The Hyperlite Mountain Tools Unbound 40L is an ultralight backpack centered at any person short of to lighten their load on their subsequent in a single day backpacking travel or multi-month thru-hike.

Even if it is named the Unbound 40L, it has a complete of 49-liter capability. With a 40L capability in the principle bag and 9L of garage within the aspect and rear wallet.

This smaller-sized pack is probably not for everybody. However after getting a mild and compact sleep machine, have got rid of all of your unneeded luxurious pieces, and wish to prompt with minimum tension to your frame then that is for you.

With a couple of exterior garage places, it’s best possible for locating a spot in your rainy rain jacket after that brief rain bathe. Talking of rain, relaxation confident that your equipment will keep dry on this water-proof backpack that even has seam sealing to make sure your equipment remains dry.

The aspect wallet are the very best position for sporting a number of liters of water right through that dry wilderness segment of the path. Hyperlite Mountain Tools in reality put some concept and energy into the exterior garage spaces in this pack.

General, that is the very best backpack for thru-hiking or the ones shorter multiday backpacking journeys the place you don’t have an excessive amount of stuff. An actual favourite for minimalists.

Body, Harness, and Hipbelt

The backpack is held in form via a verticle aluminum keep this is surrounded via 1/4 inch foam after which lined with the Dyneema Subject matter. This mix does a just right activity to stay the pack in its unique form.

The Shoulder Harness is relaxed and has the choice of including some extras to assist you to customise your pack harness. Pieces equivalent to a digital camera pod, shoulder strap bag, or a small fanny bag such because the vice versa that may strap around the sternum strap give added equipment sporting flexibility.

It’s refreshing that the hip belt comes with water-proof aspect wallet. I like those. Absolute best for cash, keys, lip balm, sunscreen, snacks, telephones, headphones and so a lot more. It’s even sufficiently big to suit maximum ultracompact Climbing Cameras. They arrive whole with a water-proof zip and are sufficiently big to stay most of the people glad. And if you wish to be ultralight, you’ll take away it, or change it which is a great choice if you happen to achieve or shed weight. Or possibly you need to percentage the pack with a couple of other people.

At 30.1 oz. or 853 grams which puts this backpack on the heavier finish of ultralight backpacks, however neatly throughout the light-weight backpack class. There are lots of different backpacks available on the market which can be lighter however few can be made in addition to this.

Load sporting base weight

Hyperlite Mountain Tools recommends that the Unbound 40L backpack has a load prohibit of round 40 lb / 18 kg. With a light-weight base weight of round 10 lb / 4.5 kg and below this backpack rarely feels adore it is to your again. It’s tremendous relaxed and does a just right activity of distributing many of the load onto the hip belt.

Once I examined the backpack with heavier a lot I discovered it used to be ready to hold the a lot moderately neatly. Like any ultralight backpacks, you will have to watch out when packing. You will have to make sure that there aren’t any sharp items towards your again. Although there’s a padded segment between your equipment and your again, it is just 1/4 of froth, so no longer just right sufficient to prevent an object like your cooking pot from poking into your again. Pack your backpack moderately.

If you’re having a look to shop for a backpack like this, then you have already got light-weight mountain climbing equipment or can be purchasing some quickly. Simply don’t have heavy equipment on this pack, decide to sporting much less and you are going to love the HMG Unbound 40L Backpack.

Subject matter

The HMG Unbound 40L backpack makes use of a few other fabrics, specifically Dyneema Composite Hybrid Subject matter at the major frame of the pack, Dyneema Stretch Mesh at the again and backside wallet, Hardline with Dyneema at the straps, nylon daisy chain webbing and nylon elastic compression straps at the aspect to safe your water bottle, tent poles or trekking poles.

Dyneema Composite Hybrid Subject matter in two other weights, specifically DCH50 and DCH150. The Dyneema Composite Hybrid Subject matter is more potent and extra abrasion resistant than customary Dyneema Composite Fiber.

Standard Dyneema Composite Fiber is 100% water-proof, however the hybrid building of the fabric isn’t 100%. For many functions, it’s so as regards to 100% water-proof that you just must fear an excessive amount of about your equipment in a rain hurricane. Simply don’t use the backpack as a floatation tool on a river. Or use a dry again when canyoning or pack rafting.

Throughout preliminary checking out, there used to be no rain. So I loaded the pack with all my equipment and poured water in all places it. As anticipated the whole thing stayed dry.

The again wallet and backside pocket makes use of a slightly new product known as Dyneema Stretch Mesh. I’m not able to remark at the long-term energy and sturdiness of this product as there don’t seem to be too many backpacks made with this subject material.

Throughout checking out, I attempted to poke a hollow within the subject material with sticks and failed. As I kind up this assessment I made up our minds to check out and poke a hollow in it with a pen. The pen used to be ready to move partway during the subject material and be got rid of with out ripping any of the fabric. So, all seems just right for the long-term energy of the fabric. It’s indisputably higher than what maximum different manufacturers use nowadays. I ponder how lengthy sooner than Dyneema Stretch Mesh is extra broadly followed via different manufacturers.

