Description

Thunderstruck crackles with energy. Electric white lightning bolts tear across a deep black background, creating a bold, high-impact design that's made to stand out whether you're training, teaching or taking centre stage.

Finished with the iconic RockBox skull logo, Thunderstruck brings rock-inspired attitude and serious workout style together in one striking design.

Lightweight yet structured, it’s roomy enough for your daily essentials — from towels and trainers to snacks or a change of clothes. It also fits most laptops, though it’s not padded for full laptop protection. A zipped front pocket keeps the small stuff organised, while a hidden back pocket gives you a safe space for valuables.

With adjustable padded straps for comfort and water-resistant fabric for everyday durability, it’s made for real life — wherever the day takes you.

Pair it with your matching leggings, bra, shorts or headband for the full Wild Legs look.

Spacious Storage: With overall dimensions of 38cm high x 27cm wide x 16cm deep, this bag easily fits your laptop, lunch, change of clothes, and more.

Laptop Compartment: A dedicated internal pouch keeps your tech safe and secure – ideal for work, study, or content creation on the go.
Front Zip Pocket: Measures 23cm x 21cm x 4.5cm – perfect for your phone, keys, or gym pass.
Large Side Pockets: Stash your water bottle, protein shake or umbrella with ease.
Comfort-First Design: With wide, padded, adjustable straps (8.5cm across), this backpack won’t dig in or weigh you down – even when it’s packed to the brim.
Strong & Stylish: Durable zips, reinforced stitching, and a design that gets compliments everywhere you go.
