2022 TASK & PURPOSE "BEST OVERALL BACKPACK"
3400 Southwest
$379.00
SKU: 3-10255-1
55L PACK, IDEAL FOR
- 5-7 Days
- Dry, Rocky Environments
- Backpacking & Thru Hiking
On rugged and tight trails, the 3400 Southwest is a flexible performer that can adapt and handle the way gear volumes change for weekend, section, or thru hikes. Ideal when resupply points are less frequent and/or for equipment flexibility is needed. When the extra volume is not in use, the 3400’s top can roll down enough to make the overall size of the pack similar to the 2400, but that additional space can come in pretty handy when you need it.
When the route is thick with vegetation, requires the occasional up and over immovable objects, and calls for “suck in your gut and shimmy through” type moves, the Southwest is the backpack you want up-close and personal. This pack family is made specifically for tough adventures that would rip most other ultralight-style packs to shreds.

Product Reviews and Questions
LOVE IT!
Comfortable, lightweight and durable. Took it out on a 17 mile hike. Hugged my back very nicely without moving too much or rubbing any parts of my body. Easy to get in and out of the main compartment. The water proof design is fantastic for rain / snow. No need for an extra cover.
Waiting impatiently for summer
So far the pack fits and looks great. Waiting for summer to try it out.
Great piece of kit!
Recently received my Hyperlite Mountain Gear Southwest 3400 backpack and am extremely happy with my decision to purchase this piece of gear. The pack is well made and seems quite durable. It is light weight and comfortable with plenty of room to hold all of my backpacking/camping gear. I look forward to getting out on trail this spring to put this pack thru its paces and trust that it will provide satisfaction and reliability for many a mile to come.
3400 Southwest - initial personal review
I've had this pack on my wish list for quite some time. I'm so stoked to finally get my hands on it!
To be honest I'm a little worried about the internal seam tape as there are a number of places where the adhesive has let go and exposed the seam and I'm yet to use the pack. I'm worried that once I begin to roll/ secure the top that this may further cause the seam tape adhesive to fail.
If you have any questions please let me know.
Thanks for your time.
Light & Durable
This is my first UL pack and boy it is way lighter than my Osprey. Love it
