- If you're into lightweight hawking
- you are going to love the Spark sleeping bag
- from Sea to Summit.
- I'll go through them in front of me here,
- but there's a total of five in the range and I've
- got a lot of information to get through,
- so let's get started.
- Hit it.
(Upbeat music)
- There you can see in folks, in front of me I've got
- The Spark sleeping bags from Sea to Summit.
- These are the ultimate lightweight bag,
- for the lightweight adventurer.
- From summer adventures through to winter adventures.
- There's five in the series starting with the SP0,
- then there's the one, two, three and the four.
- Which one you choose depends on how warm you
- want it to be.
- The lightweight one which is this guy here,
- also doubles as a liner, its got a comfort rating
- of about 14 degrees.
- Right through to the warmest bag, which is
- the SP4 one the bottom here.
- Comfort rating of minus eight and a lower limit
- of minus 15 degrees.
- And if you're talking about weight, the lightest one
- here once again, just 225 grammes.
- And the heaviest one, still under a kilogramme,
- at 985 grammes.
- And when you buy a bag,
- they come in a storage sack like this.
- There's two different sizes.
- The smaller one, the zero, one and the two come
- in a small storage sack like this.
- Whereas the three and the four come in a
- Storage sack like this.
- And inside you'll also get a stuff sack, and in the
- case once again of the smaller ones, the SP1,
- this tiny little stuff sac here.
- You get your down certificate , which is gonna tell
- you, the actual loft of the down that's
- inside your bag.
- Usually it rates to much higher
- Then the advertised level of the down.
- And in the bigger bags, you actually get
- Compression sac, so you can stuff it in and
- squash it all down, so that's actually got
- compression straps on the side.
- In terms of the sizes that the bags come in,
- Being five in the series, they're all a
- little bit different, so bear with me while
- I try and explain it.
- I'll start with the SP0, the one which I don't have here,
- and the SP2, now these all share the same dimensions.
- All available in regular and long lengths, with regular
- being suitable for up to 183 centimetres, and the
- long up to 198 centimetres.
- Now the long version of each also offers a
- little bit of extra width than the regular.
- Then you've got the SP3, which I don't have in the SP4,
- which is this guy here, they share the same
- dimensions as well.
- Also available in regular and long,
- for 183 and 198 centimetre uses.
- But these are expedition sizing, so they actually offer
- extra width again over the top of these bags, to allow
- for a bit of extra clothing to be worn inside the bag.
- this will give the fabric sit to some have used
- in the spark series here.
- These are made with weight in mind.
- They're made to be to be ultra lightweight.
- So this exterior here is a 10 denier nylon.
- Underneath here, 850 loft, ultra dry, goose down.
- That's gonna, the ultra dry is a nano treatment,
- this all but eliminated the affects that moisture
- has had on down in the past.
- And the lining inside here, is a really lightweight,
- 7 denier nylon, that's got a nice soft to
- Silky touch to it.
- Now while we're inside the bags, I want to talk about
- the features that you've got in there with regards
- to draught, tubes in the likes.
- Now they're all a little bit different being
- five in the range.
- Starting with the SP0 and the SP1, now these guys
- Don't have a draught tube down the side,
- they don't have a neck muff.
- The SP1 does have a bigger hood or does have a hood
- where the SP0 doesn't.
- But they're made to be fairly simple lightweight bags.
- Once you get up to the SP2, you start to get
- a few extra features say.
- Inside this bag here, you have got a lightweight
- anti-snag feature along the zip here.
- You do get a draught tube along the zipper as well.
- You don't have a neck muff at the back of the neck here,
- but there is an oversized collar around the hood here
- to stop a bit of draught.
- And then when you get up to the SP3 and the SP4,
- You get all the features say.
- Inside this guys here, you get your anti-snag
- Along the side of the zip here.
- You get your draught tube that runs right along the zip,
- which goes right to the foot.
- Now the SP4 has got a rear neck muff,
- that's not on the SP3 though.
- But you do get on both models a large collar
- that runs around the back and the top of the hood here.
- Some features inside, there's still a lot more
- to go through.
- I want to talk to you about then
- general construction of each one.
- Lets start with the SP0, now trying to explain
- the differences in construction with these bags.
- First thing want to explain the difference box and
- Sound through construction.
- Sound through means the outer layer of the bag
- and the inner layer of the bag, actually pinch together
- at certain points to create pockets of down, like this.
- So where this stitch is, is the same stitch
- on the inside.
