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 13.6 oz (385 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.

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.

Comfort

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.

Features:

ALUULA Graflyte™ A composite fabric with 100% UHMWPE fibers for the face fabric and heat welded UHMWPE film that is delamination proof. 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.
Waterproof The Wapta is waterproof for hiking with waterproof ALUULA fabric along with seam taping and heat bonded for the main compartment seams.
Durable Bottom Pocket The Wapta has the first bottom pocket that avoids low durability stretch mesh and instead uses much more durable ALUULA Graflyte™.
Advanced Shaping The shoulder straps use an ergonomic S shape and differential cut, while the hipbelt is comfortably padded and 3D shaped.
Airmesh Ventilation Dual air mesh strips are heat bonded to the backpanel for padding, grip, and ventilation.
Removable Hipbelt The hipbelt is removable to save 115g (4 oz) on fast and light trips.
Advanced Side Compression Laser cut daisy chain system with a versatile dual strap closure is highly customizable to fit anything including ice axes and trekking poles.
Hipbelt Pockets Large dual hipbelt pockets will fit the largest phones and come standard with a refined design that easily operates one handed.
Shoulder Strap Pockets Dual shoulder straps pockets are standard and provide handy storage for phones, bear spray, sunglasses, and small water bottles.
Simple V Top Strap V shaped top strap provides greater security for storing items on top like a tent or sleeping pad, and adjusts more easily than other V top straps with a single motion.
Highest Quality Premium build quality with high end ALUULA fabric, double stitching, heat welding, seam taping, and generous bartacking.
