The Wapta 30 is the premiere frameless backpack for the ultralight hiker. Built with cutting edge ALUULA Graflyte™ material, the Wapta combines innovative features with advanced construction and ergonomic shaping. The result is a pack that weighs as little as 12.8 oz (365 g) while being highly functional, durable, and comfortable. The Wapta 30 is the ideal overnight pack for the ultralight hiker and an excellent day hiking pack for everyone.


With the Wapta 30 we are proud to introduce the first ultralight pack built with ALUULA fabrics. ALUULA has a proprietary process that solves the longstanding problem of how to fuse a durable waterproof film to extremely tough UHMWPE fibers. The result is ALUULA Graflyte™ which is the first composite pack fabric with a 100% UHMWPE woven face to achieve lower weights while retaining excellent durability. The version used here weighs just 98 g/m² (2.9 oz/yd) while offering higher tear strength and abrasion than all comparable fabrics - making an ALUULA pack both lighter and stronger.

ALUULA's Graflyte™ also has many other advantages including more durable long term waterproofness because their proprietary fusion process avoids glue (which adds weight and can fatigue). ALUULA Graflyte™ is also stain proof, UV resistant, fully recyclable, low water absorption, edge stable, and heat bondable.

With the Wapta 30 we are taking advantage of these characteristics to build a lighter, simpler, and more functional pack. For example, we heat weld airmesh strips to the backpanel for ventilation and we take advantage of the edge stable nature of this fabric to laser cut drain holes in the pockets and laser cut tougher ALUULA Durlyte™ into daisy chains that are lighter than traditional webbing.

ALUULA Graflyte Fabric

Graflyte™ V-98 fabric from ALUULA is an advanced pack fabric with a 100% UHMWPE weave face fabric and tough interior film that is molecularly fused on. It has higher tear strength and abrasion resistance than even other UHMWPE based fabrics while being waterproof, recyclable, UV resistant, edge stable, and heat bondable.

Ergonomic Hipbelt

The Wapta's hipbelt uses an advanced design including a differential cut (so the hipbelt naturally wants to curve) and 3D shaping (to cup your hips) which improve comfort. The belt is removable for those who want to go even lighter.

Airmesh Ventilation

Airmesh strips are heat bonded to the backpanel to provide a more comfortable surface and add ventilation without compromising the waterproofness of the pack.

Durable Pockets

The front pocket, side pockets, bottom pockets, and hipbelt pockets are all made from ALUULA Graflyte which is far more durable than typical stretch mesh pockets. We also use "protected elastics" where the elastics are sewn inside the main fabric to guard them from damage.

Laser Cut Details

The "daisy chains" on the sides of the pack and shoulder straps are laser cut from ALUULA Durlyte™ to provide a highly versatile attachment system at a lower weight than webbing. This system accomodates a wide range of compression and attachment needs including ice axe and trekking pole attachment. We also use laser cutting to create simpler and lighter drain holes on the pockets.


The Wapta's feature set is carefully designed to provide excellent on-the-go access to your gear while improving durability, versatility, and simplicity.

Most uniquely, the Wapta has a bottom pocket that provides quick access to larger items like mitts and hats while solving the common problem with previous bottom pockets: the use of low durability stretch mesh in this high wear area on the pack. Instead of stretch mesh, the Wapta uses pleats (folds) to create the first bottom pocket without the vulnerability of stretch mesh. A similar philosophy applies to the front pocket, which is a generous size and also built from ALUULA to be more durable yet lighter.

Even though the Wapta is a superlight pack, it still has important features like hipbelt pockets and side water bottle pockets. The hipbelt pockets are large and designed for easy one handed operation, while the side pockets have adjustable tension and are shaped for easier access. There are also dual shoulder strap pockets that work great for phones, bear spray, and small water bottles.

The side compression and top strap contribute to making this pack simpler, lighter, and more functional. The side compression uses dual straps which open, close, and cinch at a single buckle. The laser cut ALUULA Durlyte™ daisy chains make this area highly customizable to enable a diverse range of storage and compression possibilities including ice axe and trekking pole attachments. The top strap is a V shape that better secures items on top, while using the same dual adjust buckle so it is quicker to use than traditional V top straps.


Despite being a frameless pack aimed at lighter loads, the Wapta places a major emphasis on comfort including our most advanced shaping yet.

That includes shoulder straps with an S-shape similar to our larger Kakwa packs. This shape has been very well received and fits almost everyone better than straighter straps. The shoulder straps also have a differential cut to naturally curve over your shoulders, and feature laser cut daisy chains that provide a wide range of up/down adjustment for the sternum strap.

Most packs in this niche lack a hipbelt or use a minimalist webbing belt, while the Wapta provides a robust padded hipbelt that is three dimensionally shaped to hug your hips and yet is removable for trips when you want to go even lighter.

Most notably, back ventilation is unprecedented in the 1-lbs pack niche and yet the Wapta has dual air mesh strips heat bonded onto the backpanel to provide padding, a nicer feel, and ventilation.

Overall, the Wapta 30 advances what is possible in an ultralight backpack. No other pack near the 1 lbs mark (450g) has this much functionality, durability, ease of use, and comfort. The Wapta is the ideal pack for ultralight adventures from a dayhike up Yosemite's Half Dome, all the way to an FKT of the Colorado Trail or a thruhike of the Continental Divide Trail.

ALUULA Graflyte™

The only composite fabric with 100% UHMWPE fibers (known by the brand name Dyneema®) for the face fabric. This pack fabric gives greater durability for the weight than all others, while also having a tougher interior waterproof film and enabling advanced construction with heat bonding and laser cutting.


The Wapta is fully waterproof including a fabric with a durably waterproof interior film, taped or heat welded seams, and a drybag style roll top.

Durable Bottom Pocket

The Wapta has the first bottom pocket that avoids low durability stretch mesh and instead uses much more durable ALUULA Graflyte™.



The Wapta 30 stands out by offering a fully featured and durable frameless pack for the lowest weight, greatest comfort, and highest build quality.

While you can find lighter packs, any such pack will be lacking worthwhile features (e.g. shoulder strap pockets, hipbelt pockets, padded hipbelt) and using less durable materials. Any pack with a comparable feature set will be heavier, more expensive, and still lacking the high end construction and materials of the Wapta along with comfort features like air mesh on the backpanel.
