Review: Tested in a 7 days motorcycle trip to Wales under serious downpours: worked very well - EDIT ------------------------------------------------------- I have had a four days trip to Wales on a Motorcycle and we got caught a few times in very serious downpours, one where I got soaked to the bones but this backpack worked well and nothing got wet inside. Comfort wise, the straps do their job and it was easy to carry on the motorcycle or when walking. The capacity is aready sufficient at the minimum size (straped tight) but I know it can take a lot more. That the last bag I was considering taking for the trip but that was really the perfect one. I'll use it every time I know it'll be wet and muddy. ORIGINAL REVIEW ----------------------------------------- I usually review only things I absolutely like or items I regret having bought. This bag here seems of excellent quality for this kind of price, although I have yet to really test it. The shoulder straps are pretty thin but this should be OK for those using this backpack with jackets. If it's not your case, you can get some cheap shoulder pads to add some comfort (I'll probably do it myself). Two tights pockets inside (zipped and a net), big enough for documents or a phone. The bottom doesn't have any reinforment cover, so the main seams are exposed. It's probably best not to drag it on a rough surface, like a road. But we all know that items of this price range must be handled with a certain care anyway. What actually really impresses me is the phone case. First it was there (some review said they didn't have one). It's made of the same material as the bag with a hard shell at the bottom. The closing mechanism is easy to operate and pinches the case tightly closed. Now, the most impressive part is actually that this case fits my Galaxy Note 20 Ultra with its rugged case on (Spigen Tough Armour). A nearly 7 inch screen phone with a big rubber case. Really astonishing! I thought it would go straight to the bin but this waterproof phone case is actually really useful. I can still operate the screen through the plastic and it'll be good to have when using my phone as satnav on the motorcycle and rainy days. (Apologise for the bad pictures, I couldn't use my phone...)
Review: It's in the bag! - Things I liked about this Earth Pak 35 litre rucksack: Fully water resistant rolltop design, chest and waist straps for stability and comfort when fully loaded, strong loop handle for hand carrying /hanging to store, reflective strip - helpful for walking /cycling in poor visibility, d-rings on both shoulder straps (for external carry; such as sunglasses case, small pouch, headphones case etc...), 35 litre capacity - I fitted sweatshirt. 10 inch tablet (in slip case), 15 inch laptop (in neoprene sleeve), tech pouch (for charging cables, plugs, USB flash drives), GorillaPod SLR mini tripod + smartphone clamp (in neoprene case), 1l water bottle, A5 sized notepad, and had loads of room to spare! 35l size weighs approx. 650g when empty - I weighed it. The bag is very comfortable to wear on long walks - the back panel is well padded. Wide choice of colours - I went for black, for everyday use. As an added bonus Earth Pak supply a water resistant phone pouch which can protect your smartphone at the beach! (My new phone is slightly too big to fit this). The only downsides are those inherent to the rolltop design - no ability to lock the bag, and slow to open and close. No internal organization - small mesh pocket & key clip only. (i use two tech organizer pouches I already own for organization). No external bungee cords - for external carry. There are no external water bottle pockets, so you either have to open the main compartment or externally hang your water bottle (you will have to supply your own carabiner). 100% recommended by me!

## Features

- Waterproof protection: Commercial-grade 500D PVC with thermowelded seams keeps your gear completely dry in this waterproof dry bag, built tough for kayaking, boating and paddleboarding.
- Zipped front pocket: Grab keys, a knife, a lighter or your phone fast from the front pocket of this dry bag without unrolling the main roll-top compartment, ideal for kayak fishing, canoeing and days out on the water.
- Floats on the water: The sealed roll-top design lets this waterproof bag float alongside you through kayaking, paddleboarding, rafting, snorkelling and beach or lake days, so your kit stays afloat if it goes overboard.
- IPX8 waterproof phone case included: Fits smartphones up to 6.5 inches (measured diagonally) and seals with a snap-and-lock closure, keeping your phone, camera or small electronics protected on the boat, kayak or in the surf.
- Sized for every trip: Available from 5L up to 85L, with strap styles that vary by size, from a single adjustable shoulder strap that extends up to 36 inches on the 10L and 20L dry bags to backpack-style straps with a sternum strap for added stability on the 30L and 40L, a great gift for the kayaker, boater or angler.

### ⭐⭐⭐⭐⭐ My go to bag, super strong and waterproof
*by P***L on 27 September 2025*

Ive had this bag a long time now and about to purchase another. If you want a well made, strong and durable wet pak, i can highly recommend this backpack. It has a handy pocket on the front with a very sturdy zip, strong arm straps and is large enough to carry all my gear when backpacking, camping and kayaking. This bag really does stand up to being thrown around and treated ruff but still stays waterproof
