Hyperlite Mountain Gear Windrider 40L
Meet the Windrider 40L, the ultralight backpack built to handle nearly any adventure. Originally introduced in 2009, this pack has earned its reputation among thru-hikers and backcountry explorers alike for its remarkable combination of simplicity, performance, and durability. Designed for those who move fast and travel light, the Windrider 40L blends the iconic features of Hyperlite Mountain Gear’s original packs with modern upgrades, making it a trusted companion for multi-day treks and alpine missions.
At the heart of the Windrider is the new Dyneema® Woven Composite 3.9 fabric, offering exceptional abrasion resistance while keeping the pack incredibly lightweight and 100% waterproof. This cutting-edge material not only enhances long-term durability but also feels softer and quieter in cold weather—an important touch for comfort and stealth. The pack’s body is complemented by three large external mesh pockets that make organization easy and provide airflow to dry wet gear while you move.
Comfort and fit are equally prioritized in the Windrider 40L. The redesigned shoulder straps and sewn-through back panel follow the natural contours of your body, providing better weight distribution and reducing pressure points during long hauls. An integrated foam back panel and dual-density hip belt with zippered pockets give the support and convenience you need for full-day efforts. Adjustable sternum straps and removable aluminum stays further customize the fit and carry experience.
Functionality is deeply embedded in the Windrider’s design. A roll-top closure with vertical compression straps allows you to easily manage volume and maintain a stable load, while a Y-strap on top secures additional gear. The external daisy chains and removable compression straps give you total flexibility to carry tools like trekking poles or ice axes securely. Hydration is just as seamless, thanks to a simple bladder hang loop and hydroport for quick access on the move.
Whether you’re thru-hiking the Appalachian Trail, navigating alpine ridges, or exploring remote backcountry routes, the Windrider 40L is engineered to go the distance. With its durable materials, thoughtful upgrades, and weatherproof construction, this is a pack that adapts to your ambitions and excels in the world’s harshest environments. It’s not just a backpack — it’s a proven tool built for bold adventures.

Good to have if you've never seen the iTEP exam, but don't rely on it to boost your scores
Format: Paperback
This book is good in that it comes with two practice tests: one in the beginning of the book, one in the end of the book. The grading rubric is helpful too. However, the actual guide part of the book, doesn't help too much with how to improve test scores. What I like least about this guide is that it won't tell you which questions you answered incorrectly on the practice exams. A good test prep guide will tell you what you answered incorrectly, and will tell you what logic to follow to get to the correct answer. In the reading passages, it would be nice to know where I can find evidence to justify the "correct" answer. In the grammar section, it would be nice to know which rule I'm violating. Any test guide should always come with some testing strategies. I.E. If this question is taking up too much time, skip it and go to the next one. This guide lacks simple strategies like that. Simple strategies like that could be useful when incorporated into this guide because there are certain sections on the exam that you can go back to previous questions, but some sections where the "back" button is disabled.
Overall, if you've never seen an iTEP exam before, this book is certainly helpful in that it will give you an idea of what you will be testing for. However, this book alone won't help you achieve a score of 6. The table of contents itself will tell you there are only 86 pages of actual content covering test material. That's not enough to cover how to excel in the exam.
