UOG TOP PICK - Gossamer Gear Mariposa 60 Rucksack - We've singled out Gossamer Gear's Mariposa 60 as one of our top recommendations because it is the lightest weight pack with a large 60L capacity. Lots of features show off this pack as being practical rather than minimalist for such a low weight.

Light, tough and plenty of storage options there's a lot to like about the Gossamer Gear's Mariposa 60 Rucksack. Designed for big trips in the hills carrying all you need in comfort.

Gossamer Gear says:

Our bestseller. With a removable internal frame, load lifters, and 7 built-in pockets, this is a gear-hauling workhorse that weighs in at just 2 pounds.

This award-winning pack’s roomy main pocket holds your shelter, clothing, sleeping pad and food. There are seven extra pockets - one mesh for wet stuff, two easy-to-reach for water and high-energy snacks, and the rest for whatever else. Made of custom 100 and 200 denier Robic nylon fabric, this tough, light pack delivers a very comfortable carry even when overloaded with 35 pounds of gear.

Gossamer Gear's 2020 Mariposa 60 Rucksack is still one of our lightest 60 litre rucksacks. This updated version sees a new, pre-attached belt included in the set up along with a change in the padding used in the straps and foam back. The 60 litres is not just the main compartment but also includes the multiple external pockets so that is worth keeping in mind. The pack is still made from surprisingly tough and durable 100-200 denier nylon which is impressive given the super low weight.

The bag gives the appearance of a roll top enclosure but you get a pair of clips to narrow the entrance then the top folds down to be closed with compression straps to keep your pack contents secure. The fold over top has a zipped pocket.  It might be lightweight but the shoulder straps and hipbelt have plenty of comfortable mesh padding. The hipbelt provided with this pack is a medium size so, if you need a small or large size it will need to be bought separately.

Rather than the conventional set up of 2 side stuff pockets, the Mariposa has one massive side pocket which can easily accommodate a light-weight tent. The other side of the pack has 2 smaller pockets useful for stashing items you want accessible on the move. There is a very large mesh pocket idea for carrying wet waterproofs or a tent flysheet. There is a lashing loop which could be used as an ice axe holder but I'm not convinced how effective it would be. To keep weight to a minimum there are no side compression straps on the Mariposa so it will be important to pack it well to keep the load stable.

A superb lightweight pack with no "buts"!

25 years ago I used to backpack with a 70 litre LowePro sack and the lightest kit I could find which still produced an all up carry weight around 13kg. With today’s amazing light weight and low volume kit that weight has come down to about 5kg without the pack. I have tried a few lightweight packs over the years and although they have certainly shaved off the grams, it has always been “… lightweight but …” . That “but” included sore shoulders, chafed waist, sagging or unstable pack position, lack of space, or poor access. The Gossamer Gear Mariposa 60 however is the first lightweight pack I have used where there are just no “buts”. It is quite superb! Mine weighs 985g with the medium belt fitted and that belt puts to shame others I have used on much heavier duty packs. In combination with the internal frame it transfers the weight effectively to the waist and does not slip down as the loading increases. The belt also includes two pouches for quick access to sun screen/midge repellent/ etc… but, unlike many other packs, the pouches are sensible sizes and do not strain the contents when the belt is tightened. The bag internally is just a large sack which has a voluminous top section that can expand to give huge capacity if required, but if not just cinches down over the front of the pack. This top section contains a zippered compartment that is optimum for maps and other flattish items that need quick access. There are four mesh pouches on the outside of the bag. The two smallest pouches will easily hold a 600ml water bottle/midge net/ waterproof jacket etc, while the intermediate pouch is big enough for a lightweight carbon tripod like the Peak Designs CT1. The biggest pouch will handle wet weather gear or expand to allow you to quickly stow a one man tent if you have to break camp in a downpour, or midges, or both. All pouches are fitted with drain holes. The bag has a removable foam panel that is intended to provide cushioning for the back. It is ridged to provide some airflow/reduce sweating. I was a bit dubious initially about how this would all perform, and imagined the rear of the pack turning into a sweaty spongy mess. Fortunately my misgivings were proved completely wrong! The panel ribs are stiff enough to maintain separation but pliable enough vertically to contour to the shape of the back. It looks a bit cheap and tacky but actually performs extremely well. If you have a delicate posterior you can remove this panel to use as a sit mat, but I’ve not yet felt the need. All my camping gear, food, clothes etc for a couple of days or so comes in at exactly 5kg. Add in another 1.5kg for camera gear and 1kg for the bag itself and the all up weight is just 7.5kg. The main part of the bag is barely 65% full with this load so I have huge room for expansion if required. I could of course go down in sack volume but an under filled bag is always more comfortable than an overfilled bag, and the comfort level with a 6kg load in this bag is just superb - I could carry it for days on end without issue. Although I have little need to go any heavier, I have no doubt that the waist belt and inner frame would allow it to easily handle 10kg without sagging. BTW I am 1.75m tall and the medium torso bag fitted with a medium belt fits like a glove. This lightweight pack is certainly expensive but it delivers huge bang for the bucks, with no “buts”!
