How to Choose a Pack Size

Your torso length, not your height, determines your pack size. We recommend the following to determine yours:

  1. Tilt your head slightly forward to locate the bony bump at the base of your neck. (This is your 7th cervical (or C7) vertebra).
  2. Using a flexible tape measure, have someone measure starting at that spot and running down along the curve of your spine.
  3. Place your hands on your hips so you can feel your iliac crest, which serves as the “shelf” of your pelvic girdle. (It’s the first hard thing you feel when you run your fingers down from the sides of your ribcage.) Position your hands so your thumbs are reaching behind you.
  4. Have your friend finish measuring at the point where the tape crosses an imaginary line drawn between your thumbs. This distance is your torso length.
    • Small (15.0” - 17.0” torso)
    • Medium (17.0” - 19.0” torso)
    • Large (19.0” - 21.0” torso)
    • Tall (21.0”+ torso)
  5. If your measurement falls right in between sizes (for example, if you have a 17.0” torso, so you are right on the line between a Small and a Medium), we suggest you choose the larger torso size.

Excellent packs. Shady company.

The products are great - packs & groundcloths. As you can tell from the self glorifying blogs - this company has some problems. They aren't afraid to charge top dollar, but good luck getting your order. I've put in two orders this summer. Neither arrived when it was supposed to and neither order was correct. They don't have a customer service department out of sheer greed. The website is all bells and whistles, until you want your product in under 3 months after ordering or need help. Then it's crickets. I'm still waiting for an order I placed months ago that Hyperlite is telling me already came. It didn't and USPS sent me an email today stating Hyperlite is lying.

It's also interesting to read blogs about how persons hiking the AT felt 'better than the people' in the towns they were passing through because they were dirty (or had a camera). This type of attitude is toxic for the outdoors. Most persons have gratitude and peace in nature - not fluffed up egos rooted in insecurity. Hyperlite, enough trying to be cute. Your business is suffering and your treating customers poorly. 9/14/21

Excellent, Lightweight, Well Designed

This is a tremendously well-designed pack. Wish I had this years ago!!! Thank you so much for making this in the USA!!!

Used on Ap Trail a few times and will use it out west in a few months. Chose this size (4400) for long intervals between resupply and to use in shoulder seasons needing more room. Would be a Number 1 pick for Philmont Boy Scouts for its large volume (when they have to carry lots of extra). Chose Black for durability.

Best things I like: lightweight BUT comfortable; no pack cover required; ability to roll down for smaller size as you "eat off" several days of food; ability to easily fit bear canister in the pack (versus trying to squeeze it in); mesh pockets for keeping things dry and accessible (use the other model if you want to avoid tearing/snagging); Y strap, pseudo load-lifter; pocket for bladder; side pockets that stay relatively dry. What are best accessories: shoulder pockets (outstanding for phone, compass-old school for fog, trees, SPOT, etc.); extra strap kit to keep external items from flopping around; pods to keep things extra dry, organized. What I would like to be modified: an internal small pocket for keys (mentioned in other reviews-could be an accessory); water bottle strap specifically designed for the shoulder strap to carry 1 Liter bottle; HIGHER SIDE POCKET BY ABOUT 1-2 INCHES (to keep bottles from sliding out as you bend over) OR A BUNGIE CORD ON SIDE POCKETS.

Additional Recommendation: You should offer this and other…

Chicago Basin 37.6mi Trip

I recently purchased the 4400 Windrider Pack directly from Hyperlite. I bought this pack to replace my old Kelty pack. I took my first climbing/backpacking trip with 4400 Windrider recently to Chicago Basin, Colorado. Due to COVID-19 the normal train route was closed making a normally 14mi hike into an aprox 37.7mi hike. First my impressions of the pack. The pack is extremely well made with not a hint of shoddy craftmanship. Each seam is well stitched - triple stitched and tape seamed. The Dyneema fabric is just simply bullet proof. The fabric will no doubt hold up to the point of a lifetime worth of a abuse I would say. Dyneema is so indestructible that I believe no amount of rock abrasion and abuse of the pack will put a dent into the Dyneema fabric. Further, I don't even see how Dyneema could be torn or become frayed period - its that tough. Every part of the pack exudes the evidence of real world testing before public release of the product. This is a pack well engineered by real world use, but with careful attention taken to keep the pack as light as possible - maybe too light read below. The quality craftmanship of the pack is evidence of this. One can tell that every detail of the pack is not only well crafted, but well tested. POSTIVES: In addition to the craftmanship of the pack, I found that the lumbar support and hip belt systems were exactly matched to my back's natural contour. The fit of the lumbar and belt system is so well done that I didn't even need to use…

Dix Range - 9/17 to 9/19

I started using an internal frame pack in 2007. I purchased this pack in August 2021 to use for light weight adventuring at Macomb, South Dix, Grace, Hough and Dix. I used it on a couple of training hikes, i.e., I carried my 3L reservoir, some socks, rain gear and lunch to do a 7-mile hike around Hammonasset Lake when it was 100 degrees. Light weight, no problem.

For the Dix Range trip I packed the following: MSR stove, fuel canister, pot, mug, spoon, twig stove, tarp, stakes, sleeping bag, ground tarp, sleeping pad, 12' of 550 cord, Bic, compass, map, first aid kit, solar battery/charger with cords, 3L reservoir, 2-1L canteens, Katadyn water filtration, multi-tool, headlamp, reading glasses (yep, I'm that old), wool beanie, Tilley, 2-trail shirts, 1-pant, 1-short, 3 pairs wool socks, down jacket, gloves, rain gear, sundries, 2-freeze dried meals, trail mix, camera, and hiking poles. I used 1 large pod for wearables and a stuff sack for the rest. The pack had room to spare. Easy adjustments with three cinch straps and extra straps and buckles if I wanted to lash anything to exterior of pack, e.g., snow shoes, poles, etc. The mesh pouches attached to outside of pack are the best feature of this pack.

I parked at Elk Lake. Hiked 2.3 miles with full pack. I experienced a little fatigue in my neck and shoulders, which didn't surprise me due to the fact that this pack does not have an internal or external frame. I recognized this at the outset and carefully packed my…

Took me through the PCT and CDT

I have used this pack for over 5,000 miles. At the end of the CDT, the two stays were poking through, but I’d say that’s a pretty good life on a pack. I used the mesh pocket a lot and never had an issue with it ripping or catching on things (which I had been warned about). I did find the water bottle side pockets stretched out so I had to be careful when bending over because my water bottles would fall out. Also, on the PCT it was my journal - I wrote on it every night with a permanent market at camp. Now I can never get rid of it :). I just ordered the unbound 40 from hyperlite to replace it and I’m excited to try it. I made the switch for the bottom pocket, draw string on the side pockets and back pocket accessibility - aesthetic bonus I’m looking forward to not having my back pocket contents so visible. I did fit the BV500 bear can vertically in the pack and rolled my tent around it like a burrito + stuffed the other stuff around it. My base weight is about 10-12 lbs, and it carried pretty well except the first day out on a long carry, I wouldn’t recommend for heavier loads, you definitely feel the difference. Or if you have a very short torso, I felt like it was borderline too long for me and I’m 5’6.