- Whereas box construction, doesn't allow that to happen.
- This inner layer here and this outer layer here ,
- actually has a little baffle in between.
- So the outer layer and the inner layer
- never actually meet.
- That's a much more efficient way of making the bag,
- Because there's no cold spots, where the fabric
- pinches together.
- Now that you know that.
- Let's talk about the construction of the spark bags.
- Now these guys, are a complete sewn through construction.
- They've got a quarter and a half zip,
- with a single slider.
- There's no hood on the SP0 and a three dimensional
- box foot section.
- The SP1, is the same construction as the SP2,
- Which is this guy here, it has a vertical baffles here,
- and horizontal baffles here.
- And the SP1 also completely a sound through construction.
- Its got a hood with a half zip and a single slider.
- Now the SP2 is this guy here, has a combination
- of box and sound through construction.
- Box construction at the top, with the vertical baffles.
- Sound through at the bottom, it's got a hood and
- its got a half zip or a quarter zip.
- Well it's a half zip on this one actually,
- with two sliders so you can ventilate from the bottom up.
- Now moving up to the expedition series.
- These guys have got all the features and they are
- Completely box construction throughout.
- With a full length side zipper, no foot zipper,
- but a full length side zipper, with dual zips
- on each end.
- The box foot construction and the hood on the top there.
- I hope that made sense, there's differences between
- each bag, tried to explain it as best I can.
- One thing I haven't mentioned though,
- is these aren't actually zip coupling compatible,
- So you can't join one bag to another.
- What I want to do though is crawl inside
- bags for you to show you how much space there is in there.
- Now I gonna crawl in the SP2, which is this guy here,
- so this one of the middle of the series.
- Main difference being that with the sizing is that
- I will have a hood, where as the SP0 I wouldn't
- have a hood.
- And the SP3 and the four are gonna offer a little
- bit of extra width than this guys here would.
- So just crawling into this bag here now.
- Get my feet right to the bottom,
- lay down in it.
- Super lightweight I can barely feel it around my body.
- I can access the zip on the side
- Now the anti-snag's still pretty good on this,
- not as good as the ones in the heavy duty summit bags.
- But it still works pretty well.
- Now I'm 185 centimetres, six foot one, which is
- just over the recommended height for this bag here.
- And my feet, my feet have got a bit of space
- at the end, especially with that box foot section.
- I've got wiggle space, it doesn't feel pushed up against
- the hem, a lot of room to move.
- I can fit my arms comfortably on the side of my body,
- so the SP3 and the four are obviously gonna offer
- A little bit of extra room in the bag.
- And this hood fits comfortably over the
- top of my head, there should be a little draw cord
- Here somewhere, here we go, I can tighten that right up,
- around my head.
- When you get that done up it feel a little bit tighter.
- My feet are pushing against the end a little bit,
- so I probably actually want the long bag, I reckon.
- But I'm pretty comfortable, and I'm starting to
- feel pretty warm here already.
- Its pretty much all the features of the Spark bags.
- One last thing I do want to do for you though, is
- pack them up in their bags.
- We're gonna pack all three of these up, because
- the sizes range from really tiny through
- unimaginably bigger so.
- Give me a second, I am gonna stuff them all in a bag,
- Show you what they're all like.
- When you're packing your down bag, especially
- These lightweight spark bags, being lightweight
- Fabrics, you just want to be gentle with them.
- Don't roll them, just stuff them into the bag,
- and gently punch them in starting with the bottom.
- Make sure you squash it down.
- Gently squeezing the air out of the fabric.
- And just working way down slowly until the
- whole thing fits in the bag.
- Well that was relatively easy.
- Probably the hardest bag to pack is actually the
- smallest SP0, this one here, cause you've just
- got your fingers to use.
- And that doesn't come with a compression sac though.
- But these ones here, you can squash them down
- a bit more with a compression sac, say work your way
- around, that's reasonably in there now.
- Then the SP1, it squashes down a little bit more.
- You can probably get a bit more out of those,
- For just as a reference I have a now jean bottle here.
- So this is the SP0, modally smaller than a
- now jean bottle.
- The SP2, mildly larger than a now jean bottle.
- And the SP4, which is the expedition bag, is probably
- two to three times the size of a now jean bottle.
- It goes the Spark sleeping bag is an awesome option
- for any lightweight adventure in just about
- any climate and you can grab them online at
- Snowys.com.au at our lowest prices everyday.
