Compression straps are for soft items (sleeping bags, clothing)\n- Don't compress rigid items (cameras, electronics)\n- Mixed loads: rigid items in separate bags inside\n\n\u003cstrong\u003eBest compressible items:\u003c\/strong\u003e\n- Sleeping bags (down or synthetic)\n- Puffy jackets \/ insulated clothing\n- Soft camping gear\n- Towels\n\n\u003cstrong\u003eDon't compress:\u003c\/strong\u003e\n- Hard cases (use a different bag)\n- Inflatable items (pad, pillow)\n- Fragile items\n\n\u003cstrong\u003ePer STS FAQ (modular packing):\u003c\/strong\u003e\n- \"First, squeeze the air out, then pack the dry bag into a tight space so it doesn't draw air back in\"\n- Tight packing maintains compression\n- Use multiple bags for

place\n\n\u003cstrong\u003eLong-term storage:\u003c\/strong\u003e\n- Store LOOSE (compressed for months = damaged insulation)\n- Hang from a hook if possible\n- Or store in a bin without

insulation)\n- Drag the bag on rough surfaces (70D is moderate durability)\n- Use harsh chemicals on PU or Hypalon\n- Machine wash or machine dry\n- Store in direct sunlight for weeks\n- Overload beyond the compression straps' capacity\n- Force the buckle (snaps the field-repairable pin)\n\n\u003cstrong\u003eMost common failure points (70D specific):\u003c\/strong\u003e\n- Roll-top closure (forgetting to roll enough)\n- eVac base (puncture from rocks — 70D is more fragile than HD's 500D)\n- Buckle pin (wear over time)\n- Strap webbing (frays at stress points)\n- Field patches fail
