 At Ellis Brigham we've been fitting backpacks for more than 80 years. We pride ourselves on our expertise, professionalism and attention to detail. We offer a huge range of the best outdoor backpacks, so wherever your destination, whatever your mountain sport, we're confident that you'll leave with the best item for you. That's our Sure-Fit Guarantee. Sure-Fit is our in-house training programme to ensure that we deliver the right product at the best fit for your outdoor adventures. We always listen carefully to your requirements and love hearing about the adventures you're planning. We'll explain to you how packs are sized and the different back systems available. If required, we'll show you women's specific models. Any information you give us helps us assess which pack is going to work best. We measure your torso length. This is the distance between your C7 vertebrae and iliac crest. This ensures we get the best fitting and most comfortable backpack for you. We use weights to give you an idea of how the bag will feel and show you how to adjust the pack correctly. After this, we'll encourage you to spend some time in the product and explain any features or accessories. We'll also make any final adjustments if needed.
