Small packs are the man-purses of manly men. I say this to justify to the SheFlogger the quiver of them taking up space in the garage majal. After almost a year of abuse we still reach for the Mountain Hardwear Crimper, a hot little number designed for a day at the crag that will be at home wherever you go.
The 900ci capacity Crimper weighs in at just over a pound and a half, putting it squarely in the lighter-than-air class. There are even lighter packs out there, including MH's own Scrambler, but the Crimper is built to take more of the abuse that ape-indexed climbers dish out with 840D HT ballistic nylon construction.
The abundant features are perfectly dialed in for a day climb: the shoulder straps are minimal but not too much so for the max 10-20lb loads you'll carry in this pack, and even include a vertically adjustable sternum strap and high-mounted elastic keeper loops for a hydration tube; there is a minimalist webbing hip belt, and it tucks away into the dual mesh side pockets that are big enough to carry quart bottles; an offset daisy chain allows clipping of miscellany; there are dual ice axe keepers, one an Axe-S toggle (and bottle opener!) and the other a traditional loop, as well as a keeper at the top of the daisy; and a beefy grab handle/haul loop at the top.
Storage is ample with a widely opening main compartment, inside of which is a bladder pocket with keeper clip and a nifty dual pocket mounted on the top third of the outer flap: one zipped with a key clip, and the other a sunglasses pouch with velcro closure. The final pocket is outside, with a vertical zipper running alongside the daisy. It's big enough for a guidebook or other flat items. The Crimper carries great, and sharp stuff inside doesn't gouge your back thanks to the stout HardWave framesheet. The narrow profile is perfect for climbing or ski mountaineering, staying out of the way of swing arms and snarled epithets. Overall the Crimper is a really great example of just-enough engineering from the folks at Mountain Hardwear.
