I wasn't sure which one to get, the water bottle side pockets made the Festival pack intriguing but I really liked the waterproof material on the Boost II packs, it's a very sleek looking bag in the Mythos black so I went with that. It's also very light weight with easy access to the pockets (it has a fleece lining) and a charging cable to recharge the battery from the wall. The main compartment is spacious and also has a separate lined pocket for laptops. I took it for a spin at the Outside Lands Festival in SF this past weekend and was not disappointed. I wore the bag all day and felt unencumbered. Numerous friends used my bag as a charging station throughout the day, with the battery sustaining its life thanks to the solar panel and the beautiful weather. At first, the price tag scared me off a bit but after using the bag, it's clear you get what you pay for. I can't recommend this bag enough, it's perfect for anyone on the go. If you're looking for a product that is well designed, functional, stylish, and eco-friendly look no further. Hikers/Campers and festival goers take note. ### ⭐⭐⭐⭐ Nice Backpack *by D***E on September 14, 2017* Quality is great and it looks fine, but there are not enough pockets for all of my things. I use the bag for school and it would be nice to have a place to put my writing utensils where they can be accessed easily. I haven't had sufficient time to review the solar panel and battery, but it seems to charge fine while sitting in the sun. ### ⭐⭐⭐⭐ It's a really good solar backpack *by M***A on August 14, 2017* It's a really good solar backpack, charges fast. Only a few things I would work on. There aren't and side pockets for water bottles and it's not that great to take to the beach because all the padding in the back has teeny tiny holes that the sand gets in. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/97104113-birksun-solar-backpack-gunmetal-grey](https://www.desertcart.com.br/products/97104113-birksun-solar-backpack-gunmetal-grey) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-04-24*
