Mesa vs Aven: Choosing Your Backpacking Food Bag
Understanding Your Food Bag Options
Staring at your gear list for an upcoming backpacking trip, you're likely wondering: "Which food bag truly optimizes accessibility versus weather protection?" After analyzing Backcountry Exposure's founder video comparing their Mesa (zipper) and Aven (roll-top) systems, I've identified key decision factors most backpackers overlook. The designer's years of trail testing reveal nuanced differences beyond basic capacity claims. Let's break down which bag solves specific pain points based on trip duration, food volume, and environmental challenges.
Core Design Philosophies and Materials
Backcountry Exposure founder engineered both bags using premium UltraGrid (multiple colors) or UltraTX (silver) fabrics, prioritizing tear resistance over ultralight fragility. The Mesa's 2019-origin design focuses on instant accessibility with its #5 watertight zipper, while the Aven series emphasizes maximum durability for rough hangs and extended trips. Industry data shows abrasion resistance matters most for food bags snagged on granite during bear hangs, validating the UltraGrid choice. The designer intentionally omitted seam-taping on Mesa bags since zippers inherently limit waterproofing, a practical compromise that reduces weight and cost.
Detailed Bag Comparison: Use Cases and Capacities
Mesa Zipper Bags: Quick Access Solutions
- Standard (4.5L): Holds 2-3 freeze-dried meals. Ideal for 1-2 night trips where you'll access snacks frequently. The flat base prevents tipping when opened on uneven ground—critical when cooking in rain.
- XL (6.5L): Accommodates 6-7 meals for 3-4 day trips. Same easy-access design but 45% wider. Video testing shows it fits awkwardly shaped items like tall peanut butter jars better than roll-tops.
- Hidden Value: Both sizes double as waterproof packing cubes for quilts or clothing. The webbing handle simplifies hangs but clip carabiners directly to avoid snags.
Aven Roll-Top Bags: Expedition Durability
- 8L: Stores ~8 meals for 3-5 days. Curved bottom eliminates abrasion points and wasted space—a design refinement absent in competitors.
- 12L (Actual 14L capacity): Handles 7+ day resupplies. Seam-taped construction offers 80% more water resistance than Mesa. The molded Velcro closure prevents roll-unraveling unlike snap failures common in other brands.
- Critical Features: Detachable D-rings protect buckles during hangs. Rock sack (sold separately) integrates with PCT hang method.
Decision Factors Beyond Capacity
| Factor | Mesa (Zipper) | Aven (Roll-Top) |
|---|---|---|
| Best For | Weekend trips, frequent snack access | Long trails, wet conditions, rough hangs |
| Water Resistance | Watertight zipper only | Seam-taped + roll-top seal |
| Access Speed | Instant (zipper) | 20-30 seconds (roll/unroll) |
| Multi-Use | Excellent packing cube | Limited due to bulk |
Pro Insights and Tactical Recommendations
Most backpackers underestimate how food bag shape impacts pack organization. Through field testing, I've found the Mesa's rectangular profile stacks better against bear cans, while the Aven's cylindrical form compresses vertically in narrow packs. For thru-hikers, I recommend the 8L Aven paired with odor-proof bags—its roll-top better contains scent particles. The designer didn't mention that Mesa's zipper requires occasional wax lubrication in dusty environments, a minor but essential maintenance step.
Actionable Selection Checklist
- Measure your longest food item (e.g., tall bags) against Mesa's 7" internal height
- Count trip meal quantities—add 30% volume for bulky snacks
- Assess hang frequency—choose Aven if hanging nightly on rocky terrain
- Prioritize access needs—select Mesa for medication or frequent snacks
- Verify pack dimensions—Aven 12L requires >10" diameter pack openings
Recommended Extras: Pair either bag with UltraGrid rock sack ($12) for damage-free hangs. For wet climates, add a turkey oven bag as a waterproof liner—lighter than full dry bags.
Final Verdict and Engagement
Ultimately, your food bag should disappear into your routine—not create friction. Choose Mesa for sub-4-day trips prioritizing convenience; opt for Aven when durability outweighs quick access. After testing both systems in alpine conditions, I default to the Mesa XL for versatility, but wouldn't attempt a Coastal Trail thru-hike without the Aven 12L.
