For a lightly loaded day pack, determining the exact back length is not absolutely crucial. With trekking or mountaineering backpacks, however, it is essential, as only a perfect fit will efficiently transfer the weight to the hips. With heavy loads or backpacks featuring an internal carrying system, the centre of the hip wings should ideally rest on the iliac crest and the rear pad on the sacrum.
How do you measure back length?
To determine the back length, use a tape measure to measure the distance between the base of the shoulders or the level of the 7th cervical vertebra (which you can feel protruding where the neck meets the spine) and the upper edge of the iliac crest.

When shipping out, the shop found a problem with the item and only sent it out after sorting it out, so that the customer wouldn't have the hassle of dealing with it later. Very good service attitude 👍🏻👍🏻

Very good, I've bought from this shop many times. The quality is good and there are many brands and styles. This time I bought a pair of Normal Tomir 2.0 nn. I chose nn, which means not waterproof, and it's a little lighter than the waterproof version. Personally I feel that non-waterproof is better for Hong Kong weather, as it's more breathable.

非常好，多次在這店購買，品質好，牌子款式多，這次買了對Normal tomir 2.0 nn . 我買nn 意思係不防水，比防水的輕少少，個人感覺香港天氣不防水更好，透氣度高啲
