which doesn’t rub or get sweaty and helps trap air from escaping upwards.

    The main zipper is a chunky YKK number with an effective chin guard and nice positive action. It has a wind-baffle behind it to seal out the breezes. The cuffs are elasticated, and the waist has a bungee drawstring to keep the wind from chilling you. You get two zippered hand pockets which are perfect for doubling the weight of things with your phone and wallet!

    It’s not sold as waterproof, but it has survived a couple of short-sharp showers admirably, which was a pleasant surprise. I suspect that this is due to the extremely dense nature of the shell fibre, rather than any treatment.

    The jacket lacks a hood, which keeps the weight down but means you’ll need to match it with a hat on the chilliest days. Sub Zero make a range of good hats, so that’s no bother.

    And lastly, as a hint on how the jacket could be used, Sub Zero supply it with a small drawstring bag so it can be stuffed down and carried in a pack until it’s needed when the weather gets cold.”

    • Stay on the path and away from cliff edges
    • Take extra care in windy and/or wet conditions
    • Always supervise children and dogs
    • Leave gates and property as you find them
    • Remember that mobile signal can be patchy in some coastal destinations so let

    • Protect plants and animals, and take your litter home

  6. Thermal Underwear for the Snow

    Leave a Comment

    With sub zero temperatures and snow enveloping the country a good set of thermal underwear is a necessity to keep you warm and dry if venturing outside. Sub Zero manufacture performance warm clothing in a range of weights and styles to allow you to work rest and play in the coldest of conditions.

    Factor 1 Thermal Underwear Base Layer

    Factor 1 garments by Sub Zero are one of the most technical range of base layers available. They are manufactured from a lightweight rib 100% Polyamide fabric designed to be worn next to the body. Each fibre is impregnated with a hydrophilic finish that transports moisture away from the skin and disperses it over a large area of the outer layer of the fabric so it can easily evaporate. This provides a warm dry micro-climate next to the skin that gives you greater performance and activity longevity. An ideal thermal base layer system for cycling, walking & hiking, skiing, running, golf and climbing.

    Factor 1 Plus Thermal Underwear Base Layer

    Factor 1 Plus thermal base layers by Sub Zero are manufactured using the latest seamless technology. Instead of the traditional cut and sew technique for adding features, the machines we employ can knit in the desired attributes without seams. This eliminates rub points and possible stitch weakness in the garment. The Factor 1 Plus range of base layers are produced from lightweight 100% Polyamide yarn, that produces a super soft fabric that is easy to care for and long lasting. In addition, each fibre is impregnated with a hydrophilic finish that transports moisture away from the skin and disperses it over a large area of the outer layer of the fabric so it can easily evaporate. This provides a warm dry micro-climate next to the skin that gives you greater performance and activity longevity. An ideal thermal base layer system for cycling, walking & hiking, skiing, running, golf and climbing.

    Factor 2 Thermal Underwear Mid Layer

    Factor 2 heavyweight thermal mid layer range has been uniquely developed by Sub Zero over the past 15 years. We have specially developed and manufactured our double sided Factor 2 fabric with a harder wearing anti-pill outer surface and a super soft brushed fleece inner. Factor 2 thermal underwear mid layers can be worn on their own or on top of our Factor 1 thermal underwear base layers when the temperature plummets.

    The two main functions of Factor 2 garments is to transport perspiration away from your skin, or the surface of Factor 1 base layer garments, to its outer surface to disperse. At the same time the inner brushed fleece surface traps warm air to insulate the body keeping it dry, cosy and a comfortable even temperature. Each fibre is impregnated with a hydrophilic finish that transports moisture away from the skin and disperses it over a large area of the outer layer of the fabric so it can easily evaporate.

    A further advantage of the fabric is that it does not compress under pressure. This is essential if it is being worn under a dry suit as your insulating layer stays the same thickness no matter how deep you dive.

    The Factor 2 thermal mid layer range is regarded as one of the warmest undergarments available on the market today.
