DWR
The DWR coating makes the fabric water repellent, so that water forms droplets on its surface and runs off instead of soaking in. This protects the fabric from getting wet quickly, providing greater comfort in wet conditions, but does not guarantee full water repellency.
Polygiene®
Antimicrobial technology to inhibit fabric odour. The use of silver ions has the effect of inhibiting the growth of bacteria in the fabric fibres. This keeps the garment fresher for longer, even after intense exercise.

    STEP 1: MEASURE THE LENGTH OF YOUR BACK FROM THE SEVENTH KNEE DOWN THE BACK TO THE PLACE WHERE THE LINE CROSSES THE BIOTOMAL RETREAT

    Follow these three simple steps to correctly determine the length of your torso and select the correct size in any Gregory backpack model. Locate the iliac crest - usually the top of the hip bones are located at the level of the navel. Next, locate the seventh vertebra. - This is the largest lump at the base of the neck. With a tape measure vertically the distance between the above-mentioned points - from the seventh vertebra down the spine to the place where the line crossing the iliac crest crosses.

    STEP 2: SELECT A Rucksack MODEL

    Knowing the length of your torso, you can easily check which size of backpack will suit you best in the Gregory model you choose. Keep in mind that all backpacks in the collection are measured equally, regardless of gender, so a size M will correspond to a size M regardless of whether it is a unisex, men's or women's backpack.

    STEP 3: FIT THE BACKPACK

    When choosing the right size backpack, we recommend trying it on with a load. Then make sure that the top edge of the hip belt is about 2.5 cm above the hip crest shelf. The shoulder straps should wrap smoothly around the shoulders and touch the back about 8 cm below the top of the shoulders. If the shoulder straps are below the said 8 cm, try on a larger backpack size.
