Sustainability

·Sea to Summit is recognized for sustainable practices across their product line.

Cost Per Use

·Cordura — Cordura bags and packs routinely last 15-20 years of daily use. The higher initial cost is easily justified.
·Sea to Summit is known for products that hold up over years of use — which typically means a lower cost per use than cheaper alternatives that need replacing.
·Priced around $100 (midpoint of $50–$150 for Bags). At ~15 uses/month, this hits the $1-per-use "worth it" mark in 7 months — and falls to roughly 11¢ per use across a 5-year lifespan.