Dimension and Capability liters

The Hyperlight Mountain Tools Unbound 40L backpack is available in just one dimension, being 49 liters. It has a beneficiant 40 liters of interior garage and 9 liters of exterior garage within the type of rear and aspect wallet.

The design of the pack lets in the principle compartment to extend moderately just a little for the ones instances you will have a large load to hold. Like the primary day leaving the town when thru-hiking. Due to the roll-top design and compression straps the pack can also be closed to a smaller dimension when wanted. I’m a groovy of roll-top closures on backpacks.

The rear wallet have an odd machine of three wallet. There’s one major pocket on the rear, every other situated additional down at the rear, and one beneath.

The principle rear stretch pocket makes use of Dyneema Stretch Mesh subject material. This is a beneficiant dimension, sturdy, and has just right stretch houses. Once I examined this backpack I discovered this pocket to be best possible for storing rain equipment, snacks, sunscreen, trash, and bathroom paper.

Additionally it is attached to a smaller outdoor pocket that can be utilized to get right of entry to pieces on the very backside of the principle pocket. The smaller stretch pocket isn’t very giant however may be used to retailer pieces equivalent to mild snacks, sunscreen, or bathroom paper.

There also are some at hand daisy chain webbing loops at the again that may be used to connect one thing like a mountain climbing allow tag, hand sanitizer, or equivalent. Even if there aren’t any ice awl loops I’m positive it’s essential use the webbing to make one thing paintings. I assume the daisy chains might be used for anything else your creativeness comes to a decision, a small carabiner with a ingesting mug, possibly.

As for the pocket beneath the pack, this can be a stretch pocket that opens from one aspect simplest. I query the sturdiness of this backside pocket, even though it’s made with Dyneema Stretch Mesh.

Throughout the checking out of this product I might throw the pack at the floor totally loaded and take a seat at the floor with the pack nonetheless on my again I had no problems however I’m no longer positive how the pack would take care of a couple of hundred days of me doing this. Having mentioned that, this can be a just right position to retailer one thing like your sound asleep pad.

The HMG Unbound 40L options 2 aspect wallet which can be a beneficiant dimension and sufficiently big for a few water bottles. I used to be ready to suit a 2x 1L bottle in each and every pocket for a complete of four liters of water sporting capability. It might be stretched to hold a bit of greater than that if you happen to use water bladders such because the Platypus vary of bladders.


The pack is made with one of the most most powerful and maximum sturdy variations of the Dyneema Material. As such this pack is tougher than another Dyneema Backpacks available on the market from different producers. This added sturdiness comes on the slight value of weight. This pack is a bit of heavier than equivalent designs from different producers. That’s the trade-off in terms of ultralight backpacking. Sturdiness vs weight.

General, you shouldn’t have any problems with this pack. It is rather sturdy. I simplest query the long-term sturdiness of the Dyneema Stretch Subject matter at the backside aspect of the backpack. Time will inform on that one. Having mentioned that, the Dyneema Stretch subject material is far better than virtually every other mesh subject material that I’ve observed or used.

Water resistance

As discussed within the subject material segment of this assessment, the fabric is water-proof however no longer 100%. I might no longer use this backpack when pack rafting for example. However I’m assured that you’re going to haven’t any problems when the usage of this backpack within the rain.

In fact, anything else at the outdoor of the pack, whether or not within the aspect wallet or rear wallet gets rainy.

Sizes and Have compatibility

The HMG Unbound 40L backpack is available in 4 sizes, specifically Small, Medium, Huge and Tall. I discovered the sizes to be precisely as mentioned however with sufficient wiggle room to assist you to are compatible into a couple of sizes, particularly if you’re in-between sizes.

Wearing Water – wallet or water bladder pocket

The Unbound has higher aspect wallet than their cousins the South West and Windrider. With the bigger aspect wallet comes a greater and extra safe solution to lift water bottles or a water bladder. There is not any skill to connected and use a hydration bladder throughout the backpack.

HMG Unbound 40L vs different backpacks

The HMG Unbound is up towards some stiff festival within the ultralight backpack marketplace. One of the vital stiffest festival comes inside their very own lineup of backpacks, the HMG Southwest, HMG Junction, and HMG Windrider.

It might be mentioned that the Unbound is a lighter and extra elementary model of the Junction with extra exterior garage choices and constructed with light-weight thru-hiking in thoughts. And for that serve as, this backpack excels.


The Hyperlite Mountain Tools Unbound 40L is available in at round $369 on the time of this assessment. That puts it on the upper finish of the fee vary for ultralight backpacks. There are a few ultralight backpacks which can be dearer however personally, the standard of this top-tier backpack makes it value the price.


The brand new Hyperlite Mountain Tools Unbound 40L Ultralight Backpack is likely one of the higher backpacks available on the market in 2023. There’s little or no to fault on this pack and so much to love. As an example, in comparison to different light-weight packs the HMG pack appears to be tougher and must closing just a little longer than another packs. However at 49 liters of general capability, it is rather a lot for the ultralight backpacker who has already dialed of their ultralight backpacking equipment.
