Finnish-made H-model suspenders with sturdy metal clips and a swift length adjustment. If you're looking for suspenders, buy these. If not, there's probably nothing we can say to convince you.
The H-tab in the back is polymer and adjustable for height. The clips are sturdy and reliable, and nickel-free.
Which back type is superior? Some people claim to have an answer; we think it's a preference thing. Do note some things, though: Y-model suspenders are more straightforward and forgiving. If your pants have a belt loop smack in the center back, you'll have to compromise the perfect suspender clip symmetry. H- and X-model suspenders are attached with four clips so they offer better support overall.
