Women's Harness – Every women's series pack comes equipped with Shimoda's Women's specific Tech Straps and Women's Adjustable Belt. The straps curve away from the chest area while the dual sternum straps eliminate any awkward pressure points. The belt can be adjusted by 2.4 in (6cm) to help women with a smaller waist find a better fit around their hips. Adjustable Torso Height – The X40 has three height options with approximately 7 cm (2.7 in) of vertical adjustment. This means the same backpack can fit short or taller — male or female — torso heights, ensuring a custom fit for everyone. Those with taller or broader torsos can add Shimoda's Booster Kit for greater range in torso fit. Core Unit Modular Camera Insert System – The X40 utilizes Shimoda's Mirrorless Core Unit series. Core Units provide shockproof protection for Mirrorless and DSLR cameras and lenses, and ensure a user never carries more padding and weight than necessary. The X40 v2 Starter Kit comes with a Small Mirrorless Core Unit. Dual Laptop/Tablet Sleeves – Both rear and front panel padded sleeves fit a laptop up to 14 inches in size. Having two sleeves lets you pack both a tablet and laptop while providing options for various packing scenarios. The roll top can expand with a volume range of 7 liters. The top section also has an additional quick-access YKK SplashGuard zipper that makes getting at your gear extremely quick and easy, especially in foul weather.
