Bonfus Iterus 38L Advanced Lightweight Frameless Backpack for Hiking

The Iterus 38 is a minimalist, practical, and rugged frameless backpack, ideal as a primary pack for advanced lightweight backpacking.

Suitable for multi-day adventurous hikes with a super-light base weight, or traditional weekend trips, it's a dream pack for lightweight backpackers.
The main body of the pack is made from the most advanced Ultra™ X 200: woven from 200D UHMWPE (ultra-high-molecular-weight polyethylene) composite fibers. Compared to equivalent DCH50, it has 3 times the UHMWPE content, while also improving tear strength by 3 times and abrasion resistance by 7 times. Its lining is a 0.75 mil recycled polyester film, also featuring high water resistance.
Ultra™ X 200 incorporates 45° Ultra™ CrossPly strong yarns under the backing film, with its interwoven grid enhancing diagonal tensile strength, preventing delamination, and extending fabric life.
The bottom of the pack uses the more durable Ultra400: woven from 400D UHMWPE composite fibers. Compared to equivalent DCH150, it has 4 times the UHMWPE content, while also improving tear strength by 2 times and abrasion resistance by 15 times, also featuring high water resistance.
Internal seams are treated with UltraTNT™ PSA waterproof tape, which has built-in Ultra™ CrossPly strong yarns to help reinforce diagonal tension and increase the tear resistance of the tape.
The shoulder strap fabric and side pockets are fully upgraded with UltraGrid™ ripstop fabric, which is woven with UHMWPE as a double reinforcement of Double Ultra™ Grid, making it lighter than ordinary ripstop fabric and increasing its tear strength.

．A lashing system for an additional foam back panel can distribute pressure comfortably and enhance comfort.

．Comfortable EVA foam shoulder straps with highly breathable 3D mesh fabric on the inside.

．3D mesh fabric is also used on the inside near the neck to increase breathability and comfort.

．Roll-top opening with a single compression strap, which can also be used to attach extra gear.

．Side pockets feature a double elastic design to securely hold gear, with drainage holes at the bottom.

．Four-point compression cords on both sides are multi-functional, compressing the pack and stabilizing the load, and can also be used to secure gear externally.

．Bottom front features trekking pole/ice axe loops and an elastic loop for upper attachment.

．Large-capacity four-way stretch front mesh pocket, made of durable Nylon/Spandex blend, for quick access to gear.

．Elastic mesh pocket on the left shoulder strap for phone, GPS, snacks, or other small items.

．Webbing loops on the shoulder straps for attaching additional shoulder pouches or other gear.

．Sternum strap with loops can be adjusted up and down in conjunction with the shoulder strap webbing loops, or removed.

．Removable webbing hip belt with two-stage connection loops, adjustable according to individual torso length.

．Quick-access bottom elastic mesh pocket allows retrieval of gear, snacks, etc., without removing the pack.
