Bought a bunch of different cubes (based off Chase's review) and this was the one I was most stoked for. The square shape and capacity are ideal even for other bags (fits perfectly in my RE Alpha31).
I can get 6 T-shirt's, 1 flannel, 1 sweat, 1 short, 1 Jean, 6 boxer brief, 6 socks, and one light hoodie in this bad boy! Single clothing cube for 1 bag travel unfortunately, putting it into my mission workshop bag was a tight fit. I used the carry handle to pull it out and the handle ripped!
I contacted support and they sent me a new one right away! Amazing support and belief for their products. I'm so happy I purchased this to support a local company with great customer support.
My only hope is next gen one is built like a tank and made for abuse. I want to be able to stuff it to the max and really compress. I won't ding the 5th star because I don't believe it was ever advertised to be bomb proof.
TL;DR - great buy that can fit a lot off stuff, just be mindful to not stuff to the gills and yank the carrying handle.
