Learn step-by-step how to adjust your Void Bag for a custom fit, including strap tuning, torso length, and comfort tips for everyday carry.

The Void Bag is a minimalist everyday pack designed to carry your essentials without unnecessary bulk. But even the best-designed pack won't perform at its best unless it's adjusted to your body. A proper fit reduces strain, improves balance, and makes every carry feel effortless. In this guide, we'll walk you through the key adjustments to get your Void Bag dialed in for a custom fit.

Whether you're using it for commuting, travel, or a day hike, taking a few minutes to fine-tune the straps and positioning can make a world of difference. Let's dive into the specifics of void bag adjustment, from shoulder straps to sternum strap and everything in between.

Understanding Your Void Bag's Fit System

Before making any adjustments, it helps to understand the components that affect fit. The Void Bag features a simple yet effective harness system, including contoured shoulder straps, a sternum strap, and adjustable side compression straps. Each plays a role in how the pack sits on your body and how the load is distributed.

The shoulder straps should wrap comfortably over your shoulders without digging in. The sternum strap connects the two shoulder straps across your chest, helping to stabilize the load and prevent the pack from swaying. Side compression straps pull the pack closer to your back, keeping the contents secure and reducing bounce.

For a custom fit, you'll also want to consider the torso length. While the Void Bag is not designed with an adjustable torso like larger packs, understanding where the pack sits on your back is key. The hip belt (if present) or the bottom of the pack should rest at your lower back, not too high or too low.

  • Check that the shoulder straps are evenly positioned on both shoulders.
  • Ensure the sternum strap sits at chest level, not too high or too low.
  • Adjust side compression straps so the pack hugs your back without being overly tight.

Step-by-Step Void Bag Straps Adjustment

Start by loosening all the straps. This gives you a clean slate to work from. Put the pack on with your typical load—whether it's a laptop, books, or daily essentials—so you can feel how the pack behaves when full.

Next, tighten the shoulder straps evenly. You want the pack to feel snug but not restrictive. The straps should follow the natural curve of your shoulders, and the load should feel like it's sitting high on your back, close to your center of gravity. If the pack pulls backward, tighten the load lifter straps (if available) to bring it closer.

Now adjust the sternum strap. Slide it up or down along the webbing until it rests at your chest level, typically just below your collarbone. Clip it and tighten until it feels secure but doesn't restrict breathing. This strap prevents the shoulder straps from sliding outward.

Finally, adjust the side compression straps. These are usually located on the sides of the pack. Tighten them to compress the load and stabilize it. Be careful not to over-tighten, as this can make the pack feel rigid and uncomfortable. The goal is to keep the contents from shifting without creating pressure points.

  • Always adjust with a realistic load to get a true feel.
  • Use the sternum strap as a stabilizer, not a weight-bearing strap.
  • Side compression straps should be snug but not tight enough to deform the pack.

Sizing and Positioning for Different Body Types

The Void Bag's one-size-fits-most design works well for a range of body types, but fine-tuning is essential for maximum comfort. If you have a shorter torso, you may need to tighten the shoulder straps more to keep the pack from sitting too low. Conversely, if you have a longer torso, you might need to loosen them slightly to allow the pack to rest comfortably on your back.

For those with broader shoulders, the sternum strap may need to be adjusted to a higher position to avoid chafing. For narrower shoulders, a lower position might be more comfortable. The key is to experiment with different settings until you find what feels natural.

Remember that the Void Bag is designed for everyday carry, not heavy loads. If you're carrying a lot of weight, consider pairing it with a more robust pack like the Blitz 30 for additional support. But for daily essentials, the Void Bag's minimalist design shines when properly fitted.

Fine-Tuning for Comfort and Stability

Once you've made the basic adjustments, it's time to fine-tune. Walk around with the pack on, bend, and reach to see how it moves. If the pack shifts side to side, tighten the sternum strap. If it bounces up and down, tighten the shoulder straps and side compression straps.

Pay attention to any pressure points. The shoulder straps should be padded and comfortable, but if they're digging in, you may need to adjust the strap angle or loosen them slightly. The back panel should feel breathable and supportive, not overly tight against your spine.

A good test is to wear the pack for 10-15 minutes with your typical load. If you feel any discomfort, make small adjustments. Over time, you'll learn the perfect settings for your body, and void bag adjustment will become second nature.

  • Do a 'bounce test' by jumping lightly to see if the pack stays stable.
  • Adjust one strap at a time to isolate the source of discomfort.
  • Re-check adjustments after a few hours of wear, as straps can loosen.

Getting a custom fit for your Void Bag is all about understanding your body and the pack's adjustment points. With these tips, you'll enjoy a comfortable, stable carry every day. For a pack that offers even more adjustability and capacity, check out the Blitz 30, designed for those who need a bit more room without sacrificing comfort.
