If your bag doesnt meet your expectations, we'll make it right
Incredibly well designed bag! Not only is there a main compartment to store your climbing shoes, but a slot on the inside of the pack I use for my phone and wallet plus two more pouches on the front. Love the colors and materials and stoked every time I get to use it
Well designed boulder bag, with really study materials. i love how it looks too with the vibrant colours. The secret pocket to keep my phone, small wallet, keys at the back is a nice touch. For bouldering, i can pack two pairs of shoes - for me and my partner (EU 46 and EU 36). For sport climbing, i can fit my shoes, harness and belay devices - partner is on his own and also has to pack my chalk bag for me. It can’t fit everything, but actually packs a punch with the sturdy, stretchy material and strong zip. in the last pic i’ve closed the bag over the two pairs of shoes, it closes easily with a bit of extra room for snacks (if you’re good/strong at packing things down). A great bouldering bag, also looks nice as a day bag for a short day out!
My husband and I hate wearing backpacks on multi pitch routes and have been trying to find a solution to minimize what we carry up a wall. This sling bag with the stabilizer strap has solved all of our problems!
It's secure, comfortable, big enough to store necessary items, and doesn't get in the way of our climbing! For reference, we were able to fit 2 jackets, our phones, and snacks in this sling bag during a long multi pitch climb in Squamish!
Highly recommend ditching the backpacks when you can and wearing this sling bag instead!
The Mega beta Climbing Climber Sling Bag has allowed me to put all of my bouldering gear and shoes in one package, neatly packed and ready to go. This conveince cannot be overstated; I was bumbling around with a disorganized setup. Since the Mega beta bag arrived, I have felt a sense of relief that my stuff is ready to go. It also is VERY comfortable to wear and carry. Five star product!
Awesome! Buy one for all of your climbing loved ones. Comfortable, roomy, airy, and high-quality.
