Fast and Light. They are buzzwords in the world of trail, mountain and ultra running. We could argue all day about how this came about. Many would potentially give Kilian Jornet credit for the movement but I think it’s fair to say that men and women have been going light to the mountains and trails for quite some time, it’s just recently that we have all become far more aware.
Light does have its problems!
We have many documented reports, articles and stories of runners, mountaineers or alpinists being ‘caught out’ on a mountain and as a consequence in certain circles, mountain runners have gained a bad reputation.
Travelling light is all well and good providing that you are able to move fast! The two words go together; FAST and LIGHT! But what do I mean? Well quite simply, the process of going light will almost certainly mean that what you carry as a runner or alpinist will be minimal. Minimal of course is subjective and dependent on the person. For arguments sake, lets call light as follows:
- Waterproof Jacket
- Pack to carry water
- Mobile phone
In essence, that is going light to the trail or mountain. Should conditions become difficult or problematic, this is where FAST comes in. You need to get out of trouble, danger or the cold fast and to safety. In many respects, this is part of the challenge. Running in the mountains is not a risk adverse sport.
What if though you could add a 1000 fill down product to your pack for a weight addition of 3oz (85g) or 6oz (180g)?
I kid you not.
UK based company PHD currently have 2 remarkable products that embrace low weight, low pack size and ultimate functionality in a limited availability range of products called Summer Lightning.
A SUMMERLITE DOWN JACKET (£199 6oz) and a WAFERLITE DOWN VEST (£99 3oz) are part of the K Series range of products that offer ultimate warmth against minimal weight. Filled with 1000 fill power European goose down (responsibly sourced) the jacket has a water-resistant Ultrashell outer fabric, stitch through construction and the vest has a 10x inside and out fabric that is not water-resistant and stitch through construction.
I have to say, having tested both these products I think PHD should make them available all year around. As a brand, my understanding is that they see them as a warm alternative for summer months but to be honest, they are a great addition to any kit list irrespective of the time of year. Both products would provide ideal warm layers to any multi-day adventure such as MDS. The potential to combine a warm layer and lightweight sleeping bag are endless. The apparel would also make a perfect addition (for every run) to any mountain runner’s kit list and lets face it, for fast packing they are brilliant. You see, these products are so light, so small I simply can’t think of a reason not to take them! I even have the jacket packed away in my day-to-day laptop bag or camera bag for that ‘just-in-case’ scenario.
I have had both products for 1 month and I have tested them ‘in situ’ at Richtersveld Wildrun in South Africa and at the Ultra Skymarathon Madeira. Both races provided me with changeable weather and an opportunity to test each product to the full.
On first impressions it’s difficult to believe that when one looks at these items compressed in a small stuff sack that they could possibly be a down vest and a down jacket. You pick up the vest and you don’t even notice any weight. It is just 3oz. The outer Ultrashell fabric on both products is silky smooth and a pleasure to wear against the skin. I wore the vest and jacket with just a t-shirt underneath and found them both really comfortable.
They may be light but they are warm, really warm. Let’s be realistic, they are not for polar conditions. But if you need a warm layer to protect against morning or evening chill, daily colder or cooler temperatures or an additional warmth layer to be added under a Gore-Tex (or similar) or windproof jacket, they are the perfect choice.
They are arguably the lightest down products in the world? Both pack to the size of an apple!
I have to say, I was spoilt; having a vest and jacket did allow me to regulate my temperature extremely well and on one occasion I actually wore the vest under the jacket on a very cold and damp night in South Africa.
They are simple, no frills products. The vest has no pockets and just a half-zip to reduce weight. The jacket has a full-length zip, two side pockets and a short stand up collar with no hood. However, it is possible to add a hood when ordering for the additional cost of £27.
As with all PHD products, items are made to order and this does allow you to customize any apparel exactly to your needs. For example, you could have a jacket with a half-zip, no pockets and a hood! The choice is yours.
Please keep in mind that if you need or require products by a certain date, you will need to allow for manufacturing time.
On the go, I found adding or removing either the vest or the jacket easy. They pack so small that I could actually just stuff either item in the pocket on my shorts. This is important because as soon as you start to move quickly, they retain heat exceptionally well and you find that you need to remove them so that you don’t sweat. Of course, as soon as you stop, you can quickly access the vest or jacket and wear them so that you don’t get cold
I wore the jacket all day on a very wet and chilly South African day and the Ultrashell outer fabric did a great job protecting the down from wet and moisture. Admittedly, I did wear a waterproof layer over the top. But in and around base-camp I was often moving from one tent to another with no waterproof layer and the product held up well with no problems despite constant drizzle and rain. Notably, the vest and the jacket did a great job of blocking out the wind.
PHD has come up with two incredibly light and small items of apparel that are now part of my ‘essential’ kit. They are so small, light and effective that I can’t be without them. Yes, they are that good!
Do I have a negative comment?
Down does not like rain, wet or moisture and it effectively becomes useless should this happen. Ultrashell fabric does protect the insulation in the jacket but this would only protect to a certain extent. So, if you anticipate bad (wet) weather you would almost certainly need a Gore-Tex or similar 100% outer layer to maximize the 1000 down fill. To be honest though, if you were going to the mountains a waterproof outer layer should be mandatory no matter how light you are going!
On a final note, I can’t recommend these two products enough. They may not be the cheapest apparel available but what you get are two incredible products that are functional, pack small and are superlight. Did I also mention that PHD has two sleeping bags that are also part of this range: ELITE RACER DOWN BAG (8oz) and RACER DOWN SLEEPING BAG (90z) more news on those to follow.
