Hyperlite Mountain Gear

Junction Backpack — PCT Edition

Built for Long Water Carries. Proven in the Desert. Trusted on the PCT.

The Hyperlite Mountain Gear Junction is a Pacific Crest Trail–ready ultralight backpack designed to handle extended water carries, high-abrasion environments, and weeks on trail without compromise. From Southern California’s desert heat to exposed ridge walks and unpredictable weather, the Junction delivers dependable performance mile after mile.

Built with fully woven Dyneema® 200-denier fabric, the Junction offers outstanding abrasion resistance against rock, sand, and brush while remaining 100% waterproof—a major advantage during sudden storms or snowmelt crossings. Its streamlined, frameless-inspired design carries heavy water loads comfortably without unnecessary bulk.

Why the Junction Excels on the PCT

  • Desert-Ready Durability
    Dyneema® Woven Composite 3.9 resists abrasion from granite, sand, and repeated pack drops at water sources—outlasting traditional ultralight fabrics.

  • Long Water Carry Comfort
    Redesigned shoulder straps and a sewn-through back panel improve weight distribution when hauling multiple liters through dry sections.

  • Smart Exterior Storage
    Deep side pockets with lower rear access make grabbing water bottles easy on the move, while the center mesh pocket allows wet gear to dry quickly in desert sun.

  • Weatherproof Confidence
    Fully waterproof pack body protects food, insulation, and electronics during storms, snow, or condensation-heavy nights.

  • One Pack, Entire Trail
    Balanced pocket design and adaptable capacity make the Junction suitable from Campo to Canada without needing to switch packs.

Ideal for:
PCT thru-hikers, section hikers, and desert-focused backpackers who want a single ultralight pack capable of handling water-heavy carries without sacrificing comfort or durability.

Available in Julian, CA and at select Pacific Crest Trail mobile gear shop locations.

Key Features

  • Dyneema® Woven Composite 3.9
    Combines ultralight weight with durability and abrasion resistance exceeding heavier Dyneema® fabrics.

  • Waterproof & Trail-Ready
    Fully waterproof pack body designed for demanding, variable conditions.

  • Redesigned Comfort Fit
    Updated shoulder straps and sewn-through back panel improve weight distribution, stability, and long-term comfort.

  • Optimized Exterior Pockets
    Deeper side pockets with lower rear edges for easy water bottle access and secure gear carry; center mesh pocket for drying wet gear.

Additional Features:

Top Closure Roll-top closure system with vertical compression straps allows you to adjust the pack's volume, keeping the load compact, stable and protected from weather.

Compression Top Y-Strap provides compression and top of pack storage for gear.

Back Panel An integrated 1/4” foam back panel pad adds cushioning and support for a more comfortable carry.

Hip Belt Dual density foam hip belt, featuring closed cell foam and spacer mesh, provides comfort and support for long hauls. Hardline with Dyneema® zippered pockets on the hip belt offer easy access to essentials, secured with a reliable #5 YKK zipper.

Stays Two removable, contoured aluminum stays offer support and help distribute the load. Stays can be removed for additional weight savings.

Weather Protection Seam tape on all vertical side seams and behind sewn-on pack features enhances water resistance, keeping your gear dry.

Sternum Straps 3/4" Sternum Strap allows for easy adjustments along shoulder strap daisy chains.

Shoulder Straps Redesigned shoulder straps featuring an adjusted shape for a more natural curve around your neck, providing enhanced comfort. More frequent bartacks provide increased sternum strap adjustment options, allowing for a perfectly customized fit.

Dyneema Fabric Crafted with Hyperlite Mountain Gear's exclusive Dyneema® Woven Composite 3.9 fabric. This fabric offers significantly higher durability at a lighter weight than DCH materials. Its unique fully woven Dyneema face provides exceptional abrasion resistance, feels better to the touch, and reduces crinkling in cold conditions for a superior user experience.

External Carry Customize your carry with removable side compression straps that easily adjust or detach, offering versatile gear attachment options. Opposing buckles allow you to secure items centrally, while daisy chains on the outer pocket accommodate various straps for added external storage flexibility.

Hydration System Stay hydrated on the go with a streamlined hydration system featuring a simple bladder hang loop and a repositioned hydroport.

Ergonomic Fit Sewn-through back panel construction creates a curved shape that locks the interior panel in place providing a more comfortable and durable fit.

DON'T SLEEP ON THESE DIAPERS! (but your baby should)
Size: Size 3 (40 Count)
I was skeptical at first trying out the plush version of this diaper because I thought the mama bear gentle touch was just OK and you can find a better diaper for the same price point. I saw these on prime day for the same price as the gentle touch and said why not. I was very, very impressed. They are soft and flexible with a satin-like exterior; similar to the feel of a hello bello diaper. The plush version definitely feels more quality than the papery gentle touch ones. I first tested the absorbency using 12 oz of water, waited ten minutes and dabbed dabbed dabbed. Seriously NO moisture! In comparison to the gentle touch diaper that had obvious moisture after the same test. I put them to use on my baby, who just for reference is 19lbs, for an overnight and the diaper did not leak and was only damp in the morning, not wet! Amazing. She is a moderate wetter but I still think that performance is great because in comparison to gentle touch, the diaper was wet on the inside after only three hours and I had to consistently use diaper cream so rash wouldn't develop; I would have never used the gentle touch as an overnight diaper. Seriously, for .21 a diaper for size three these diapers are a steal. DONT SLEEP ON THIS DEAL, PICK UP SOME MAMA BEAR PLUSH DIAPERS!

Not the Same 🤍
Size: Size 2 (184 Count)
I loved the Mama Bear size 1 diapers, so I expected the “plush” size 2s to be the same. Unfortunately, they feel completely different. These seem thinner and not quite as absorbent as the size 1 regular pack. The design is also really busy, which makes the wetness indicator harder to see at a quick glance. With babies, that little line matters more than you’d think. I’ll still finish the pack, but I’m not sure I’d repurchase this “plush” version. If you’re choosing between them, I’d recommend sticking with the regular pack instead. In comparison, Huggies still perform better than these for us. 🤍✨ They don’t hold blowouts at all but they do fit well. They’re also not stretchy. I noticed the print on my baby’s legs.

Great cost efficient option
Size: Size 4 (36 Count)
I switched over from Millie Moon and really like these. They’re affordable, don’t have harmful additives, and are soft and gentle on my babies. Holds a significant amount and doesn’t leak even on overnight wears. I like the simple non character design as well.

Every other diaper leaked
Size: Size 7 (92 Count)
I bought these diapers because they were the cheapest available to buy with a gift card my family was given. Normally I use the bulk store brands. The diapers were very hit and miss. It varies from diaper to diaper even in a pack. My son does urinate heavily but even before he would get anywhere near a “full” diaper it would leak! Leading to wet pants and messes. We’ve never had this problem with other diaper brands. Even our cloth diapers hold better than half of these did. For note he falls below the max size for these diapers by at least 5 lbs. I don’t plan on repurchasing these because of the leaking issue. Beyond that they were easy to use like any other diaper, didn’t cause diaper rash, held together, but was subpar in absorption.
