Stretch-Loc TPU Strap 20mm - 4 Pack

The Sea to Summit Stretch-Loc TPU Strap 20mm 4 Pack is a starter kit of four stretch straps in four different lengths: 375, 500, 625 and 750 mm, all 20 mm wide. Every strap pairs stretchy TPU with its own moulded acetal buckle and Keeper Strap, and the whole set comes in yellow, black or Dusk grey.

One of every length

A mixed set is how most people end up using Stretch-Locs, because every job on a bike or pack is a different size. A typical split looks like this:

• 375 mm: a mini pump or a bottle against a frame tube, or a tent pole bag to a fork.
• 500 mm: a rolled jacket under the lid of a pack, or a stuff sack to a rear rack.
• 625 mm: a foam sleeping mat across a handlebar roll, or two paddles held together.
• 750 mm: the long one, at 75 cm, for a bulky dry bag or a bundle of gear on a kayak deck.

We stock the 4 Pack for anyone setting up a bikepacking rig or a gear box for the first time. Once you know which length you reach for most, the matched 2 Packs fill the gaps.

Strap on, pull, done

Loop the strap around the load, push the tail through the buckle and pull. The TPU stretches under tension and grips the surface, so a load does not creep as it settles on rough roads, and the spare tail lies flat instead of flicking about. Each strap has its own Keeper Strap, the small bow-shaped piece that holds the strap on a frame when the load comes off and pads the contact point so paint and fabric do not get scuffed.

Need more reach? Feed one strap's tail through another's buckle and they act as one. With four lengths in the set, you can build almost any combination around an awkward load and split them again at camp.

Built for hard use

Straps this useful get used everywhere, so Sea to Summit covers every Stretch-Loc for two years from purchase against faults in its materials or manufacture. TPU does not take up water, so the straps stay the same on a wet paddle, a dewy morning or a frosty start in the high country.
