What is the Whiteout 30?The Whiteout is one of the toughest yet lightest rucksacks in our range, weighing just 686g and featuring a fabric 30% stronger than traditionally constructed high-end nylon fabrics. It's designed primarily for alpine climbing, mountaineering and expedition use, but also works just as well for those who need to protect their kit from large bodies of water while trekking, canoeing, etc.
What is it made of?Perhaps the most impressive part of this bag is the main fabric. It's made using a Dyneema Composite fabric which is 10% lighter, 30% thinner and yet 30% stronger than high-end nylon fabrics. As if that didn't sound like a good enough CV, it has a TPU film laminated to the inside to provide 100% waterproof protection. If your main criteria in a pack are for it to be weather-resistant, lightweight and simple, the Whiteout should be at the top of your list!
Which backsystem does it use?It's a fairly simple creature, so the backsystem is kept to the absolute minimum. Wide minimalist shoulder straps distribute the load evenly and a removable waist strap keeps the pack still during use. The buckle on the waist strap is crush-resistant, as if the pack wasn't tough enough already! The backpanel itself is lightly cushioned to prevent items inside the pack digging into you during use.
What are its features?The main compartment is slim and tall, placing the centre of gravity closer to your back for superior stability and load control. Entry into the pack is via a fold and roll closure which ensures total waterproofing — simple roll 3 times, snap the buckles shut and you're away. The roll-top design also means the volume of the pack can be adjusted if it's not packed to capacity. If you want to reduce the volume even further, the two included carabiners on the side of the roll-top closure can be clipped to the daisy chain loops down the side of the bag. Clever! Attaching an axe is also a quick and easy process — pop the orange loop on the bottom of the pack through the head of the axe, attach a carabiner to the other side and flip the axe up to attach the shaft to another loop.

Getting the correct fit for your rucksack is as important as getting the fit right for your boots. A badly fitting pack can inflict misery and discomfort and completely ruin your adventure. This guide is designed to help you get the best fit and comfort from your chosen pack so that carrying all your kit becomes a pleasure and not a chore.
ADJUSTING THE BACK LENGTH
If the pack has an adjustable back length, adjust this to your correct level. Your back length is not related to your height but your torso length. Many packs, and specifically the bigger and more technical packs are available in different back lengths or feature adjustable back systems. Contrary to popular belief, your torso length and not your overall height is the key to getting a well fitted pack. Tall people don’t necessarily have long torsos, just as shorter people don’t always have a short torso length.
Your torso length can be found by measuring from your C7 vertebra (the bony protrusion at the back of your neck when looking down) to the height of your iliac crest (top of your hip bones, where you put your hands on your hips). This measurement will give you an idea of which pack back length to choose.
Once you've got the back length sorted, either by selecting the correct size pack or adjusting the back system, you can begin to follow these simple steps to help achieve a comfortable carry.
LOOSEN OFF ALL STRAPS
Before you start fitting the pack, loosen off all the straps as this will make it easier to get the correct tension later.
TIGHTENING THE HIPBELT
Fasten the backpack hipbelt, the general position is the same as where you’d put your ‘hands on hips’ This area is called the pelvic girdle, and what you can feel when you rest your hand on the area is the bony protuberance, the iliac crest. The iliac crest can support the weight from a pack comfortably, and for sustained periods. The padded section of the hipbelt should encompass this and fit securely.
Tighten the straps so the hipbelt feels secure and held firmly around your body. Ensure that the lumbar pad is centered to your lower back to give you maximum support. Remember that your hips carry most of the weight of the pack, so this should be firm but comfortable.
ADJUSTING THE SHOULDER STRAPS
Next, adjust the shoulder straps, pull them until they start to become snug, but ensure that they are not too tight as to lift the pack off your hips. Remember tightening them will stabilise the pack but will increase pressure over the shoulders. If the back length of the pack is correct the shoulder straps will be flush to your shoulders whilst the hipbelt sits in place comfortably. The point where the shoulder straps attach to the main body of the pack should be roughly half way down your shoulder blades; this ensures that the shoulder straps rolls evenly over the top of your shoulders to distribute the weight correctly.
FASTENING THE CHEST STRAP
Fasten the chest strap and pull until taut but not tight, the elastic section should not be extended. This helps keep the shoulder straps from catching in your shoulder joints and keeps the stability of the pack when moving over rough ground.
ADJUSTING THE TOP TENSIONERS
Top tensioner straps link the shoulder straps to the top of the pack. When tightened, their main function is to stabilise the top part of the pack. The optimum angle for these straps in 45º, but they will stabilise the load even when horizontal or at a more obtuse angle. Tighten them until you feel the top part of the pack rest against your pack, over tightening them will create excessive pressure on the front of your shoulders.
ADJUSTING THE SIDE TENSIONERS
Side tension straps are linked to the hipbelt. By tightening these straps you can stabilise the load but reduce the hipbelt flexibility. Where balance is critical tightening them can help you feel more secure. However, if you are striding out over easy terrain it’s better to loosen these straps to allow full hip flexibility.
ADJUSTING THE SIDE COMPRESSION STRAPS
Side compression straps come next, pulling these tight does two things: firstly, it stabilises the load, secondly it can lift the lower part of the pack, repositioning the load closer to your back.
ADJUSTMENTS ON THE GO
Following these steps should give you a comfortable but secure fit on your pack. Sometimes adjustments will need to be made on the go depending on the terrain or the load you are carrying. The perfect fit is very much a personal preference so experiment with different tensions on the pack to find what suits you best.
