About this item
- Universal Insert, o-ne Spacer Upgrades Every Backpack You Own: The adjustable straps and lightweight frame fit hiking packs, biking bags, and school backpacks equally well, so you buy o-ne spacer and instantly add ventilated comfort to your entire collection without replacing a single bag or spending on expensive new gear
- Mesh Airflow Channel, the Wind Tunnel That Cools Your Back While You Move: The curved mesh panel creates a dedicated gap between your backpack and your shirt, and as you walk, bike, or hike, the breeze rushes through that channel, evaporating sweat and keeping your back cool and dry even on the most humid summer afternoon
- Sweat Reducing, p-osture Improving, the Upgrade That Makes Every Pack Feel Custom-Fit: The aluminum-reinforced frame redistributes the load more horizontally across your back, pulling your shoulders gently into alignment, reducing the forward slump, and making the pack feel noticeably l-ighter while you stand taller and M-OVE more comfortably
- Lightweight 250g, the Spacer You'll Forget Is There Until You Feel the Difference: Adding almost no weight to your load, the mesh panel and frame weigh less than a half-full water bottle, yet the cooling and support they provide make it feel like you shed pounds from your pack the moment you start walking
- Turn Your Everyday Commute or Weekend t-r-ek into a Cooler, More Comfortable j-ourney: You'll step off the bus without a sweat stain, reach the campsite without an a-ching back, and actually enjoy the walk to school, all because a simple mesh frame transformed the way your backpack carries and the way you feel at the end of every trip

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
