I picked up the Sherpa 100AC Sleeve to keep my power station from getting scratched in my backpack, and it does the job well. The form-fitting design holds the unit snugly, and at only 2 oz it adds basically no weight. Dimensions of 6.25 x 8.5 x .05 in. mean it slips into a bag easily without bulk. It is a simple sleeve, so don't expect padding or extra pockets, but for basic travel protection it works as intended.
