43-113 g (1.5-4 oz) per bag — half the weight of HD variants.

Simpler/lighter design — for general dry storage, not compression needs.

Built-in D-ring for securing to boats, bikes, kayaks — single attachment point.

100% recycled nylon — most sustainable body in the Evac line.

Chemical safety verified throughout the supply chain.

Patented 15mm buckle — user-replaceable in the field.

The Evac Lightweight Dry Bag is the simplest version in the Evac line — no compression straps, just a dry bag with the Evac base: What's different from Compression / HD: - No compression straps (saves weight, simpler) - No 4-strap system like the Compression + HD versions - The user compresses by manually squeezing air out (per STS pro-tip: "sitting on a packed Evac Dry Bag is the best way to squeeze the air out") - Then packs the bag into a tight space to maintain compression What's the same: - Same Evac laminate base (air OUT, water IN) - Same Hypalon non-wicking roll-top closure - Same patented Field Repair Buckle 15mm - Same 10,000mm hydrostatic head - Same bluesign approved recycled 70D body Who needs compression straps: - Buyers who want hands-free compression (4 straps) - Bulkier loads (clothing + sleeping bag combos) - Truck-style organization Who doesn't need straps: - Buyers who prefer manual compression - Lighter loads - Save weight (no straps = lighter bag) The trade-off: - Compression bags: heavier (straps add weight) but easier to compress - Lightweight dry bags: lighter but requires manual compression For most use cases, manual compression works fine. The pro-tip is to sit on the bag after rolling the top, then pack tightly.

The Dry Bag has a D-ring attachment point at the buckle — unique to this Evac variant: What's the D-ring for: - Per STS: "D-ring attachment point at buckle for securing to boats, bikes and kayaks" - Single-point attachment (vs the multi-point lash loops on the HD) - Quick clip-in / clip-out Uses: - Kayak: Clip to deck rigging, spray skirt D-rings, or tow line - Bike: Clip to bike cargo cage, handlebar bag, frame loop - Boat: Clip to deck hardware, mooring lines - Backpack: Clip to internal loops in a backpack - Climbing harness: Clip to the gear loop (not for actual climbing load) Why this matters: - One attachment point = simple - Quick deployment - Compatible with standard carabiners - Use with a small biner or strap Practical: - After filling and rolling, clip the D-ring to wherever you're securing - The D-ring is on the buckle end (so the bag hangs from the closure)

Per STS FAQ: "Does the Evac fabric stop air being drawn in after the bag is compressed? No. Air passes easily through the Evac laminate in both directions; it does not work like a 'one-way valve'. See the 'modular packing' FAQ for details on best use." What this means: - Evac laminate is air-permeable both directions - Air goes OUT when you squeeze - Air goes IN if you let the bag "suck" back in - Unlike a one-way valve, there's no "automatic" air retention How to maintain compression: - After squeezing air OUT, pack the bag tightly in a pack/bag - The surrounding gear presses the bag from all sides - Tight packing maintains compression - If the bag has room to expand, air will be drawn back in Implications: - A loose compression bag will re-inflate over time - A tightly-packed compression bag will stay compressed - Not a "vacuum seal" — more like "if there's no room for air, none gets in" Practical: - Modular backpack packing (per FAQ) keeps bags compressed - Loose cargo nets re-inflate (annoying) - Pack gear tightly around the dry bag = sustained compression

Per STS: "Pro-tip: sitting on a packed Evac Dry Bag is the best way to squeeze the air out — then pack the dry bag into a tight space in your bag or pack so it does not draw itself full of air again." The technique: 1. Pack the dry bag with soft items (sleeping bag, clothes) 2. Fold the roll-top 3 times (proper seal) 3. Squeeze the bag with your hands (initial compression) 4. Sit on the bag to compress further (full body weight) 5. Maintain seat position while packing into the main pack 6. Surrounding gear presses the bag = maintains compression Why sit-on-it works: - Body weight = much more pressure than hands - Even compression across the entire surface - Air escapes through the Evac base evenly - No uneven compression = no bulges Common mistakes: - Forgetting to compress (bag is puffy) - Squeezing once and letting it expand back (no good) - Loose packing = bag re-inflates - Rolling the top too few times (leak risk)

The Lightweight Dry Bag shares the sustainability story with the Lightweight Compression version: Sustainable features: - 100% Pre-consumer Recycled Nylon - Bluesign APPROVED - Non-PFAS DWR finish Lightweight advantage: - 43-113 g / 1.5-4 oz (vs HD's 220-370 g) - Half the weight of HD variant - Cheapest in the Evac line ($24.95 entry) What this bag is NOT: - Not as rugged as HD (70D vs 420D) - No compression straps (manual compression) - No multi-point lash loops (just D-ring) Choose Lightweight Dry Bag when: - Weight matters - Manual compression is OK - Single attachment point is sufficient (D-ring) - Sustainability matters (recycled material)
