It seemed so lightweight, I was worried that it would not be able to handle much. I bought it specifically because of its size (about the size of a lime when packed); we were traveling and I needed something to carry necessities while hiking. Upon using the bag, I found it was able to easily accommodate the weight of my hiking needs (first aid kit, water bottle, camera, wallet, etc) and is made out of material that is tougher than you’d expect at first glance. It may look light duty, but it was exactly what I needed. It is likely not the best choice if this is your only pack, but if you use it to hold only what you need until you return to your campsite/hotel, it’s a great option. I would recommend and would buy again. ### ⭐⭐⭐⭐⭐ Love this very compact backpack! *by J***L on February 1, 2023* Carry this in a pocket of a larger travel backpack. Has come in handy many times. Easily fits in a pocket too. Very strong and lightweight. ### ⭐⭐⭐⭐ Extremly light, shoulder straps can be painful *by J***E on July 30, 2019* This day pack is extremely light! I used this pack on the last 4.5 miles up Mt. Whitney a couple weeks ago. It was just big enough for the minimal gear I took to the top (puffy, wind pants, wind jacket, 700ml water bottle, snacks, at about 3 lbs loaded weight). The only negative is that the shoulder straps have nothing inside to ensure they lay flat against your shoulders. Because of this, the straps scrunch up into a tight "rope" like configuration (especially over the shoulder and in the armpit) which is very uncomfortable after a day hike. This is the only thing keeping this pack from being 5 stars. While it will add some weight, I will be adding a very small section 1/8 close cell foam and silpoly material to the straps to ensure they do not bunch up. It will add less than an ounce to the total weight, but the comfort gained will be well worth it. ## Frequently Bought Together - Sea to Summit Unisex's Backpack, 18 Liter - Nitecore NB10000 GEN 2 Power Bank, Black - Sea to Summit - Airlite Microfibre Towel L - Bath Towel - Ultra Absorbent & Quick Dry - Ultra-Lightweight - Tiny Pack - For Travel & Backpacking - 60 x 120cm - Moonlight Blue - 67g --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/138714399-sea-to-summit-daypack-backpacks-grey](https://www.desertcart.co.th/products/138714399-sea-to-summit-daypack-backpacks-grey) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-05-01*
